Fixed In Version: nrpe-2.15-4.1.el6rhs
Doc Type: Bug Fix
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.

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.
