This module is an API-type Drupal module to help other modules expose their internal instrumentation to Munin.

The main Munin API module itself exposes few user-level features, but is used mostly as a dependency by the included sub-modules and any user-created modules.

Plugins

The Munin APC submodule exposes two APC graphs:

• a line chart of the caching information
• an area chart for APC uptime

The Munin Core submodule exposes several graphs:

• Core: users (active vs blocked), sessions (anonymous vs authenticated)
• Core content: comments (unpublished vs published), nodes (unpublished vs published)
• Core taxonomy: terms

A Munin monitoring mechanism is also built into the Munin API module.

• It exposes a graph of the interval between Munin probes
