Doc Text:	Gluster monitoring stops working when the default NRPE config file is overwritten due to use of configuration management tools. With this update, the gluster command definitions are moved to a custom folder. Hence, the Gluster command definitions are retained and they are not affected by multiple tools writing to the default NRPE config file.	Story Points:	---

Description Sahina Bose 2017-05-18 06:35:30 UTC

+++ This bug was initially created as a clone of Bug #1425724 +++

Description of problem:
With the rise of configuration management tools, the default nrpe.conf file often times gets overwritten. A simple solution for this is to move our custom nrpe commands in a special configuration file in /etc/nrpe.d/

Version-Release number of selected component (if applicable):
RHGS 3.1.3 (version independent)
gluster-nagios-addons-0.2.7-1.el7
gluster-nagios-common-0.2.4-1.el7

How reproducible:
always

Steps to Reproduce:
1. Have a configuration management tool that templates the nrpe.conf file
2. See the custom gluster commands disappear

Actual results:
Customer Gluster commands are inaccessible breaking monitoring

Expected results:
Gluster commands are still reachable

Additional info:
Please :)

Patch https://review.gluster.org/#/c/17306 posted to address this. Moved the gluster nrpe commands to /etc/nrpe.d/glusternrpe.cfg

Comment 3 Sweta Anandpara 2017-06-09 10:53:06 UTC

Verified this bz with gluster-nagios-addons-0.2.9-1.el6rhs.x86_64 and glusterfs-3.8.4-26.el6rhs.x86_64.

The section related to gluster in /etc/nagios/nrpe.cfg is moved to /etc/nrpe.d/glusternrpe.cfg. There is no impact on the configured nagios functionality, when tried with fresh install or upgrade. 

Moving the BZ to verified in 3.3. Related logs are pasted below:
