A webpage displaying the last 300 lock losses(*) is available at https://scientists.virgo-gw.eu/lock-losses/. For each lock loss, the webpage also shows the ITF_lock index before the lock loss, the ITF mode, the Metatron nodes involved in the lock loss, some potential causes (called issues on the webpage) of the lock loss, the earliest of these recorded issues, a link to a set of plots, and a link to the merged time-sorted Metatron logfiles.
Further information: the potential causes are obtained thanks to some custom functions that test behaviours of various channels (around 10-15 up to date). Hence, they are labelled as "potential" as one is only running a limited set of checks; the "earliest issue" is the one with the lowest GPS time associated. These are meant to help for a deeper investigation of a given lock loss.
This is a first version of this framework; comments and feedback will be more than welcome to help improve the package and make it more useful for commissioning.
(*) Defined as a Metatron node making a transition from a higher state to down or init.
