# Collectd
|
|
|
|
|
|
|
|
|
|
The collectd format parses the collectd binary network protocol. Tags are
|
|
|
|
|
created for host, instance, type, and type instance. All collectd values are
|
|
|
|
|
added as float64 fields.
|
|
|
|
|
|
|
|
|
|
For more information about the binary network protocol see
|
|
|
|
|
[here](https://collectd.org/wiki/index.php/Binary_protocol).
|
|
|
|
|
|
|
|
|
|
You can control the cryptographic settings with parser options. Create an
|
|
|
|
|
authentication file and set `collectd_auth_file` to the path of the file, then
|
|
|
|
|
set the desired security level in `collectd_security_level`.
|
|
|
|
|
|
|
|
|
|
Additional information including client setup can be found
|
|
|
|
|
[here](https://collectd.org/wiki/index.php/Networking_introduction#Cryptographic_setup).
|
|
|
|
|
|
|
|
|
|
You can also change the path to the typesdb or add additional typesdb using
|
|
|
|
|
`collectd_typesdb`.

### Configuration
|
|
|
|
|
|
|
|
|
|
```toml

|
|
|
[[inputs.socket_listener]]
|
|
|
|
|

## Data format to consume.
|
|
|
|
|
## Each data format has its own unique set of configuration options, read
|
|
|
|
|
## more about them here:
|
|
|
|
|
## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
|
|
|
|
|
data_format = "collectd"
|
|
|
|
|
|
|
|
|
|
## Authentication file for cryptographic security levels
|
|
|
|
|
collectd_auth_file = "/etc/collectd/auth_file"
|
|
|
|
|
## One of none (default), sign, or encrypt
|
|
|
|
|
collectd_security_level = "encrypt"
|
|
|
|
|
## Path of to TypesDB specifications
|
|
|
|
|
collectd_typesdb = ["/usr/share/collectd/types.db"]
|
|
|
|
|
|
|
|
|
|
## Multi-value plugins can be handled two ways.
|
|
|
|
|
## "split" will parse and store the multi-value plugin data into separate measurements
|
|
|
|
|
## "join" will parse and store the multi-value plugin as a single multi-value measurement.
|
|
|
|
|
## "split" is the default behavior for backward compatability with previous versions of influxdb.
|
|
|
|
|
collectd_parse_multivalue = "split"
|
|
|
|
|
```
