Health checks

Overview
|
|
========
|
|
|
|
There is a finite set of possible health messages that a Ceph cluster can
|
|
raise -- these are defined as *health checks* which have unique identifiers.
|
|
|
|
The identifier is a terse pseudo-human-readable (i.e. like a variable name)
|
|
string. It is intended to enable tools (such as UIs) to make sense of
|
|
health checks, and present them in a way that reflects their meaning.
|
|
|
|
This page lists the health checks that are raised by the monitor and manager
|
|
daemons. In addition to these, you may also see health checks that originate
|
|
from MDS daemons (see :doc:`/cephfs/health-messages`), and health checks
|
|
that are defined by ceph-mgr python modules.
