[Gluster-users] Gluster plugins for Nagios: "Volume Utilization" and "Cluster Utilization" are not working

[Mauro Tridici]

Dear All,

some year ago, I installed and configured a Gluster volume using 3 servers.
I also installed Nagios Community in order to monitor Gluster servers and services and everything works correctly.

Recently, I added 3 new servers to the existing Gluster volume and I decided to use the same Nagios server to check all services.
All services are ok except for "Volume Utilization" and "Cluster Utilization" ones.
Once a day, I receive the following messages sequence.

I'm using Nagios Core v.4.3.2.
On the first 3 servers I installed NRPE client v.3.1.1
On the new 3 servers I installed NRPE client v.3.2.0

Is there something I can do in order to correct this issue?

Thank you in advance,
Mauro
