Ensure daily apache2 graceful restart is splayed
We ship out a random sleep script to cron.daily to ensure that
graceful restarts from logrotation is spread out across the various
units. - 330. By Haw Loeung

Add 'Accept-Encoding' in nrpe and health checks
Upstream archives use mod_deflate which sets 'Vary: Accept-Encoding' on responses, so check_http should set that header.
This also reduces the logging spam from squid:

archive. ubuntu. com/ubuntu/ pool/' 'accept- encoding= "*"'
| 2021/03/10 00:15:00 kid1| clientProcessHit: Vary object loop!We also hope to reduce squid memory usage (mem_node) as discovered by
tcuthbert.Reviewed-on: https:/

Make health-check script/endpoint more resilient
u-r-c units are usually deployed in public clouds with the sync-host
set to the main Ubuntu archive servers. We can't control the network
connectivity/conditions so update health-check script to retry up to 3
times on failures.Reviewed-on: https:/

Don't set health-
check-disabled flag in apache. create_ metadata_ site() On non-leader units, metadata sync calls service.pause() which then
calls this. This causes a brief period where the unit is disabled and
not serving requests. It's useful for initial unit provisioning but
not so on a fully functional unit where metadata points to an existing
copy on disk.NOTE: The setting of health-
check-disabled flag was introduced in r309 (MP:398100). Reviewed-on: https:/
