- **list \[node\]**

  list available plugins for host. If no hostname is specified, list plugins on host running munin-node

- **nodes**

  List nodes that has plugins in this munin-node.

- **config \<plugin\>**

  output plugin configuration

- **fetch \<plugin\>**

  output plugin values

- **version**

  Print versionstring

- **quit**

  disconnect

### Plugins

These plugins can be in you language of choice: bash, perl, python, C. The plugins can be run in two modes: with and without the "config"-parameter. When run with "config" as parameter, the plugin should output the configuration of the graph. When run without parameters, the plugin should output just values

```
        # /etc/munin/plugins/load config
        host_name
        graph_title Load average
        graph_args --base 1000 -l 0
        graph_vlabel load
        load.label load
        load.draw LINE2
        load.warning 10
