[rrd-users] Re: Median calculations ?
My apologies :) so the 50th percentile would be {2,3,4} here?
(or without the 2...)
No,
I haven't ever used the percentile function of rrdtool, but it should
just return 2.
In your example the 20th percentile is 1, the 40th 2 etc. etc. and the
100th percentile is 50.
The rrdtool documentation says:
This should follow a DEF or CDEF vname. The vname is popped, another
number is popped which is a certain percentage (0..100). The data set
is then sorted and the value returned is chosen such that percentage
percent of the values is lower or equal than the result. Unknown values
are considered lower than any finite number for this purpose so if this
operator returns an unknown you have quite a lot of them in your data.
Infinite numbers are lesser, or more, than the finite numbers and are
always more than the Unknown numbers. (NaN -INF finite values INF)
Example: VDEF:perc95=mydata,95,PERCENT
I don't think it will interpolate if there's an even number of elements
in the array.
Serge.

Does anyone have handy a detailed description of, or the name of the data interpolation algorithm in rrdtool? There are multiple interpolations. If you update more than once in a PDP, the weighted average is taken, iirc. The PDPs are simply averaged into a CDP if the RRA type is AVERAGE.

output: Current Connections 30 map file: /ouput:.*Connections=([\d])/ and push @s, [check_currentconnections [ Connections, GAUGE, $1 ] ]; Assuming this is Perl lingo: First of all your regexp says ouput i.s.o. output. Second of all, I never use square brackets for anonymous arrays. Or are these used as text delimiters? Third, I'm not sure whether and is a logical operator. It might be a bitwise operator. Fourth, your input seems multiline, but you're not using the multiline match statement. This won't work on $_ b.t.w., $_ is (usually) single line. So perhaps it needs to be: $text =~ /output:.*Connections=([\d])/m push @s, qw/check_currentconnections Connections GAUGE $1/; But I might be wrong on 3 out of 4 statements..

my values in my RRD looks correct and drawing the graph seems perfect: 1132578600: 5.5507237333e+03 9.143722e+02 but When I run this same script via cron, (did a test that the path is correct) my values seems to be in bytes when drawing the graph: 1132578000: 6.795650e+02 0.00e+00 Troubles with cron relate to missing paths in 99% of all cases. Be sure to have each file and each binary addressed with a full path name. Both in your script and in your crontab. To debug, you should know what the script outputs when run from cron. To do so, add a: echo $TIMESTAMP:$TRAFFIC /tmp/logfile.txt to your script. Or just echo $TIMESTAMP:$TRAFFIC so it outputs to stdout. In addition add a MAILTO='[EMAIL PROTECTED]' above the updaten.sh line in cron to have the output of your script sent to you.

[rrd-users] Re: How to implement a 'line of best fit' over graphs
Any idea on how would you implement a 'line of best fit' over your graph? Would you just look at an average of all rrd.archives per graph? Then graph that value? A line of best fit is more for finite data sets as in scatter graphs. Rrd archives go on forever, but taking the graphed timespan as a finite dataset could do. Drawing a true sloping line of best fit would take a lot of programming. I wouldn't dare to program the logic in CDEF rpn language. But I'm not a mathematician. Drawing just the average seems a bit crude to me. I'd at least add the standard deviation to it. I have some graphs that do just that, but I store the standard deviation in the rrd database the moment I put the data in the database.

I have been trying to use the --x-grid HOUR:1:DAY:1:DAY:1:84600:%A command to display the day, hoping that this would resolve the problem above.

