Check manual page of multipath
State of multipathing on Linux
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".
If the multipath device has an alias you can alternatively specify the
alias as item.
One check for each multipath device is created. Via iventory_multipath_rules
you can specify whether an alias should be used as item instead of the UUID.
