State of network interfaces on AIX hosts
|Distribution:||official part of Check_MK|
This check monitors the operational status, link speed, traffic, packet
counts, and errors of network interfaces of AIX hosts using
data sent by the Check_MK agent. It is fully compatible with if and
if64 and shares all of its features, including Perf-O-Meter, averaging,
flexible configuration and NagVis weathermaps.
Depending on the check parameters 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 exceeds configurable limits.
This check supports averaging the in- and outgoing traffic over a configurable
range of time by using an exponentially weighted moving average.
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. Check_MK does not check for uniqueness.
The inventory creates one service for each port that fulfills configurable conditions.
Per default these are ports which are currently found up and are of types 6 (ethernetCsmacd),
32 (frameRelay) or 117 (gigabitEthernet).
Grouping: In some situations you do not want to monitor a single
interface but a group of interfaces that together form a pool.
The if check supports such pools by defining groups.
You can specifiy the members of a group by their port type and the item name(s) of
the single interfaces. The data of all members is accumulated and put together
in a single grouped interface service.
You can specify the groups with the ruleset if_groups.
Groups are defined as list of dictionaries.
The keys are:
"name": String. Name of the group within the service description
"iftype": Integer. Interface port type as integer
"include_items": List of Strings. Interface item name. This name depends
on further settings like if_inventory_uses_alias or if_inventory_uses_description
"single"(optional): Bool. Interfaces in this group do not show up
as single service if "single" is set to True (Default: False)
For example: if_groups = (["name" : "Group WLAN", "iftype" : 6, "single" : True], ["lan"], ALL_HOSTS )