[rrd-users] Re: rolling average
Is it possible to have a weighted average like eg. 0.5 val[t]+0.3
val[t-1]+0.2 val[t-2] ?
Kind of, I use (val[t-1] - val[t]) * 0.93 + val[t].
I think I stole it from this list once.
By changing the weight factor 0.93, you can change how slow the line
responds.
Together with some catching of exceptions, it becomes something like:
DEF:val=/rrd/bla/..
CDEF:avg=PREV,UN,val,UN,1,val,IF,PREV,IF,val,UN,1,val,IF,-,0.93,*,val,UN
,1,val,IF,+
LINE1:val
LINE1:avg
So PREV has been replaced with:
IF (PREV=UN) {
val
} else {
PREV
}
and val has been replaced with:
IF (val==UN){
1
} else {
val
}

So (to the best of my understanding) it should be COUNTER or DERIVE and as it can overflow (it jumps back to 0 if the monitoring process restarts) i chose COUNTER. Counter protects against counter wraps. Not against randomly resetting counters. Counter is alright, but you need to do something yourself against counter resets yourself. I think your problem is that you expect 4 to come out when you put in a difference of 4. But what comes out is 4/step. You can use a cdef to multiply by the step again before plotting.

I tried this: rrdtool create test.rrd -b now-10d -s 86400 DS:msgs:ABSOLUTE:86400:U:U RRA:AVERAGE:0.5:1:10 and then rrdtool update test.rrd 1128643200:100 which returned ERROR: illegal attempt to update using time 1128643200 when last update time is 1128776944 (minimum one second step) What am I doing wrong? A database that starts 10 days ago and has an RRA with 10 days of samples ends approximately now. You can only add data to the end of the database, rrdtool will shift the values in time. So what you need is a database that ends 10 days ago.

[rrd-users] Re: Entering historical information into RRD
I would like to record the squid access log into a rrd database so that I can know how much traffic was happening at any given time. The problem with this is that the log entries happen *after* the traffic has completed -- ie. the log may indicate that for the last 55 minutes we were doing a long download, comprising 120Mb, which has nothing to do with the last 5 minutes. I would like this to be added to my RRD data, after the fact. hmm, that would mean you can never really trust your rrd graphs. There may always be a download still happening that you are not seeing. But the simple answer is no. Rrdtool does not like old data. You can dump the rrd file to text, add the data in a script and restore the file. You can also keep the data in a (sql) database and generate the rrd database at the moment you need a graph. And there are probably other tricks if you let your imagination get wild. But inputting data and changing it later on with rrdtool update is not possible.

[rrd-users] Re: How get CPU and Memory values
But how can I calculate the processor load with the numbers from /proc/stat ? I didn't understand what they represent... can you help me? do you have an example script or the calcule to do this? The contents of /proc/stat differ among kernel versions and among linux distributions. But there's a man page. `man proc` is what you are looking for. For my old server it says: (the mailinglist program is going to ruin the formatting of this) stat kernel/system statistics cpu 3357 0 4313 1362393 The number of jiffies (1/100ths of a second) that the system spent in user mode, user mode with low priority (nice), system mode, and the idle task, respectively. The last value should be 100 times the second entry in the uptime pseudo-file. Since it is a counter and it is counting 1/100th of a second, you can just take the number, put it in a COUNTER DS in your database and you automatically are storing the cpu usage in percent. `cat /proc/stat` says: [EMAIL PROTECTED] cat /proc/stat cpu 37636778 776 37294156 150024398 cpu0 18825283 409 18999739 74652623 cpu1 18811495 367 18294417 75371775 .

