For the past couple of days, the summary pages have shown minute trend data disappear at 12:00 UTC (05:00 AM local time). This seems to be the case for all channels that we plot, see e.g. https://nodus.ligo.caltech.edu:30889/detcharsummary/day/20150724/ioo/. Using Dataviewer, Koji has checked that indeed the frames seem to have disappeared from disk. The data come back at 24 UTC (5pm local). Any ideas why this might be?
- The data transfers to LDAS had been shut off while we were doing the DAQ debugging. I don't know if they have been turned back on. Unlikely this is the problem since you would probably see no data at all if this were the case.
- wiper script parameters might have been changed to store less of the trend data for some reason.
- Frame size is different and therefore wiper script parameters need to be adjusted.
- Steve deleted it all.
