This is the node metricset of the module munin.

Features and configurationedit

The node metricset of the munin module collects metrics from a munin node agent and sends them as events to Elastic.

---
- module: munin
  metricsets: ["node"]
  hosts: ["localhost:4949"]
  node.namespace: node
---

All metrics exposed by a single munin node will be sent in a single event, grouped by munin items, e.g:

---
"munin": {
  "node": {
    "swap": {
      "swap_in": 198609,
      "swap_out": 612629
    },
    "cpu": {
      "softirq": 680,
      "guest": 0,
      "user": 158212,
      "iowait": 71095,
      "irq": 1,
      "system": 35906,
      "idle": 1185709,
      "steal": 0,
      "nice": 1633
    }
  }
}

In principle this module can be used to collect metrics from any agent that implements the munin node protocol (http://guide.munin-monitoring.org/en/latest/master/network-protocol.html).

Limitationsedit

Currently this module only collects metrics using the basic protocol. It doesn’t support capabilities or automatic dashboards generation based on munin configuration.

Exposed fields, dashboards, indexes, etc.edit

Munin supports a great variety of plugins each of them can be used to obtain different sets of metrics. Metricbeat cannot know the metrics exposed beforehand, so no field description or dashboard is generated automatically.
