# This module adds compatibility with the nrpe-external-master and plain nrpe
|
||||
# subordinate charms. To use it in your charm:
|
||||
#
|
||||
# 1. Update metadata.yaml
|
||||
#
|
||||
# provides:
|
||||
# (...)
|
||||
# nrpe-external-master:
|
||||
# interface: nrpe-external-master
|
||||
# scope: container
|
||||
#
|
||||
# and/or
|
||||
#
|
||||
# provides:
|
||||
# (...)
|
||||
# local-monitors:
|
||||
# interface: local-monitors
|
||||
# scope: container
|
||||
|
||||
#
|
||||
# 2. Add the following to config.yaml
|
||||
#
|
||||
# nagios_context:
|
||||
# default: "juju"
|
||||
# type: string
|
||||
# description: |
|
||||
# Used by the nrpe subordinate charms.
|
||||
# A string that will be prepended to instance name to set the host name
|
||||
# in nagios. So for instance the hostname would be something like:
|
||||
# juju-myservice-0
|
||||
# If you're running multiple environments with the same services in them
|
||||
# this allows you to differentiate between them.
|
||||
# nagios_servicegroups:
|
||||
# default: ""
|
||||
# type: string
|
||||
# description: |
|
||||
# A comma-separated list of nagios servicegroups.
|
||||
# If left empty, the nagios_context will be used as the servicegroup
|
||||
#
|
||||
# 3. Add custom checks (Nagios plugins) to files/nrpe-external-master
|
||||
#
|
||||
# 4. Update your hooks.py with something like this:
|
||||
#
|
||||
# from charmsupport.nrpe import NRPE
|
||||
# (...)
|
||||
# def update_nrpe_config():
|

Functions for managing volumes in juju units. One volume is supported per unit.

type: boolean
|

default: true
|

description: >
|
||||
If false, a volume is mounted as sepecified in "volume-map"
|
||||
If true, ephemeral storage will be used, meaning that log data
|

will only exist as long as the machine. YOU HAVE BEEN WARNED.

YAML map of units to device names, e.g:

"{ rsyslog/0: /dev/vdb, rsyslog/1: /dev/vdb }"
|

Service units will raise a configure-error if volume-ephemeral
