v0.9.0-rc3 / 2019-01-09

  • [ENHANCEMENT] Update the Prometheus client library to 0.9.2 (#171)
  • [FEATURE] Metrics can now be expired with a per-mapping TTL (#164)
  • [CHANGE] Timers that mapped to a summary are scaled to seconds, just like histograms (#178)

If you are using summaries, all your quantiles and _total will change by a factor of 1000. Adjust your queries and dashboards, or consider switching to histograms altogether.

v0.8.1 / 2018-12-05

  • [BUGFIX] Expose the counter for unmapped matches (#161)
  • [BUGFIX] Unsuccessful backtracking does not clobber captures (#169, fixes #168)

v0.8.0 / 2018-10-12

  • [ENHANCEMENT] Speed up glob matching (#157)

This release replaces the implementation of the glob matching mechanism, speeding it up significantly. In certain sub-optimal configurations, a warning is logged.

This major enhancement was contributed by Wangchong Zhou.

v0.7.0 / 2018-08-22

This is a breaking release, but the migration is easy: command line flags now require two dashes (--help instead of -help). The previous flag library already accepts this form, so if necessary you can migrate the flags first before upgrading.

The deprecated --statsd.listen-address flag has been removed, use --statsd.listen-udp instead.

  • [CHANGE] Switch to Kingpin for flags, fixes setting log level (#141)
  • [ENHANCEMENT] Allow matching on specific metric types (#136)
  • [ENHANCEMENT] Summary quantiles can be configured (#135)
  • [BUGFIX] Fix panic if an invalid regular expression is supplied (#126)

v0.6.0 / 2018-01-17

  • [ENHANCEMENT] Add a drop action (#115)
  • [ENHANCEMENT] Allow templating metric names (#117)

v0.5.0 / 2017-11-16

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.

  • [CHANGE] Replace the overloaded "packets" metric (#106)
  • [CHANGE] Removed -statsd.add-suffix option flag #99. Users should remove this flag when upgrading. Metrics will no longer automatically include the suffixes _timer or counter. You may need to adjust any graphs that used metrics with these suffixes.
  • [CHANGE] Reduce log levels #92. Many log events have been changed from error to debug log level.
  • [CHANGE] Use YAML for configuration file #66. See note above about file format conversion.
  • [ENHANCEMENT] Allow help text to be customized #87
  • [ENHANCEMENT] Add support for regex mappers #85
  • [ENHANCEMENT] Add TCP listener support #71
  • [ENHANCEMENT] Allow histograms for timer metrics #66
  • [ENHANCEMENT] Added support for sampling factor on timing events #28
  • [BUGFIX] Conflicting label sets no longer crash the exporter and will be ignored. Restart to clear the remembered label set. #72

v0.4.0 / 2017-05-12

  • [ENHANCEMENT] Improve mapping configuration parser #61
  • [ENHANCEMENT] Add increment/decrement support to Gauges #65
  • [BUGFIX] Tolerate more forms of broken lines from StatsD #48
  • [BUGFIX] Skip metrics with invalid utf8 #50
  • [BUGFIX] ListenAndServe now fails on exit #58

0.3.0 / 2016-05-05

  • [CHANGE] Drop _count suffix for loaded_mappings metric (#41)
  • [ENHANCEMENT] Use common's log and version packages, and add -version flag (#44)
  • [ENHANCEMENT] Add flag to disable metric type suffixes (#37)
  • [BUGFIX] Increase receivable UDP datagram size to 65535 bytes (#36)
  • [BUGFIX] Warn, not panic when negative number counter is submitted (#33)

0.2.0 / 2016-03-19

NOTE: This release renames statsd_bridge to statsd_exporter

  • [CHANGE] New Dockerfile using alpine-golang-make-onbuild base image (#17)
  • [ENHANCEMENT] Allow configuration of UDP read buffer (#22)
  • [BUGFIX] allow metrics with dashes when mapping (#24)
  • [ENHANCEMENT] add root endpoint with redirect (#25)
  • [CHANGE] rename bridge to exporter (#26)

0.1.0 / 2015-04-17

  • Initial release
