At our company we have quite a lot of Windows 2012/2008 servers which are updated automatically (and sometimes rebooted) via SCCM. All our servers are monitored via Icinga/Nagios. If the servers are rebooted during the update process we get "false" alarms.
Our linux servers are also updated automatically (and rebooted if a new kernel was installed). We scripted our own update procedure and call a webservice to schedule downtime for the affected host. The webservice does some security and sanity checks and uses Icingas external command file to schedule the downtime.
Now, I was wondering if there's any possibility to call the webservice via SCCM during the update process? Any suggestions?
