WARNING!!
Monasca is now deployed via Ansible. This project is no longer maintained and may be out of date. It will be moved to the StackForge attic soon.
cookbook-monasca-agent
Overview
This cookbook installs and configures the Monasca Monitoring Agent
Data Bags
For use with configuration, the monasca_agent data bag contains parameters
for interfacing with the Monitoring API, global dimensions (a set of
comma-delimited name:value pairs to be included in the Agent metrics),
and logging levels.
Example
{
"id": "monasca_agent",
"keystone_url": "http://192.168.10.4:5000/v2.0",
"username": "joe_user",
"password": "correcthorsebatterystaple",
"project_name": "worldpeace",
"monasca_api_url": "http://192.168.10.4:8080/v2.0",
"service": "mini-mon"
}
Recipes
default
The default recipe sets up the Monitoring Agent and runs mon-setup to configure.
plugin_cfg
monasca-agent plugins are configured in /etc/monasca-agent/conf.d/ as YAML files ending
in .yaml which are created by this recipe. The Agent will walk through these
files when the Collector (/usr/local/bin/monasca-collector) starts. The name of
the file must match a Python plugin in /etc/monasca-agent/checks.d/ or
/usr/local/lib/python2.7/dist-packages/monagent/collector/checks_d/
conf.d/file:process.yamlchecks_d/file:process.py- data bag item:
node.default[:monasca_agent][:plugin][:process]
The .yaml files are comprised of two different sections, init_config
containing global configuration parameters, and 'instances' containing one or
more stanzas containing details about the particular check to run. These are
defined in
node.default[:monasca_agent][:plugin][:process][:init_config]
and
node.default[:monasca_agent][:plugin][:process][:instances]
respectively.
The nagios_wrapper is a special case in the plugin_cfg recipe in that
if the check is defined, the dependent package nagios-plugins-basic is
installed to provide many standard Nagios plugins.
Attributes
default
These are global attributes for use with the agent.conf file and installation settings.
With the case of dimensions, default['monasca-agent']['dimensions'] = nil appends
to the list of dimensions, if any, specified in the monasca_agent data bag.
network
These attributes configure the network plugin.
plugin_config_basenode
These attributes configure a basic set of plugins to be installed on every instance. These are in addition to the Monitoring Agent's existing set of basic metrics, listed on the monasca-agent wiki
Templates
agent.conf.erb
This is the primary configuration file for the Agent, in /etc/monasca-agent/agent.conf
plugin_yaml.erb
This template provides the basis for plugin .yaml configuration files.
