Re: Gluster-Nagios

[Sahina Bose <sabose@xxxxxxxxxx>]

You can update the packages with the ones built from source.
You will need to update both the client and server nrpe packages with the modified payload limit to resolve this
- nagios-plugins-nrpe
- nrpe

Have you done that?

Looks like you are hitting the NRPE Payload issue. Standard NRPE packages from epel/fedora has 1024 bytes payload limit. We have to increment this to 8192 to fix this. You can see more info at http://serverfault.com/questions/613288/truncating-return-data-as-it-is-bigger-then-nrpe-allows.

Let me know if u need any more info.

The gluster-nagios packages have not been tested on Ubuntu

Looking at the error below, it looks like the rpm has not updated the nrpe.cfg correctly. You may need to edit the spec file for the config file paths on Ubuntu and rebuild.

Can you give us the version of these packages?

Dear All,

In June 2014, the gluster-nagios team (thanks!) published the availability of gluster-nagios-common and gluster-nagios-addons on this list. As far as I can tell, this quite extensive gluster nagios monitoring tool is available for el6 only. Are there known plans to make this available for el7 outside the RHEL-repos (http://ftp.redhat.de/pub/redhat/linux/enterprise/7Server/en/RHS/SRPMS/), e.g. for use with oVirt / Centos 7 also? It would be good to be able to monitor gluster without playing around with scripts from sources other than a rpm repo.

Michael