[rrd-users] Re: Big rrd files (too big !)
I need to create reports for tcp_source_ip_addresses, udp_source_ip_addresses, tcp_destination_ports and udp_destination_ports. That's something ntop does quite nicely. Argus is a great tool for capturing traffic and sorting or Summarizing it. For the moment the best way I found is to generated 4 lists (4 top ten). But I want 4hours period reports and 1 daily reports for each list. So I obtain 28 reports that I have to sort to eliminate duplicated values. O.k... For me, I understood that I have to create one rrd file per dest/src port/ip-addr (tcp/udp) I have in my 4 lists. For each rrd files, I create 2 data sources in order to display graphs in bytes or packets, but then I don't know how many RRA I have to create. Just look at how many pixels wide you want to plot your graph. That's about the number of rows your RRA must hold. A bit more Usually is wise. For every view (4 hours, 1 day) recalculate the Number of rows needed and create an RRA that big. I don't know what is the aim to create RRA, for example, for a weekly archive, monthly archive, etc if it's, for example, display graph for one month of captured flows. You can make one big RRA that spans a year in 5 minute samples, But you are not going to use that many samples in your yearly Graph. Therefore it would only eat disk space and processing time. Tailor made RRA's prevent that. One for every view. I think this have a big influence on the size of the rrd files. It sure can. - Op de inhoud van dit e-mailbericht en de daaraan gehechte bijlagen is de inhoud van de volgende disclaimer van toepassing: http://www.zeelandnet.nl/disclaimer.php - For the content of this e-mail message and its attachment(s) the following disclaimer applies: http://www.zeelandnet.nl/disclaimer.php -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdminhttp://lists.ee.ethz.ch/lsg2.cgi

I have a pretty simple rrd files that stores values I collect in a database every 15 minutes. I now want to make it a little like mrtg with a weekly avg, monthly avg and yearlt avg graphs.. Can someone suggest some better rra options here ? my @options = (-b, $START, -s, $STEP, DS:a:GAUGE:1800:U:U, DS:b:GAUGE:1800:U:U, RRA:AVERAGE:0.5:1:999, RRA:MIN:0.5:1:999, RRA:MAX:0.5:1:999); You have a little less than 15000 minutes or 10 days worth of samples here. That'll make a lousy yearly graph. You need enough samples to build a year worth of data. You can go for one RRA that holds more than a year of 15 minute samples or you can make several RRA's with consolidated (averaged) data. The first solution will be quicker to produce, but the last one will be quicker when graphing. I think I would go for: - a little over 2 days worth of 15 minute samples - a little over 2 weeks worth of 2 hour samples - a little over 2 months worth of 8 hour samples - a little over 2 years worth of 24 hour samples So make 4 AVERAGE, MIN and MAX RRAs, each holding the amount of samples mentioned above. the 999 in your example should in the first RRAs be: 2 days+ / 15 minutes = 193. If your graphs are less than 193 samples wide, you can perhaps do with 30 minute samples. Same goes for the other RRAs.

Then you probably will have to use a step size of 1 day. This could be true, but is look very strange and doesn't fit into my idea... When the row size of your highest resolution RRA is 1 week, then your database will contain a value for the end of each week. That value will have an epoch timestamp of N x 604800. With N being an integer. The closest N times 604800 may have been at a wednesday for the start of your graph. You want to have the agility to choose the starting day.

[rrd-users] Re: Adding many data samples at once
foreach (1..5000) {

Push (@DataPoints, ValIn:ValOut:$NewTimeStamp);

shouldn't that be $NewTimeStamp:ValIn:ValOut ?
RRDs::update (test.rrd, @DataPoints);
The problem is that this will produce an error because it
tells me that it
was looking for 2 data points but got 5000 (in this example).
How can I
perform this update in 1 rrd update instead of (much slower)
5000 updates?
Uhm, perhaps this works?

But extracting the data from our archive, we see that averaging is done whenever we set the hearbeat greater than the step. But if we set heartbeat also to 10s, we get Unknown values all the time. Any hints what we could do? update exactly on N x step epoch timestamps. Then rrdtool will not need to interpolate.

[rrd-users] Re: 95th Percentile - Values stored inside RRD file
Thanks Serge, I've changed it to Counter type and I now see that the output of rrdfetch is in transfer rates. O.k.! Basically the router is returning me the amount of bytes that has been transferred for every 300 seconds of SNMP poll. Almost Correct. The counter is continuously increasing with every byte that passes. So the difference betweeen your last poll and the current poll is the amount of bytes that have passed in the nterval. Because this value is cumulative, there will come a time where it's being resetted to 0 due to overflow. I'm curious if rrd is capable of detecting that the value has wrapped around and compute the value correctly. Rrdtool automatically detects and corrects 32 and 64 bits counter overflows. You don't have to specify anything. Just make sure you don't have 2 counter overflows within your polling period. You have that for instance when polling a 32 bits counter every 5 minutes for an interface that transports more than 114 Mps.

