Genuscreen: State of Carp Interfaces on Carp Clusters and Nodes

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

This check monitors the state of the carp interfaces of genuscreen devices. It can be used on single hosts as well as clusters. For the latter, the nodes of the carp cluster must be included in a Check_MK cluster, and the check must be configured as clustered service with an approriate rule. Clusters with more then two nodes are supported. The check detects if it is called on a cluster or a node. For a node the interface and carp state of the carp interface items are checked. For a cluster the check determines the number of carp interfaces on the cluster with the state master. If it is either 0 or >1 the check is critical.

The check is known to run with genuscreen version 3.0 and supports genuas regular enterprise id 3717 as well as the id 3137 which was introduced in a bug in some versions of genuscreen.

Item

The name of the carp interfaces

Discovery

The inventory process checks if the device has a system description OIDs (.1.3.6.1.2.1.1.2.0) and if the name of this OID contains "genuscreen" (case insensitive). If this is true the system is inventorized.
