HP-UX: Network Interfaces
|Distribution:||official part of Check_MK|
This uses the output of the section hpux_if sent by the HP-UX
agent of Checkmk. This uses the command nwmgr -g --st mib -c $nic
in order to get status and statistics of a network interface.
In all other aspects this check behaves identical to if and if64
(with respect to check parameters, performance data and configuration).
Note: This check does not use SNMP.
Depending on the check paramters this check can go WARN or CRIT when the
port status changes (i.e. is down), when the link speed changes (e.g. a
port expected to be set to 1GBit/s operates only at 100MBit/s), when the
absolute or procentual traffic of a port exceeds certain levels or if the
rate of errors or discards exceeds configurable limits.
As of Checkmk version 1.1.9i1 this check supports averaging the in- and
outgoing traffic over a configurable range of time by using an exponentially
weighted moving average - just as Linux does for the CPU load averages.
The averaging can be configured on a per host and per port base. This is
done by adding a key "average" to the parameter dictionary with the number
of minutes that the average should cover as its key. Port with averaging
turned on output two additional performance values: the averaged traffic
in bytes. If you have configured traffic levels, then those levels are
applied to the averaged values.
There are three allowed ways to specify a port: 1: the last component of
the SNMP OID number (as string), the ifDescr of the port or the ifAlias of
the port. If you are using the alias, you have to make sure that it is unique
by configuring useful aliases in the switch. Checkmk does not check for uniqueness.
One service is created for each NIC found on the system.
NICs are assumed to be of type 6 (Ethernet).
