[om-infra] Fwd: Monitor is UP: OMV_gallery

Hi,
once again, some of our web services were down during about 4 hours
between midnight and 04:00 AM (UTC).

Last time, Raphaël suggested that the issue could have been due to the
backup in proxmox.
I started an investigation this morning and here are my first findings
and interrogations:
-- the robot monitors  5 web services, all hosted in jasper
-- only 3 of them was down this night
-- the backup was made on garnet
-- garnet was said to be suspended during about 30 minutes
-- the compression lasted 4 hours for 23 GiB
I have summarized the time chart in the attachment:
-- the time given has been adjusted to UTC + 1 (according to the
turquoise's time)
-- be aware that the aspect of the doc is non linear
-- for one CMS (gallery), the down time started before the compression
of the archive
-- I highlighted some warnings in the excerpt of the backup log

Finally, I'm not really sure that the backup and the down time of the
CMSes are directly connected. However, if they are, I see don't how
exactly.
The common point between the downed CMSes seems to be nginx.
More investigations are needed (the analisis of the logs).

If you have an idea, please, enlighten me :)
