Carbon2

The carbon2 serializer translates the Telegraf metric format to the Carbon2 format.

Configuration

[[outputs.file]]
  ## Files to write to, "stdout" is a specially handled file.
  files = ["stdout", "/tmp/metrics.out"]

  ## 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 = "carbon2"

Standard form:

metric=name field=field_1 host=foo  30 1234567890
metric=name field=field_2 host=foo  4 1234567890
metric=name field=field_N host=foo  59 1234567890

Metrics

The serializer converts the metrics by creating intrinsic_tags using the combination of metric name and fields. So, if one Telegraf metric has 4 fields, the carbon2 output will be 4 separate metrics. There will be a metric tag that represents the name of the metric and a field tag to represent the field.

Example

If we take the following InfluxDB Line Protocol:

weather,location=us-midwest,season=summer temperature=82,wind=100 1234567890

after serializing in Carbon2, the result would be:

metric=weather field=temperature location=us-midwest season=summer  82 1234567890
metric=weather field=wind location=us-midwest season=summer  100 1234567890

Fields and Tags with spaces

When a field key or tag key/value have spaces, spaces will be replaced with _.

Tags with empty values

When a tag's value is empty, it will be replaced with null
