-
-# This script provides an example of a PVC monitoring plugin script. It will create
-# a simple plugin to check the Ceph cluster health for anomalies, and return a health
-# delta reflective of the overall Ceph status (HEALTH_WARN = 10, HEALTH_ERR = 50).
-
-# This script can thus be used as an example or reference implementation of a
-# PVC monitoring pluginscript and expanded upon as required.
-
-# A monitoring plugin script must implement the class "MonitoringPluginScript" which
-# extends "MonitoringPlugin", providing the 3 functions indicated. Detailed explanation
-# of the role of each function is provided in context of the example; see the other
-# examples for more potential uses.
-
-# WARNING:
-#
-# This script will run in the context of the node daemon keepalives as root.
-# DO NOT install untrusted, unvetted plugins under any circumstances.

-
-# This import is always required here, as MonitoringPlugin is used by the
-# MonitoringPluginScript class

-# A monitoring plugin script must always expose its nice name, which must be identical to
