Hi, I’m getting this error message when running the generic SNMP discovery:

 

sh: /usr/lib/centreon/plugins//centreon_generic_snmp.pl: No such file or directory

 

The plugin is installed, so what’s the issue? This is a brand new install.

Hi @raw-rs,

On the monitoring server that will run the Host Discovery job, you need to install the plugin with the following command:

yum install centreon-plugin-Applications-Protocol-Snmp

 

Regards.

Thanks - that hadn’t been installed. I’ve done that now, and it appears to have found a bunch of hosts, but now i’m getting another error:

Hi @raw-rs,

It means that one or more discovered hosts did not return a value for the related SNMP OID.

Do all hosts have a defined name?

 

Regards.

No, but I added an additional mapping for the description to link to the hostname and this was enough to clear the error.
