State of Multipathing on Linux
|Distribution:||official part of Check_MK|
This check monitors the state of multipath devices on Linux
hosts. For each multipath device at time of inventory the number
of paths is put into the check parameters. If later the number
of paths is less then expected, the check goes critical. So it
does if any of the paths is broken.
If the number of paths is higher than expected, the check goes
warning. A reinventory of the check might be neccessary in that
This check is based on the output of the command multipath -l as
sent by the Linux agent. It correctly deals with various subtle
differences between the available versions of the multipath tools.
The UUID of the multipath device, e.g. "360a980004334644d654a364469555a76".
Via inventory_multipath_rules you can specify wether an alias should be used
as item instead of the UUID. If the multipath device has an alias the alias will
be used as item.
One service is created for each multipath device.
