Since we had a few PI-caused locklosses last week, we realized that the PI monitor (PIMON) didn't seem to be running properly and saving the data 524 kHz DCPD data at the end of the lock. TJ has been trying to debug the issue. In the meantime, I have left PIMON running on a control room computer that I am logged into, and the lockloss data is being saved into /ligo/gitcommon/labutils/PIMON/locklosses and the script plot_locklosses.py in /ligo/gitcommon/labutils/PIMON can be used to plot the data from the locklosses.

Fortunately, we haven't had any PI locklosses that we know of since last week. Whenever control room computers are rebooted, we need to restart the script.
