Check Interfaces Operational Status

Checks the operational status of an interface list on a IF-MIB compliant network device.

Plugin let us checking the operational status of an interfaces list given. If all interfaces are UP then the plugin state is OK, if not, if almost one of the interfaces has an operational status different to UP state, plugin checks if the interface is in the warning interface list or in the critical interface list to return the plugin state.

An example should make this more clear.

check_iface_status -H 192.0.0.13 -u 1..5,8 -w 1,8 -c 2..5

In this case, plugin checks interfaces 1,2,3,4,5 and 8 of a device with address 192.0.0.13, and possible states are:

- OK, if all checked interfaces has a operational status equal to UP

- WARNING,if any of the interfaces 1 or 8 haven´t a operational status equal to UP

- CRITICAL, if any of the interfaces 2, 3, 4 or 5 haven´t a operational status equal to UP

- UNKNOWN, if it cant´s establish a SNMP connection or another undetected error.

Also, plugin can be used in test mode to know if SNMP access is enabled to your device and if it supports IF-MIB. An example of it could be:

check_iface_status -H 192.0.0.13

- OK if it passed the test. A list with the found interfaces with the id, operatinal status and description is shown too.

- UNKNOWN if test didn´t pass the test.

Plugin is fully embedded Perl compatible (ePN).
