Doc Text:
Previously, due to an issue in the package nrpe, the data got truncated while transferring and there was an invalid data available in the rrd database. This caused failures in pnp4nagios charts display. With this fix, the pnp4nagios charts work properly as the entire data gets transferred from nrpe server.

Description RamaKasturi 2015-06-13 07:04:41 UTC 
Description of problem:
When a physical machine is added to nagios for monitoring pnp4 nagios fails to load the graph

Version-Release number of selected component (if applicable):
gluster-nagios-addons-0.2.2-1.el7rhgs.x86_64

How reproducible:
Alway.

Steps to Reproduce:
1. Add a physical machine to console.
2. Now run configure-gluster-nagios command to monitor the nodes.
3. Click on cpu utilization graph

Actual results:
PNP4 nagios fails to load the graph for physical machine.

Expected results:
PNP4 nagios should not fail to load the graph for physical machine.

Comment 4 Ramesh N 2015-06-13 07:17:02 UTC 
Did u try immediately after running configure-gluster-nagios?. What is the OS version, selinux status, pnp4nagios version?.
Comment 5 RamaKasturi 2015-06-13 07:35:27 UTC 
No,  I am able to see all other graphs and cpu utilization graph for virtual machines works fine. Only for physical machine i have the issue.

selinux status - Enforcing
Os version - RHEL7 and RHEL6.7
pnp4nagios - pnp4nagios-0.6.22-2.1.el6rhs.x86_64
Comment 6 Ramesh N 2015-06-13 08:55:50 UTC 
I got the root cause. This issue is happening because of the NRPE issue reported in bz#1230194. NRPE output is getting truncated after 1023 characters. As a result , CPU utilization details are not returned completely and it corrupts the rrd file. It will be automatically fixed as part of the dependent bug bz#1230194.
Comment 8 Shubhendu Tripathi 2015-06-15 12:55:47 UTC 
Fixed size issue with nrpe and that resolves this issue.
Comment 9 RamaKasturi 2015-06-18 13:24:47 UTC 
Verified and works fine with nrpe-2.15-4.1.el6rhs.x86_64.

CPU Utilization graph loads successfully when physical machine is added to monitor node through nagios.
