statsd_exporter/CHANGELOG.md

v 0.5.0 / 2017-11-14

NOTE: This release breaks backward compatibility. statsd_exporter now uses a YAML configuration file. You must convert your mappings configuration to the new format when you upgrade. For example, the configuration

test.dispatcher.*.*.*
name="dispatcher_events_total"
processor="$1"
action="$2"
outcome="$3"
job="test_dispatcher"

*.signup.*.*
name="signup_events_total"
provider="$2"
outcome="$3"
job="${1}_server"

now has the format

mappings:
- match: test.dispatcher.*.*.*
  help: "The total number of events handled by the dispatcher."
  name: "dispatcher_events_total"
  labels:
    processor: "$1"
    action: "$2"
    outcome: "$3"
    job: "test_dispatcher"
- match: *.signup.*.*
  name: "signup_events_total"
  help: "The total number of signup events."
  labels:
    provider: "$2"
    outcome: "$3"
    job: "${1}_server"

The help field is optional.

There is a tool available to help with this conversion.