[rrd-users] Re: 95th Percentile - Values stored inside RRD file
3) I noticed the raw data inside RRD file contains the cumulative figure (e.g. the octet count is always increasing). Is it possible for me to configure RRD such that it computes the transfer speed and then store them into the file? Instead of dumping the exact figure to the file. I did a rrdfetch and here's a sample of what I got: 047600: 4.1100088879e+08 4.0569527413e+08 047900: 4.1204431180e+08 4.0673533156e+08 048200: 4.1280187560e+08 4.0748254008e+08 my rrd file is created with the option: -s 300, DS:ioct:GAUGE:600:0:U,#input traffic datasource DS:ooct:GAUGE:600:0:U,#output traffic datasource RRA:AVERAGE:0.5:1:28800 because the value (InOctets) is always inreasing, I choose GAUGE thinking that it will help me compute the average and store them in the rrd file. If the input keeps increasing, then is probably is a COUNTER value. As in an snmp byte counter. If you query it every 300 seconds, then you get the amount of bytes that have passed during that 300 seconds. I see no advantage in storing that as a gsuge value in your rrd database. The only interesting value is the amount of bps that have passed and that would be automatically computed is you use a counter ds type. What everage do you want to compute? serge. - Op de inhoud van dit e-mailbericht en de daaraan gehechte bijlagen is de inhoud van de volgende disclaimer van toepassing: http://www.zeelandnet.nl/disclaimer.php -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdminhttp://www.ee.ethz.ch/~slist/lsg2.cgi

[rrd-users] Re: RRDtool and NaN data
I've just today started using RRDtool with Cacti to try and log some traffic data. The RRA files are created with: rrdtool create data.rrd --step 300 DS:ifInOctets:COUNTER:6000:0:4294967296 DS:ifOutOctets:COUNTER:6000:0:4294967296 DS:ifRequests:COUNTER:6000:0:4294967296 2. The heartbeat is significantly larger than the step Perhaps a bit too significant. From the rrdtool create page: A long heartbeat can span multiple ``steps'', which means it is acceptable to have multiple PDPs calculated from a single sample. An extreme example of this might be a ``step'' of 5 minutes and a ``heartbeat'' of one day, in which case a single sample every day will result in all the PDPs for that entire day period being set to the same average rate. So you should probably wait 6000 seconds to see the database getting filled.

I'm struggling a bit with something so simple and stupid, but something that is integral to the whole idea... what colours to use? I have a total of 20 DS's, and sometimes will want all of these to be displayed on a single graph, however, getting the definition between the colours is quite akward, so I'm looking for recommendations of colours to be used that are very different to each other so I can get a 'clear' graph! Good question. I once struggled with this too. The way I solved it was to convert rgb to hsv. That way you get A color wheel. You can then pick colors at even spaced angles From the wheel. For instance if you need 6 colors, take one With h=0, one with h=60, one with h=120 and so on. This will not give you perfect results. You may also want to Change S and V with each color. Let me know if you found a good Algorithm for that :) Here's example code for rgb - hsv and hsv - rgb code conversion. Google will give you lots more. http://www.cs.rit.edu/~ncs/color/t_convert.html To see what the hsv colour wheel looks like, check: http://tinyurl.com/4s8t6 Serge. - Op de inhoud van dit e-mailbericht en de daaraan gehechte bijlagen is de inhoud van de volgende disclaimer van toepassing: http://www.zeelandnet.nl/disclaimer.php -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdminhttp://www.ee.ethz.ch/~slist/lsg2.cgi

Therefore, is there a way of saying: if date before d0, then clamp to lim1 else clamp to lim2 The CDEF language has an LTIME operator that can do that. Don't ask me for details, haven't ever used it. The second approach I considered would be to go into the rrd file and iterate over the values, looking for peaks greater than 2Mb, and replacing them by a linear interpolation between to the two points either side of the peak? The maths doesn't pose much of a problem, I'm wondering about the mechanics of going through the datapoints in the rrd file. That would be a clean solution.

