Most of new SD cards use "wear leveling" that if your system will write to same place on the filesystem that controller in the card wrote data everytime to another place. For bigger lifetime it is a good idea to have Flash not full. Also it is a good idea to use "Industrial grade" SD card which use SLC chips instead MLC or TLC chips at normal flash cards and have much bigger number of writes to cells.

Big problem can be disk performance. You must have enough of RAM for cache. You can enable feature dir_index on ext2/ext3 filesystem. If this is not enough, you can try to setup RAMDISK and work with RRD files in a RAMDISK. For backup you can periodically copy RRD files on a harddisk every few minutes or hours.

I experimentally created colors which looks good for me. They are in contrast
and BW printer friendly. I use brighter values for + and darker for -.
If I need more than 8 colors, I use them again.
There is piece of my perl code with HEX RGB values:
my @colorsin = (
'30FC30',
'3096FC',
'FFC930',
'FF3030',
'30CC30',
'3030CC',
'00',
'CC3030'
);
my @colorsout = (
'00CC00',
'0066CC',
'FF9900',
'CC',
'009900',
'99',
'00',
'99'
);
Best regards,

Hello, >Is there a different way to > get the data from the routers instead of snmp commands (snmpget > snmpwalk) ? Can I get the values from a 64-bit counter ? MRTG doesn't have problem with 64bit counters. You must use right options. For example I create configuration automatically with cfgmaker. I call cfgmaker with this option: "--snmp-options=:::2::2". Options are described here: http://people.ee.ethz.ch/~oetiker/webtools/mrtg/cfgmaker.html When 64 bit counters are not available (for slow interfaces), that cfgmaker reverts to 32bit counters. If you create configuration manually, it will look like this: Target[router.xxx.cz_POS1_0]: \POS1/0:[EMAIL PROTECTED]:::2::2 ... With 2 on the end mrtg will use SNMP version 2 and "ifhcinoctets" on place "ifinoctets".

Is there a recommended method? I have MRTG with RRDTool and about 7000 targets. I have my own indexmaker, which generates HTML pages with targets, one page per device. On html pages I have links to 14all.cgi script which generates pages with 4 graphs for one target. I have simple CGI script which can search "string" in html pages. Generating of graphs is very fast. In past I was problems with speed of generating graphs. There are few critical things: -- It's important to use modPERL in Apache. There are performance problem, when kernel updates rrdfiles from cache to disk. You need enough of RAM for running MRTG and caching of all rrd files. On linux you can look for free ram with "top" command. It's better, when swap is not much used. Newer kernels (2.6) have better memory management. Other thing is speed of harddrive. One 1rpm SCSI Ultra320 harddrive is enough ;-) Processor speed is not critical. 500MHz to 1GHz is enough. With more targets you can tune filesystem.

Detecting of dead host doesn't work on my server.
I made experiment:
Create access-list on switch with 26 targets which denied traffic from MRTG
machine.
MRTG runs for about 10 minutes (normally for about 30 seconds).
Log says this:
-
SNMP Error:
no response received
SNMPv2c_Session (remote host: "router" [192.168.1.34].161)

...repeated for every target...
ERROR: Target[router_fastethernet0_1][_IN_] ' $target->[2644]{$mode} ' did not
eval into defined data
...repeated for every target...
-
Here I have few conclusions:
1. Deadhost doesn't work on my machine.
2. SNMP timeouts doesn't work how expected. 26 targets with 3 tries and 2s
timeouts are 156 seconds from me and not 10 minutes.
I look in to mrtg perl program, search "dead" and found piece with
this message: "Skipping further queries for Host".
But this message is nowhere in my log.
Can somebody help me with this problem?

This bug is in math function and is visible with options --alt-y-mrtg and --alt-y-grid in RRDGRAPH function. Solution is to edit 14all.cgi, find and remove --alt-y-mrtg option from it.

This option only alternatively computes Y axis. This option is relatively new and was not in older RRDTool versions.

