I have a Perl script I wrote (written/used on Linux) that we run from cron for
that. It uses the Spectrum::CLI Perl module and pulls a list of all devices in
maintenance from all landscapes, checks to see if there is a notes field, and
if there is no notes field and the device has been in maintenance for more than
3 days, it removes the device from maintenance by putting it into hibernation.
For clarity, what it does:
1. Connect to MLS (configured in script) and pull a list of all landscapes
a. filter out fault-tolerant "secondary" landscapes based on precedence
b. filter out our dedicated TrapDirector landscape
2. Get a list of all devices in maintenance
3. Enrich the data for those devices (get model class, last polled time,
notes field, and hibernation status)
4. Filter out devices that we are considering "out of scope"
a. in hibernation
b. with an entry in the notes field
c. that don't have a "last polled" time
d. interfaces (no reliable way to determine "last polled" time)
e. devices in maintenance for less than 3 days
5. For any devices left, take them out of maintenance by putting them in
"Hibernation"
a. Hibernation will get them removed from Maintenance after 3 successful
polls
i. This
prevents immediate "device unreachable" alerts for devices that are offline
We run the script from cron daily. I need to review it to make sure there's no
confidential information in it, but I can probably post it shortly.

Subject: [spectrum] Removing devices from maintenance daily
We have a problem with devices/interfaces being put in maintenance, various
reasons, but mostly to stop paging, and then being forgotten.
I have a Global Collaction that collects these, so they can be more easily
seen, however I'm looking for a way to remove everything that's in this GC from
maintenance once per day (say 8:00 am).
Anyone have any ideas?
