## Description

Read events from the collectd binary protocol over the network via udp. See 
Configuration in your Logstash configuration file can be as simple as:
```
    input {
      udp {
        port => 25826
        buffer_size => 1452
        codec => collectd { }
      }
    }
```

A sample `collectd.conf` to send to Logstash might be:
```
    Hostname    "host.example.com"
    LoadPlugin interface
    LoadPlugin load
    LoadPlugin memory
    LoadPlugin network
    <Plugin interface>
        Interface "eth0"
        IgnoreSelected false
    </Plugin>
    <Plugin network>
        <Server "10.0.0.1" "25826">
        </Server>
    </Plugin>
```

Be sure to replace `10.0.0.1` with the IP of your Logstash instance.

### `authfile`

- Value type is [string](/elastic/logstash-docs-md/tree/main/lsr/value-types#string)
- There is no default value for this setting.

Path to the authentication file. This file should have the same format as the [AuthFile](http://collectd.org/documentation/manpages/collectd.conf.5.shtml#authfile_filename) in collectd. You only need to set this option if the `security_level` is set to `Sign` or `Encrypt`

### `nan_handling`

- Value can be any of: `change_value`, `warn`, `drop`
- Default value is `"change_value"`

What to do when a value in the event is `NaN` (Not a Number)
- change_value (default): Change the `NaN` to the value of the nan_value option and add `nan_tag` as a tag
- warn: Change the `NaN` to the value of the nan_value option, print a warning to the log and add `nan_tag` as a tag
- drop: Drop the event containing the `NaN` (this only drops the single event, not the whole packet)


### `nan_tag`

- Value type is [string](/elastic/logstash-docs-md/tree/main/lsr/value-types#string)
- Default value is `"_collectdNaN"`

The tag to add to the event if a `NaN` value was found Set this to an empty string ('') if you don’t want to tag

### `nan_value`

- Value type is [number](/elastic/logstash-docs-md/tree/main/lsr/value-types#number)
- Default value is `0`

Only relevant when `nan_handeling` is set to `change_value` Change NaN to this configured value

### `prune_intervals`

- Value type is [boolean](/elastic/logstash-docs-md/tree/main/lsr/value-types#boolean)
- Default value is `true`

Prune interval records. Defaults to `true`.

### `security_level`

- Value can be any of: `None`, `Sign`, `Encrypt`
- Default value is `"None"`

Security Level. Default is `None`. This setting mirrors the setting from the collectd [Network plugin](https://collectd.org/wiki/index.php/Plugin:Network)

### `typesdb`

- Value type is [array](/elastic/logstash-docs-md/tree/main/lsr/value-types#array)
- There is no default value for this setting.

File path(s) to collectd `types.db` to use. The last matching pattern wins if you have identical pattern names in multiple files. If no types.db is provided the included `types.db` will be used (currently 5.4.0).