[rrd-users] Re: Graph without values......newbie needs help please
Hello,
> # now create the graph
> rrdtool graph ${PIC1} --start ${STARTGRAPH} --end ${NOWTIME}
> --vertical-label "Temperatur [°C]" \ DEF:mytmp=${DBASE}:temp:LAST
> LINE2:mytmp:#FF:Uhrzeit --title "Temperatur USV svr_01" \
you can try to add these options, when you creating graph:
--units-exponent 0
Disable K, M on label...
--lower-limit 0
0 will be always visible in left-down corner.
--alt-autoscale-max
Autoscale Y axis
--alt-y-grid
Alternative grid computing.
You can try --alt-y-mrtg too.
Behavior of some combinations is not correct, but you can find
functional combination for you. For example displaying of Zero
is different with other options. This is maybe changed in last
version, but I don't test it.

I have some problem with 2.10.11. Version 2.10.5 works great.
Probably some PERL incompatibily with your and my version of PERL.

No this is unambiguously bug. Solution is to use older MRTG or maybe upgrade
of your PERL or repair problematic code in mrtg perl program.

I was this problem too. This is bug in --alt-y-mrtg option in RRDTool. This bug is in --alt-y-grid option too, but there are not much visible. This bug is in all versions of rrdtool (tested to 1.0.45) where this command is implemented. With some values is problem visible more, with other values is visible less, but it's still here. Solution of this problem is to edit 14all.cgi script and remove from them "--alt-y-mrtg" option in rrdtool calling. Best solution is to repair computing routines in RRDTool code and sending patch to author, but I'am not programmer :-( I report this before few months, but nobody have time to repair it :-( Pavouk > -Jon Hartman > > MRTG 2.9.17-3 > RRDtool 1.0.45 > 14all.cgi > > I had started using MRTG alone, then converted to rrdtool and 14all.cgi.

[rrd-users] MRTG 2.10.5 to 2.10.11 upgrade problem
Hello,
I was upgraded MRTG 2.10.5 to 2.10.11 and I have problem, that MRTG says on
ALL targets these errors:
--
ERROR: Target[gw3.router.cz_serial4_3_15][_IN_] ' $target->[3738]{$mode} ' did
not eval into defined data
ERROR: Target[gw3.router.cz_serial4_3_15][_OUT_] ' $target->[3738]{$mode} '
did not eval into defined data
--
When I change "mrtg" in bin directory to older version 2.10.5, everything is
OK. Included perl libs I can leave new from 2.10.11.
I have old linux machine with RedHat6.2.
There are PERL 5.005_03.
Maybe there are problem with PERL incompatibility.
Have somebody some ideas?
Thanks, Pavel Ruzicka

[rrd-users] Re: Faster tool to generate graphs using RRD files
Hi, > Now I have aproximately 11000 targets and rrdtool continues being fine to > poll the variables in this targets. But unafortunately another problem > appears: I have about 6500 targets and I found some problematic parts. For faster graphing is needed modperl in Apache. Problem is with writing 6500 files. MRTG gets targets, system (linux) caches data to RAM and after few seconds kernel tries flush buffers on to disk. Now begins hell for interactive applications. System is totally dead for about 1 minute. I have idea, that on this helps more RAM (I have 512MB), faster SCSI disk 15000RPM (I have 7200RPM) and maybe RAID SCSI controller with huge cache. Processor speed is not too important (I have 2x 400MHz). I use 14all.cgi.

However on closer inspection of the created graph, I notice that > the y-scale now has 2 "1.0k" lines. Pretty strange if you ask me. you can use "--units-exponent 0" option, which write "1000" than 1k on the Y axis.

I know, this is possible bug (or feature?) in RRDTool graph function.

[rrd-users] rrdgraph possible bugs
When I use option "--units-exponent 0", then Y axis completely disappear. When I use option "--units-exponent 0" together with "--lower-limit 0", then Y axis disappear, but zero is visible as "-0.0". When I use option "--units-exponent 0" together with "--lower-limit 0" and "--alt-y-grid", then Y axis is displayed correctly and zero is displayed as "0", what is OK. When I use option "--units-exponent 0" together with "--lower-limit 0" and "--alt-y-mrtg", then Y axis is displayed correctly and zero is displayed as "0", what is OK. Can somebody tell me, if I don't understand something, or is this BUG in rrdtool?
