Do you have Nagios XI Enterprise edition or a trial running? You must have either of these for capacity planning to function correctly.

We have nagios xi enterprise edition running on all servers

The graphs/data is not being displayed in capacity planning for slave servers

Can you go to the Advanced tab, and verify that these checks indeed return perfdata? If they do, you should be able to view the graphs just find in the Capacity Planning. One thing to note though, you must have at least one week of data, before you could use the extrapolation options.

We could see results of performance data in advanced tab.but graps are not showing anything.Attached scrrenshhots for reference

[abrist]

Can you post a tail of the following files from the master server? (in code wraps please)

Code: Select all

tail -25 /usr/l,ocal/nagios/var/perfdata.log
tail -25 /usr/l,ocal/nagios/var/npcd.log

[ravish78]

please find attached

[slansing]

A couple things off the bat here, first open the following file for editing:

Code: Select all

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

Then find the line containing:

Code: Select all

load_threshold = 10

Change this threshold to 25 or higher as your system's load is keeping NPCD from processing perf data. This should take care of the problem, now:

Code: Select all

service ncpd restart

Give nagios about 10-15 minutes to process the data and it should start arriving.

Made the suggested changes.Now we are getting below error which checking capacity planning for data from slave servers.

could not open RRD file for reading ,bad filename

[slansing]

Is this being displayed for all of your performance graphs in both Capacity Planning, and Graph Explorer's Scalable Graphs? If so verify that the RRD's actually exist and what their permissions are?:

Code: Select all

/usr/local/nagios/share/perfdata/<Host Name>/*

This was also a bug in 2.2, you may want to try updating to 2012 r2.3.

[ravish78]

hi,
We have upgraded nagios xi to 2012 R2.5 but still we have issues with capacity planning.

I don't see any issues with graph explorer.

I see below kind of entries in /usr/local/nagios/share/perfdata/<Host Name>/*
drwxrwxr-x 2 nagios nagios 4096 Dec 18 14:16 usa7061lx294.epn.uswestgw.xerox.com

Two out of 4 systems are not displaying graphs.Also master server is not showing slave server capacity planning graphs.

Can you let us know how to proceed?
