Graphs not showing any Data

Kurdt · Post by **Kurdt** » Fri Jul 21, 2006 10:19 am

Hi all

This is my first post, i am currently using cacti Version 0.8.6h on ubuntu 6.06 installed with apt-get, everything works fine, i can log in to cacti admin and view and create graphics, like this one:

As you see, i have no data on the graph and says "nan" in the counter.

I have rrd files generated on /var/lib/cacti/rra, and i have checked paths.

What i am missing? what could be wrong?

Many thanks and sorry if i am missing some information.

Which Graph Template/Host Template do you use? Personally, I'd recommend the "ucd/net" Host Template

First, thanks for your reply, this is what i get with ucd/net graph template :

What do you think?

Thanks in advance

Please click the first wrench and post the whole "rrdtool graph" statement

i now have the very same problem. my data source is net snmp from a FreeBSD box. and i've tried also using debug logging level.

it can retrieve the value, but somehow this is not in the png at last.

i have others graphs, one is netsnmp from the same server (built in ethernet interface) and works fine (at least looks like to it)

i really dont know where to change/edit for resolving this

thanks

matheus

ps: i ask that kurdt excuse me for using the very same space, but as the problem was the same i thought there was no harm ... if there is, please let me know

Please copy the _whole_ statement to the command line, but change

Code: Select all

/usr/bin/rrdtool graph - \
--imgformat=PNG \

to

Code: Select all

/usr/bin/rrdtool graph /tmp/test.png \
--imgformat=PNG \

and run that code. Post any error message.
You may insted goto Graph Management, select your Graph and activate DEBUG mode. This should give you all error messages as well.
Next question: Are you running rrdtool 1.2.x? Please post the output of

Code: Select all

/usr/bin/rrdtool -v

Ok, last instructions were aimed at the "non-displaying graphs". I've just created some small HowTo for debugging NaN's. You may want to consult it at http://forums.cacti.net/viewtopic.php?p=73383#73383

This is what i get from command line and from debug mode:

RRDTool Says:

ERROR: opening '/usr/share/cacti/site/rra/pc009_cpu_system_41.rrd': No such file or directory

Note that this is for the graph "pc009 cpu usage" (the one wich doesn't show a graph at all) not the "nan" ones. With the "nan" ones debug mode i get:

RRDTool Says:

OK

Please distinguish between "Graph Management Debug" (the one you did above) and "Poller Logging Level = DEBUG" which reports to ./log/cacti.log. Switch to the second one (Settings -> Poller Logging Level = DEBUG) and have a look at the file to check even this error. It will happen, e.g. if the specific data source does not give data, fill system full, ...

Reinhard:

I switched to "cactid" poller, and now i have data gathered on my graphs, what do you think was happening here?
I read cacti.log and everything seeems normal (i think). I will continue to use cactid as long as it works...

Well.. it seems that something is not working perfectly as i said: i have this error on cacti.log

07/31/2006 12:29:54 PM - SYSTEM STATS: Time:292.8794 Method:cactid Processes:1 Threads:1 Hosts:3 HostsPerProcess:3 DataSources:12 RRDsProcessed:0
07/31/2006 12:34:55 PM - POLLER: Poller[0] Maximum runtime of 292 seconds exceeded. Exiting.

Something is wrong there, also, if i execute "cactid" i get an mysql error with wrong password, i found a cactid.conf.sample, i edited it to fit my config and change it to cactid.conf, but where should i place this file?

Thanks

This may be caused by a duplicate poller running. Please check all your crontabs, especually /etc/cron.d/cacti

/etc/cactid.conf is good, or the same directory cactid resides in.
