title: Genuscreen: State of Carp Interfaces on Carp Clusters and Nodes
agents: snmp
catalog: hw/network/genua

distribution: check_mk
description:
 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.

perfdata:
 None

inventory:
 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.

item:
 The name of the carp interfaces
