I am having problems with Maintenance Windows. Our I.T.
department has the "potential" to work on servers between
midnight and 4AM. To prevent an avalanche of emails to the
Programmers and Designers, I setup a daily maintenence window for this
time frame. Immediately afterwards we began noticing that it was
affecting our up-time SLAs even if the server or service never went
down. In fact, during a maintenance window, all monitoring of
the server or service stops! After a support chat, I was told to
turn on the setting that maintenance windows will show as UP. I
did that and it did show as UP, but the monitoring is still ignored
during that time frame.
I then went into edit on a User, Alert Settings to see if I could
change the Alerting Period to be 4AM to Midnight. Turns out that
you cannot turn off Email alerts via the Alerting Period slider!
Isn't that the whole point of setting the Alerting Period
for a person?
At this point, I have to remove all the Maintenance Windows so
that the true monitoring will continue to work correctly because
either the Maintenance Window function is broken, or the Alerting
Period function is broken. Take your pick.
Honestly, I would like to see maintenance windows continue to
monitor devices and servers for SLA purposes, and ideally both of
these features should be fixed.
