rrd won't graph

[BanditBBS]

Ok, on to an issue with the part of Nagios I understand the least, the graphing!

This is on a 2012r2.9 server FYI.

I have a server where all graphs are populated except for one, the check_disk. Here is the perfdata:

Code: Select all

/=526MB;808;909;0;1011 /dev/shm=0MB;6494;7306;0;8118 /tmp=245MB;1612;1813;0;2015 /usr=12863MB;11809;13285;0;14762 /var=474MB;1612;1813;0;2015 /u01=41550MB;37554;42248;0;46943 /u02=7522MB;60080;67590;0;75101 /u03=101665MB;122684;138020;0;153356

All the charts on performance charts tab or in graph explorer show up empty. I imagine if I deleted the rrd it would probably work again, btu I'd prefer not to lose all the history...any hints on things I could try?

Have you modified the check prior to noticing the issue? Can you show us the service definition? Are you using the "default check_disk" plugin? What is version of the plugin that you are using?

Code: Select all

./check_disk -V

[BanditBBS]

check_disk (nagios-plugins 1.4) 1.56

Its a passive check, so nothing really of importance in the service config, let me know if you still want to see it. The check is run every 5 minutes and sent via nsca.

The check command is:

Code: Select all

check_disk -w 20% -c 10% -e

Did the number of mount point that are being checked change? You may have run into a datasource quantity mismatch. Check the perfdata.log for any errors pertaining to this check.
