net-mgmt/snmp4nagios 0.4_5 DragonFly

This is a plugin package for Nagios. Quoting from the snmp4nagios home page:

SNMP4Nagios is a package of Nagios plugins which use SNMP to query hosts. While some of the plugins use standard MIBs, most are designed for vendor specific agents.

Unlike other Nagios plugins, they are able to scan hosts for objects which can be monitored. They also can keep performance logs and draw plots of these using Tobias Oetiker's RRDTool.

Currently devices by Brocade, Cisco, Compaq/HP and Network Appliance as well as computers running Microsoft Windows or Net-SNMP and uninterruptable power supplies are supported.
