The ceph cluster degrades to HEALTH_{WARN|CRIT} when the following
default thresholds are breached:
mon data avail warn = 30
mon data avail crit = 5
- These thresholds can be conservative. It might be desirable
to change them.
- A specific common scenario is when ceph-mon units are run in lxd
containers which report the disk usage of the underlying host. The
underlying host may have its own monitoring and its own
thresholds which can lead to duplicate or conflicting alerts.
