The Error:

 

My config:

 

 

 

 

 

 

The same plugin is worked fine with another server:

 

When I make an snmpwalk from Centreon to the server, I occured an error:

 

TCP-MIB::tcpConnState.10.200.10.1.443.10.200.10.1.34700 = INTEGER: established(5)
TCP-MIB::tcpConnState.0.0.0.0.1300.0.0.0.0.0 = INTEGER: listen(2)
Error: OID not increasing: TCP-MIB::tcpConnState.10.200.10.1.443.10.200.10.1.34700

Hello :)

When a plugin returns the `Cant get a single value` error, this is explained as follows: 

UNKNOWN: SNMP GET Request : Can't get a single value​
SNMP Plugins request one or several OIDs from the target devices' MIBS. When it doesn't obtain a value for one of these OIDs, it returns an UNKNOWN state to warn the user.

Frequently, the device doesn't ship the MIB or one of the OIDs the Plugin utilizes. In other words, the Plugin used is not suitable for this device.

Kind regards.