I have an RRD that contains several metrics. The value of the metrics is very different in the range, i.e., one range is between 1 and 200, and another is between 5000 to 2. When I plot these 2 metrics on the same graph, only one line is readable. How can I plot it so that I can see both values, they do not need to be on the same scales. Once way I was thinking of doing is to scale them to below 10, but I need to get the MAX, which I do not know how to get... Can anyone suggest better methods? Not really, you can divide the biggest one by ten and add a comment to the legend saying you did so. GPRINT the MAX value of the original value to the legend and use the scaled version for your LINE. Something like: DEF:small=/var/ DEF:big=/var/ CDEF:scaled=big,10,/ LINE1:scaled LINE1:small GPRINT:big You can also use a logarithmic y-axis.

[rrd-users] Re: problem with displaying metrics of different ranges
For example, I can do this: CDEF:aline4=line4,10,/ But, instead of a static value of 10, I need a dynamic value that depends on the MAX value of the metric. I was hoping to get that information from the info, but all I got for the .max was a NaN: rra[0].cf = MAX rra[0].cdp_prep[0].value = NaN This not the maximum value in te database. You want to know the max value of the average RRA within the Time span you are going to graph. That will define your scaling Factor. If you don't understand that, I urge you to read the tutorial at the rrdtool site. You can get that average in two ways: 1. do an rrdtool fetch with the same time span you use for your graph statement. Sort the values by size with awk/perl whatever and grab the highest (last) value. 2. copy your rrdtool graph statement, remove the lines, area's and stacks and PRINT the max value. Grab that and reuse it in your graph statement to scale your line height. So you'll need to do some scripting.

You can now: - call the cgi in a crontab to generate your graphs and use the mrtg html indexes you already have - Alter the html index files so they do not point at a static image, but point at the cgi instead. The cgi can output a image to the standard output. - Use the cgi to generate your indexfiles dynamically Download one of the two, read the docs and try what you like best. If you view the graphs a lot, then option 1 may be good for you, since the cpu load due to image generation will be lower.

[rrd-users] Re: 95th Percentile - Values stored inside RRD file
I got some questions on 95th percentile and RRD which I hope someone can enlighten. I don't see a connection between your questions and the 95th Percentile value, but o.k... 1) Is .1.3.6.1.2.1.31.1.1.1.6.XXX (e.g. ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifHCInOctets.XXX = Counter64) where XXX refers to a particular interface/sub interface the correct OIDs to use? It is if you need 64 bps counters. You will need them when for Instance you poll every 5 minutes and your interface has a load Of more than 114 Mbps. The device you are polling must support 64 bit counters, though. 2) Since 95th percentile is measuring the rate of transfer, that means I will need to add .1.3.6.1.2.1.31.1.1.1.10.XXX (ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifHCOutOctets.XXX) to InOctets to obtain the exact rate of transfer over the interface? Am I correct? Only on half duplex lines. Full duplex connections have different wires for each direction. There's no logic in adding the traffic Loads of those two. 3) I noticed the raw data inside RRD file contains the cumulative figure (e.g. the octet count is always increasing). Is it possible for me to configure RRD such that it computes the transfer speed and then store them into the file? Instead of dumping the exact figure to the file. Uhm, With my files they don't. The rates are stored, not the Raw counters. Perhaps you are looking for the GAUGE type? The difference is explained in the tutorial on the rrdtool Website.

