Operational Status of Network Interfaces - DEPRECATED

Distribution: official part of Check_MK
License: GPL
Supported Agents: SNMP

This check polls the SNMP OID . (IF-MIB::ifOperStatus) which is part of the standard SNMP interfaces MIB. It checks network interfaces for their operational status (the link). The link can either be 'up' or 'down'. The check status is OK if the actual link status is equal to the target status. If the target status is 'up' and the link status is 'down', the check gets CRITICAL. If the link status is 'up' and the target status is 'down', the check gets into WARNING status.


A string: the name of the interface as in . (IF-MIB::ifDescr). The OID index is not relevant.


One service is created for each interfaces if it is of the correct type (default is ethernetCsmacd).
