sysUpTime or sysDescr isn't detected properly #211

Closed mrgohin closed 3 years ago

mrgohin commented 5 years ago

Hello,

It seems like that on some devices the sysDescr parsing / detection is failing.

On a HP 5400R nwc_health is reporting for example:

# ./check_nwc_health --hostname * --community * --mode interface-usage --report short
UNKNOWN - got neither sysUptime nor sysDescr, is this snmp agent working correctly?

and with super verbose (correct me whatever the correct name is):

If I run a snmpwalk against the same switch:

# snmpbulkwalk -t 15 -r 20 -ObentU -v2c -c public * system

I'd wish I could just provide a Pull Request, but I'm not aware of where this detection process is happening. My Guess is that GL Plugins got it hands on it...
