# Example

The `wavefront` serializer translates the Telegraf metric format to the [Wavefront Data Format](https://docs.wavefront.com/wavefront_data_format.html).  

### Configuration

```toml
[[outputs.file]]
  files = ["stdout"]

  ## Use Strict rules to sanitize metric and tag names from invalid characters
  ## When enabled forward slash (/) and comma (,) will be accpeted
  # use_strict = false
  
  ## point tags to use as the source name for Wavefront (if none found, host will be used)
  # source_override = ["hostname", "address", "agent_host", "node_host"]

  ## Data format to output.
  ## 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_OUTPUT.md
  data_format = "wavefront"
```

### Metrics

A Wavefront metric is equivalent to a single field value of a Telegraf measurement.
The Wavefront metric name will be: `<measurement_name>.<field_name>`
If a prefix is specified it will be honored.
Only boolean and numeric metrics will be serialized, all other types will generate
an error.

### Example

The following Telegraf metric

```
cpu,cpu=cpu0,host=testHost user=12,idle=88,system=0 1234567890
```

will serialize into the following Wavefront metrics

```
"cpu.user" 12.000000 1234567890 source="testHost" "cpu"="cpu0"
"cpu.idle" 88.000000 1234567890 source="testHost" "cpu"="cpu0"
"cpu.system" 0.000000 1234567890 source="testHost" "cpu"="cpu0"
```
