Reporting

You should still be able to push it to an xml file as any showed above, have you tried this yet?

Hi,

I have configured a service to check the total diskspace on a linux server using the below command

/usr/local/nagios/libexec/check_nrpe -H 209.207.228.4 -t 60 -c check_disk -a '-w 15% -c 10%

I have actually not used the option -p - path of the drive to be checked (-a '-w 15% -c 10% -p /') - which showed me the info of all the drives mounted on the server. I can view the status of all the drives using this command, however the stats are not getting recorded in the rrd files and graphs show no info. Please suggest if this is the general behaviour or am I doing anything wrong?

When run from the CLI, what is output of the check? Is there performance data included?

[MSPk]

Yes, the performance data of the drive is included/displayed when run from cli...Also, when I click on the performance graph I see different datasources - with drive names - however, there is no data available to plot a graph.

[abrist]

Were drive volumes added or removed to/from this host after the check was created? I ask because rrds (the storage mechanism for perfdata) do not support a dynamic number of data sources, and if the number of data sources change, graphing will cease to function correctly.

[MSPk]

No, there hasn't been any change. We are monitoring close to 50 Linux servers and soem of them show the stats fine, a part of these 50 are showing blank graphs, some of them even say show a message saying no performance graphs available..!!

Hi Team,

This is in continuation to the query posted by MSPk,

Please click on the below link to get more details.

we are monitoring the root disk space for few linux servers and see that perfornamce graphs for some of these server are either blank or not available.

Next step would be to check your perfdata and npcd logs:

Code: Select all

tail -50 /usr/local/nagios/var/perfdata.log
tail -50 /usr/local/nagios/var/npcd.log

here are the logs

It looks like npcd is hitting load and timeout thresholds, lets increase these values. Edit the file:

Code: Select all

/usr/local/nagios/etc/pnp/process_perfdata.cfg

Change:

Code: Select all

TIMEOUT = 5

To:

Code: Select all

TIMEOUT = 20

Also edit this file:

Code: Select all

/usr/local/nagios/etc/pnp/npcd.cfg

Change:

Code: Select all

load_threshold = 10.0

To:

Code: Select all

load_threshold = 30.0

Now restart npcd:

Code: Select all

service npcd stop
killall -9 npcd
service npcd start
