McData FibreChannel Switches: Traffic and Status of Ports
This check monitors the operational status, link speed, traffic, frame
counts, C3 discards and CRC errors of FibreChannel port of McData FC switches.
This check uses the internal logic of the if/if64 check, so at some places
the naming conventions are a bit unusual (instead of frames, the check speaks
of packages, for example). The advantage of this approach is, on the other
hand, that this check makes use of all interesting features if if, such
as averaging, nice PNP templates, Perf-O-Meters and other stuff.
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 2GBit/s operates only at 1GBit/s), when the
absolute or procentual traffic of a port exceeds certain levels or if the
rate of errors or discards 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 - 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.
The port index as two digit string, for example "03" or "24". The first
port has the number "01".
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). This check announces the port
type of 6 for the FC ports. This is not exactly correct but makes the inventory
find the FC ports without further configuration.
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 )
