Module: check_mk Branch: master Commit: 1577f5816924cb45259014ba92262554bf1744aa URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=1577f5816924cb… Author: Mathias Kettner &lt;mk(a)mathias-kettner.de&gt; Date: Mon Dec 8 16:08:19 2014 +0100 #1712 FIX hyper_vms: fixed for snapshot VMs with (...) in their names When restoring snapshots then HyperV creates names like <tt>VM z4058044_snap (23.05.2014 - 09:29:29)</tt>. These names had not been handled correctly by neither the agent plugin nor the check. Both has been fixed. The check is still compatible with the old agent output - and removes everying after the <tt>_snap</tt> in the VM name.
