summary: Implementation of the Munin node protocol

...

Summary

=======

This module implements the Munin reporting protocol, allowing you to

collect statistics directly from Prosody into Munin.

Configuration

=============

There is only one recommended option, `munin_node_name`, which specifies

the name that Prosody will identify itself by to the Munin server. You

may want to set this to the same hostname as in the [SRV record][doc:dns]

for the machine.

```lua

modules_enabled = {

    -- your other modules

    "munin",

}

munin_node_name = "xmpp.example.com"

```

## Summary

All these must be in [the global section][doc:configure#overview].

  Option                  Type     Default

  ----------------------- -------- ---------------------------

  munin\_node\_name       string   `"localhost"`

  munin\_ignored\_stats   set      `{ }`

  munin\_ports            set      `{ 4949 }`

  munin\_interfaces       set      `{ "0.0.0.0", "::" }`[^1]

[^1]: Varies depending on availability of IPv4 and IPv6

## Ports and interfaces

`mod_munin` listens on port `4949` on all local interfaces by default.

This can be changed with the standard [port and network configuration][doc:ports]:

``` lua

-- defaults:

munin_ports = { 4949 }

munin_interfaces = { "::", "0.0.0.0" }

```

If you already have a `munin-node` instance running, you can set a

different port to avoid the conflict.

## Configuring Munin

Simply add `munin_node_name` surrounded by brackets to `/etc/munin/munin.conf`:

``` ini

[xmpp.example.com]

address xmpp.example.com

port 4949

```

You can leave out `address` if it equal to the name in brackets, and

leave out the `port` if it is the default (`4949`).

Setting `address` to an IP address may sometimes be useful as the Munin

collection server is not delayed by DNS lookups in case of network

issues.

If you set a different port, or if the hostname to connect to is

different from this hostname, make sure to add `port` and/or `address`

options.

See [Munin documentation][muninconf] for more information.

Compatibility

=============

**Requires** Prosody 0.10 or above
