Munin node metricset

Munin node metricset

edit

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

This is the node metricset of the module munin.

Features and configuration

edit

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).

Limitations

edit

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.

Fields

edit

For a description of each field in the metricset, see the exported fields section.
