Seismic blrms displaying one hour
I just noticed a chat message from Erik that there was only one hour of Seismic blrms data being displayed in the control room. This has to do with the fact that after h1dmt1 was restarted there was only 1 hour of trend data available in the last 48 hours due to the mis-mounting of the /gds trends directory. The trend files are now available back to yesterday afternoon, so a restart of the blrms monitors should expand the displayed data to at least 16 hours. I tried to contact the control room via teamspeak, but I did not get a reply. I will wait until the control room is manned to restart the blrms monitors. This should have no effect other than to cause the blrms monitor displays to update.
I have just restarted the Seismic monitors after clearing it with the control room. At present there should be 21 hours of data being displayed which corresponds to the amount of trend data that have been stored since the /gds mount was fixed (h1dmt1 was restarted). I don't see any problematic side effects. To get the full 48 hour history, we will have to restart the seismic monitors again once the trends have been written for 48 hours (tomorrow afternoon PDT).
