BRS Drift Trends -- Monthly

Closes FAMIS38811, last checked in alog87797.

We can see yesterdays outage on every plot as expected and the BRS issues from October 21st. There's doesn't look to be any trend in the driftmon, and ETMY looks to be still slowly increasing in temperature before the outage. The aux plot looks about the same as during the last check except for ETMY DAMP CTL looks to have come back at a different lower spot but the EY SEI configuration looks like is not quite fully recovered so that may be why.
