collectd_haproxy.plugin¶collectd_haproxy.plugin.HAProxyPlugin(collectd)[source]¶Bases: object
The plugin class, workhorse that liasons between collectd and HAProxy.
Rather than being instantiated directly, the register() method should
be used to make a plugin, since it both creates an instance and takes
care of the proper callback registration.
HAProxy Plugin constructor
Since the collectd module is only available when the plugin is running in collectd’s python process we use some dependency injection here.
| Parameters: | collectd (module) – The collectd module. |
|---|
name = 'haproxy'¶register(collectd)[source]¶Registers the plugin’s callbacks with the given collectd module.
Since the collectd module is only available when the plugin is running in collectd’s python process we use some dependency injection here.
| Parameters: | collectd (module) – The collectd module. |
|---|
configure(config)[source]¶The ‘configure’ collectd callback for the plugin.
Iterates over the config object’s children attribute and sets any
applicable attributes on the plugin instance.
| Parameters: | config (collect.Config) – The collectd Config instance. Passed in automatically by collectd itself. |
|---|
initialize()[source]¶The ‘initialize’ collectd callback for the plugin.
This callback fires after the ‘config’ one but before the ‘read’ one gets added to the loop.
Instantiates a collectd.Values for each known metric (these are used
to dispatch actual values to collectd) as well as sets up the
HAProxySocket for fetching the values.
read()[source]¶The ‘read’ collectd callback for the plugin.
Simple method that calls collect_info() and/or collect_stats()
based on the configuration.
