[Gluster-users] nagios-gluster plugin

[Amudhan P]

Hi,

I am trying to use nagios-gluster plugin to monitor my gluster test setup
in Ubuntu 14.04 server.

OS : Ubuntu 14.04
Gluster version : 3.7.6
Nagios version : core 3.5.1

My current setup.

node 1 = nagios monitor server
node 2 = gluster data node with 10 brick (172.16.5.66)
node 3 = gluster data node with 10 brick


normal nagios nrpe command works fine

root at node1:~$ /usr/lib/nagios/plugins/check_nrpe -H 172.16.5.66 -c
check_load
OK - load average: 0.00, 0.01, 0.05|load1=0.000;15.000;30.000;0;
load5=0.010;10.000;25.000;0; load15=0.050;5.000;20.000;

But when i try to run discovery.py.i am getting error below

root at node1:~$ /usr/local/lib/nagios/plugins/gluster/discovery.py -c
vmgfstst -H 172.16.5.66

"brickaddre\n')


But when i run discover volume list command it works.
rootr at node1:~$ /usr/lib/nagios/plugins/check_nrpe -H 172.16.5.66 -c
discover_volume_list
{"vmgfsvol1": {"type": "DISTRIBUTED_DISPERSE", "name": "vmgfsvol1"}}


Looking for help to solve this issue.
