Nagiosgraph -- RRD directory is empty
 

Hello

I am having some problems to generate rrd files automatically.
I've installed nagios 3.2.1 together with nagiosgraph 1.4.2. When i try to generate graph from the webinterface, the rrd directory doesn't get populated. However, when i run the perf script 'insert.pl' from the linux console as follows ( perl /usr/local/lib/insert.pl) the rrd directory is populated and i can view the graphs.

Anyone could please help?

Check the permissions on the directory, can the webserver user write to there?

RRD not getting populated
 

I've created the rrd directory as follows
mkdir rrd
chown nagios.nagios rrd
chmod 777 rrd

I've not used Nagiosgraph yet.

However, when using an earlier graphing plugin on an earlier version of Nagios the RRD files had to be manually created with rrdtool before the graphing plugin would start writing Nagios checks into them. I'm wondering if that isn't also the case for Nagiosgraph?

No Idea :(
I've installed nagios and nagiosgraph for the first time and am really stuck..for weeks am struggling..
Any idea how to proceed?

Hi MensaWater.

This is not the case with nagiosgraph. The rrd files are generated when the perl script is run manually for the first time, however they are not updated when subsequent data are generated,

Any clue how to solve this issue?

check nagios config and nagiosgraph log
 

what is in the nagiosgraph log file?

first check the nagios configuration. are you using batch mode or immediate mode to initiate nagiosgraph data processing? ensure that your nagios configuration matches what is described in the 'Configuring Data Processing' section of INSTALL. batch mode is usually the better choice.

then turn up the log level for data processing by setting debug_insert to 5 in nagiosgraph.conf. look at the contents of the nagiosgraph log file to see what is happening. you should see nagiosgraph being invoked periodically to process the nagios perfdata.

then look for a specific service in the log file. ensure that data are being processed properly. the log file should indicate any problems that prevent data processing.

be sure to turn the log level back to 3 or less after you find the problem.

Hi Mathew

please find below the contents of the log file.
I am using batch mode to initiate data processing.

any idea how to debug?

What are your permissions on /var and /var/nagios?

Hi rweaver
 

The permissions for var and var/nagios are

drwxrwxrwx 16 root root 416 Jun 15 14:42 var

drwxr-xr-x 3 root root 104 Jun 15 14:58 nagios

regards

Try chowning -R /var/nagios to nagios:nagios and restart all the daemons related to rrd generation. It's also possible that they're writing their data to different locations and you need to point both to the same location.

Hello
 

Hello ,

I've changed the access rights on var/nagios as follows

drwxr-xr-x 3 nagios nagios 104 Jun 15 14:58 nagios

still not working.

it looks like there is no pattern in the map file that matches your plugin output. /etc/nagiosgraph/map contains patterns that match plugin output/perfdata and associated rules for putting the results into RRD files.

please run one of your plugins directly then post the output. from that we can create a pattern for the output and/or performance data.

Hi all,
Plese could someone help me?
I need to install nagiosgraph, but I cant do this, I am trying this for about 1 month. Actually I am trying to do the libary works, rrdtool.

It is installed when i put on my server: rrdtool -v I can see it.

But I dont know to do it work. Look:

I dont know now what to do. Some idea?
