Need a sanity check with pdu plug-in
Posted: Thu Jul 30, 2015 1:14 pm
Hoping to get another pair of eyes on this as I am a struggling to figure this one out. I recently added an APC PDU load script from https://exchange.nagios.org/directory/P ... s#rev-1648 to my Nagios Xi installation and am having trouble getting it to work. After several failed command and service configuration tests, I decided to look at the script's code to see where the potential hang up could be. Here is the script's code.
Having read through this, I am under the impression that this plugin only supports SNMPv2c calls to the target devices. Am I correct in this assessment? It certainly would explain why I am unable to pull a response from my PDUs as they only support SNMPv1 and v3. Thanks in advance for your help.