Oh 1 more question, by using RRA:AVERAGE:0.5:1:1 with a step = 1, this is as good as storing raw data. So why would anyone want to specify another RRA like RRA:AVERAGE:0.5:288:797 or RRA:MAX:0.5:288:797? To save diskspace and processing overhead. You might as well use mysql if you want to save raw values. Rrdtool stores rates and rates are always over a timespan.

[rrd-users] Re: Question on RRA and number of rows
will there be any performance impact if the number of specified rows is set very high? Yes. The file will be bigger. It has to be opened, all the rows will have to be shifted (o.k., that's not too hard) en the file will have to be rewritten Each time you update. And with every rrdtool graph a lot of rows will have to be averaged. Whether it's a piece of cake for your hardware or not: I don't know. A matter of 'trying is knowing', I think.

[rrd-users] Re: A doubt on RRD database
I'm interested in installing RRDTool on my FreeBSD box. I searched the web and found a nice tutorial: What type of database does RRD create? If the database is filled with new data and the oldest is overwritten then how can RRD generate a timeline graph? What's this loop thing? An RRD database is a FIFO. You create multiple RRAs in your RRD database, they will hold your historical data. Every RRA has a type (MAX, AVERAGE, ..), a size and a granularity. For instance - RRA 1: one sample per 5 minutes for 24 hours - RRA 2: one sample per hour for 1 week Say you configured the above and you update your database every 5 minutes. Then after the 12th update, one hour will have passed and 12 values of the First RRA will be consolidated into the second. If the type of your RRAs is AVERAGE, the average of the 12 samples will be added to RRA 2. The oldest 5 minutes sample will be shifted out of the first RRA and the oldest hourly sample will be shifted out of the second RRA.

[rrd-users] Re: A doubt on RRD database
I get the picture. :-) If I would define a time period of 5 months, after the 5th month, time would be continuously shifted after each data collected value, overwritting old data from the begining, never increasing past the defined size for the 5 month data, correct? Totally correct. BTW, thanks Serge for the explanation. You're welcome..

[rrd-users] Re: Data granularity
I have a monitor scripts that gets invoked every time a user interacts with a Web service. There are several Web services that we are collecting data from. Each one goes to a different RRD. Some services are very busy (several hits per second) and some are not (a few hits per week). There is no way for me to identify which is which... I cannot see how this works. Rrdtool collects rates, while you use It as a counting mechanism. But as long as it works for you.. I would like to use 5sec STEP so that there is enough detail for busy services. A few questions to RRD gurus: (1) What is best value for HEARTBEAT? Is 10 seconds too low? That depends on what you want to see in your database. If you set it to 10: - updates that are longer apart than 10 seconds, will cause NaNs to appear in your database - updates that are between 5 and 10 seconds apart, will cause 2 consecutive rows to be influenced, it will be averaged out. If you set heartnbeat to N x step, N rows will be affected by An update, provided your high res RRA has a row time that is equal To the step size. (2) What is the best value for XFF? That also totally depends. Say you have these RRA's: RRA:AVERAGE:0.5:1:1000 RRA:AVERAGE:0.5:10:300 Every step tim, one value will be put in the first RRA. Every 10 step times, 10 values from the first RRA will be averaged And the result will be put in the second RRA. Unless more than 50% Of the 10 values are NaNs. If that is the case NaN will be put in the Second RRA. If the second RRA would read: RRA:AVERAGE:0.9:10:300 Then the average of the 10 values would still be put in the second RRA if 9 out of 10 values would be NaN. So it all depends on what you want to see. In your case I'd probably just dump the hits with a timestamp in a log file and setup a cron job that would do every 5 minutes: - read back all lines and count the hits that were within the last 5 minutes - update the RRD database with the sum of the counted hits as a gauge value.

