UCS Bladecenter: Fibrechannel, Ethernet and Interconnect Interfaces

Distribution: official part of Check_MK
License: GPL
Supported Agents: AGENT_UCS_BLADECENTER

This check monitors the operational status, link speed, traffic, packet counts, discards and errors of the ethernet, fibrechannel and interconnect interfaces of UCS Bladecenters. Each of these interfaces can be grouped in portchannels. If an interface is grouped in a portchannel, a grouped interface service will be created automatically and the single interface is not displayed.

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 1 GBit/s operates only at 100 MBit/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 time range 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-interface base. Interfaces with averaging turned on yield two additional performance values: the averaged in- and outgoing traffic in bytes. If you have configured traffic levels, then those levels are applied to the averaged values.

Item

There are three allowed ways to specify an interface: its index, which simply enumerates the interfaces, its description and its alias. For this check, the description and the alias are the same. Furthermore, it is highly recommended to use the description in the item name for this check (rule "Network interface and switch port discovery"), since contrary to the index, it allows for identifying the corresponding port.

Discovery

One service is created for each interface that fulfills configurable conditions (rule "Network interface and switch port discovery"). By default, these are interfaces which are currently found up and are of type 6, 32, 62, 117, 127, 128, 129, 180, 181, 182, 205 or 229. Note that all interfaces discovered by this check are of type 6.

Grouping: In some situations, you do not want to monitor a single interface but a group of interfaces that together form a pool. This check supports such pools by defining groups. The data of all members is accumulated and put together in a single grouped interface service.
