If feasable, dump the database to ascii format and check. The structure of an RRD file is quite simple. It should not be too hard to check this. I've already tried deleting them and they're either getting re-corrupted, or I don't understand what's going on -- Some of the other .rrd's created by the same process are fine, while several (maybe .1%) of them give me this error. The RRD in question has very little data in it, but usually RRDTool just returns a NaN if I ask for something that isn't there, right? This is not correct. If RRDtool gives you NaN values, it is simply returning data that *is* there. The data just is NaN. Of course somebody will correct me if I'm wrong on this. The error is: RRD ERROR: fetching cdp from rra I'm not entirely sure but it seems that you are asking for an entry that is not in any RRA. If you have created the dump, you can easely check this; all available intervals are shown. The @graphOpts variables are: [snip] -s -2000m Is this perhaps a RRD that has no RRA which stores upto 2000 minutes ? Or maybe the 'm' is mistaken to mean months? (just try it by specifying 'min' in stead of 'm').

[rrd-users] Similar function for WithPeak[] in RRDTool
Hi, I was wondering if there's a similar function for MRTG's WithPeak[] function in RRDTool ? Problem: For example 40 % cpu usage on the daily graph gets divided each time it's put into the next graph (weekly, monthly, yearly), and in the end the value gets very little. I dont want RRDTool to average my graphs, how can this be archieved ?

[rrd-users] Re: Similar function for WithPeak[] in RRDTool
Stefan, This can be done by adding RRA's of type MAX to the rrd database. In the graphs you then can point to these 'max' RRA's instead of the 'average' RRA's hth paul *speaking for himself Hi, I was wondering if there's a similar function for MRTG's WithPeak[] function in RRDTool ?

[rrd-users] Re: Help needed on rrdtool create and rrdtool update
Hmm, what I do see is that you have a heartbeat of 3600 secs. Your updates (at least the first two ones, didn't check the other ones) on the other hand are made with a 7200 sec interval. This is well over the heartbeat threshold, so rrdtool will take the value for a NaN.

[rrd-users] Re: Similar function for WithPeak[] in RRDTool
Either by making AVERAGE RRA's that take up many points, so they too average over 5 min's just like the 'daygraph'. Something like: RRA:AVERAGE:0.5:1:288 # takes 288x5min = 24 hr RRA:AVERAGE:0.5:1:2016 # takes 2016x5min = 1 week (haven't tested this though) Another option is to take the max values, assuming your data isn't very peeky.

[rrd-users] Re: Help needed on rrdtool create and rrdtool update
Exactly! The data come in at an unknown timing. That is why I had them updated at random time and different interval. I read about the comparison between heartbeat and step, and didn't seem to find a way around it. In the document written by Don Baarda, it says, .If the interval between samples is longer than heartbeat, the entire interval is considered unknown... Meanwhile, I am not clear about whether this includes the end points of the interval if they are primary data points in an RRD. Serge was right on the data I tried to updated, 7200 is greater than 3600, but I would think RRDTool can be smart enough to determine 99417900 is unknown while 994176000 is 3 and 994183200 is 1, instead of thinking everything in the interval including the end points are unknown. Due to the nature of the data, if RRDTool cannot help, maybe I will need to artificially put a 0 for every missing heartbeat. This isn't hard but is definitely making my job more trivial.

[rrd-users] Re: Help needed on rrdtool create and rrdtool upd ate
Meanwhile, I am not clear about whether this includes the end points of the interval if they are primary data points in an RRD. There are no primary data points in an RRD, only intervals. Well, according to the document of RRD CREATE, there really is something called primary data point as in the paragraph When data is entered into an RRD, it is first fit into time slots of the length defined with the -s option becoming a primary data point. although I still don't understand what it is. :-) The interval labeled as 99417600 (if heartbeat is 3600) is actually the time period from 99417600-99421199. Any data that comes in during that time is considered as representing the time from the last sample to the time of the sample. If there is an interval of heartbeat seconds that does not contain at least two samples, that interval is treated as NaN (unknown). Why should there be two data in an interval? If The samples only present once an hour, there will be only one datum in 3600 seconds. Serge was right on the data I tried to updated, 7200 is greater than 3600, but I would think RRDTool can be smart enough to determine 99417900 is unknown while 994176000 is 3 and 994183200 is 1, instead of thinking everything in the interval including the end points are unknown. Nope. RRDTool is smarter than that, and it thinks that it doesn't have data for an interval if it doesn't have more than one sample in the interval. This is not smart to me. Why can it not just take what it's fed with? Why not use a small step and a large heartbeat? The only thing the heartbeat controls is how much time can elapse between samples without declaring the entire period unknown. Literally, heartbeat should represent your MAXIMUM acceptable time between samples, possibly plus some margin. The thing is, the MAXIMUM is unknown!! Even if I make the heartbeat hugely big, the timestamps that have no data would come up as something inaccurate with the smaller step.
