# Wavefront Output Plugin
|
||||
|
||||
This plugin writes to a [Wavefront](https://www.wavefront.com) proxy, in Wavefront data format over TCP.
|
||||
|
||||
|
||||
### Configuration:
|
||||
|
||||
```toml
|
||||
# Configuration for Wavefront output
|
||||
[[outputs.wavefront]]
|
||||
## DNS name of the wavefront proxy server
|
||||
host = "wavefront.example.com"
|
||||
|
||||
## Port that the Wavefront proxy server listens on
|
||||
port = 2878
|
||||
|
||||
## prefix for metrics keys
|
||||
#prefix = "my.specific.prefix."
|
||||
|
||||
## wether to use "value" for name of simple fields. default is false
|
||||
#simple_fields = false
|
||||
|
||||
## character to use between metric and field name. default is . (dot)
|
||||
#metric_separator = "."
|
||||
|
||||
## Convert metric name paths to use metricSeperator character
|
||||
## When true will convert all _ (underscore) chartacters in final metric name. default is true
|
||||
#convert_paths = true
|
||||
|
||||
## Use Regex to sanitize metric and tag names from invalid characters
|
||||
## Regex is more thorough, but significantly slower. default is false
|
||||
#use_regex = false
|
||||
|
||||
## point tags to use as the source name for Wavefront (if none found, host will be used)
|
||||
#source_override = ["hostname", "snmp_host", "node_host"]
|
||||
|
||||
## whether to convert boolean values to numeric values, with false -> 0.0 and true -> 1.0. default is true
|
||||
#convert_bool = true
|
||||
|
||||
## Define a mapping, namespaced by metric prefix, from string values to numeric values
|
||||
## The example below maps "green" -> 1.0, "yellow" -> 0.5, "red" -> 0.0 for
|
||||
## any metrics beginning with "elasticsearch"
|
||||
#[[outputs.wavefront.string_to_number.elasticsearch]]
|
||||
# green = 1.0
|
||||
# yellow = 0.5
|
||||
# red = 0.0
|
||||
```
|
||||
|
||||
|
||||
### Convert Path & Metric Separator
|
||||
If the `convert_path` option is true any `_` in metric and field names will be converted to the `metric_separator` value.
|
||||
By default, to ease metrics browsing in the Wavefront UI, the `convert_path` option is true, and `metric_separator` is `.` (dot).
|
||||
Default integrations within Wavefront expect these values to be set to their defaults, however if converting from another platform
|
||||
it may be desirable to change these defaults.
|
||||
|
||||
|
||||
### Use Regex
|
||||
Most illegal characters in the metric name are automatically converted to `-`.
|
||||
The `use_regex` setting can be used to ensure all illegal characters are properly handled, but can lead to performance degradation.
|
||||
|
||||
|
||||
### Source Override
|
||||
Often when collecting metrics from another system, you want to use the target system as the source, not the one running Telegraf.
|
||||
Many Telegraf plugins will identify the target source with a tag. The tag name can vary for different plugins. The `source_override`
|
||||
option will use the value specified in any of the listed tags if found. The tag names are checked in the same order as listed,
|
||||
and if found, the other tags will not be checked. If no tags specified are found, the default host tag will be used to identify the
|
||||
source of the metric.
|
||||
|
||||
|
||||
### Wavefront Data format
|
||||
The expected input for Wavefront is specified in the following way:
|
||||
```
|
||||
<metric> <value> [<timestamp>] <source|host>=<soureTagValue> [tagk1=tagv1 ...tagkN=tagvN]
|
||||
```
|
||||
More information about the Wavefront data format is available [here](https://community.wavefront.com/docs/DOC-1031)
|
||||
|
||||
|
||||
### Allowed values for metrics
|
||||
Wavefront allows `integers` and `floats` as input values. It will ignore most `strings`, but when configured
|
||||
will map certain `strings` to numeric values. By default it also maps `bool` values to numeric, false -> 0.0,
|
||||
true -> 1.0
