FAQ​
Why do I get the following error message:​
UNKNOWN: SNMP GET Request : Timeout​
This message generally means that you are not using the right SNMP version or community. It could also indicate that a third-party device like a firewall is blocking the SNMP UDP/161 request.
UNKNOWN: SNMP GET Request : Cant get a single value.​
This error message often refers to the following issues:
- the Nimble device doesn't support the MIB used by the plugin
- the targeted SNMP OID cannot be fetched because of insufficient privileges on the device