[rrd-users] Re: Data granularity
rrdtool create resp.rrd --step 5 \ DS:resp:GAUGE:10:0:U \ RRA:AVERAGE:0.999:1:1000 If I do single data point update using: rrdtool update resp.rrd 1106249083:45 and *not* post any update for a while ( 10 seconds ), the RRD fetch command shows that the AVERAGE CF has the following value: 1106249083: nan Why do I have a NaN? Shouldn't I have 4.50e+01 instead? No, rrdtool normalizes your input. Therefore it really only is useful if you enter data in a regular interval. Say you updated like this: rrdtool update resp.rrd 1106249073:15 rrdtool update resp.rrd 1106249083:45 Then after the second update, rrdtool is able to determine the value At timestamp 1106249080. It would be: (45-15) * (1106249080-1106249073)/(1106249083-1106249073) = 30 * 7/10 = 21 It is interpolated because you did not update on a N x 10 seconds timestamp In your case the value is unknown, because you have no previous value to use for interpolation. You need multiple consecutive values for that. Is there a way to retain the value entered for that step? One solution is to set the heartbeat very high, so multiple rows will be filled by a single update, but that is not what you want. What you could try is: - update only on N x 10 timestamps. So 1106249083 would become: 10 x int(1106249083/10) = 1106249080 or - before updating, do a rrdtool last to get the last time the database was updated. Then for ech step size between now and that last update time, update the database with 0. I still would use the log file solution. It's way cleaner.

[rrd-users] Re: MAX-value differs for week/month
Then in rrdgraph I use the MAX-CF to GPRINT the maximum value over the viewed time. For my DEF-statement I also use the AVERAGE. DEF:s1=myfile.rrd:sensor1:AVERAGE GPRINT:total0:MAX: maximum %2.1lf Uhmm.. Where did that total0 come from? I don't see a DEF. From my point of view the MAX GPRINTed in the day-view (-s -1day) should not be higher than the MAX printed in the week-view (-s -1week) or the month-view (-s -1month), cause I store the max-values in my RRD. Correct, but only if you print MAX(MAX), not if you print MAX(AVERAGE). You store the MAX values in your MAX RRA to be more specific. is lower and so on. It seems that the MAX in GPRINT only takes the maximum of the actually drawn values and not the MAX of the RRD, cause the problem does not occure if I use MAX as CF for DEF, which is not what I want. Ah, you see: it prints just what you defined: MAX(AVERAGE) Is this a bug or a feature and is there any way round? It's a feature. It just prints what you ask. The way to print MAX(MAX) is to DEF it and GPRINT it of course..

[rrd-users] Re: Strange rrdtool behaviour (IMHO)
both cases only a fraction more than half the actual loss. If this is indeed the case it should be mostly remedied by making the script run a minute later, or is there a better way to accomplish this? In perl I'd do something like: $timestamp = $step * int($timestamp/$size) You are using a shell script, so you'll have to call some external program like bc, dc or awk. Hmmm, This is logical for the graph itsself, but IMHO shouldn't be for raw MAX and MIN calculations as in GPRINT's. A Maximum is a maximum and by definition shouldn't be averaged if it doesn't have to be for viewing purposes. But a GPRINT is for viewing purposes. Afaik, a GPRINT is not raw, but just as averaged as your graph is. BTW, am I correct in assuming that the only reason to add more RRA's with a bigger step are to minimise CPU-time at graph generation time, or am I missing something obvious here?

The output looks like: /usr/local/bin/rrdtool update /var/rrd/pingstats.rrd N:9.835:10.830:11.584:0 The RRD definatly gets an integer as the fourth argument, as can be seen by the output from the script (which I started saving for debugging purposes), but how is it then possible that I get floats in the last GPRINTs? That's a question that should be added to the top of the rrdtool FAQ. Rrdtool normalizes all input. You are updating using N: and that is probably not on a ( N times step seconds since 01-01 1970 00:00:00) boundary. Secondly, unless the width of your graph is exactly the same as the amount of RRA rows you are printing, rrdtool will average One or some rows over two adjacent pixels. This also averages your Values and that also affects your GPRINTs.
