## Unreleased / ????-??-??
|
|
|
|
* [ENHANCEMENT] Add a health check to the Docker container ([#182](https://github.com/prometheus/statsd_exporter/pull/182))
|
|
* [BUGFIX] Fix panic if a mapping resulted in an empty name ([#192](https://github.com/prometheus/statsd_exporter/pull/192))
|
|
|
|
With #192, the count of events rejected because of negative counter increments has moved into the `statsd_exporter_events_error_total` metric, instead of being lumped in with the different kinds of successful events.
|
|
|
|
## v0.9.0 / 2019-03-11
|
|
|
|
* [ENHANCEMENT] Update the Prometheus client library to 0.9.2 ([#171](https://github.com/prometheus/statsd_exporter/pull/171))
|
|
* [FEATURE] Metrics can now be expired with a per-mapping TTL ([#164](https://github.com/prometheus/statsd_exporter/pull/164))
|
|
* [CHANGE] Timers that mapped to a summary are scaled to seconds, just like histograms ([#178](https://github.com/prometheus/statsd_exporter/pull/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](https://github.com/prometheus/statsd_exporter/pull/161))
|
|
* [BUGFIX] Unsuccessful backtracking does not clobber captures ([#169](https://github.com/prometheus/statsd_exporter/pull/169), fixes [#168](https://github.com/prometheus/statsd_exporter/issues/168))
|
|
|
|
## v0.8.0 / 2018-10-12
|
|
|
|
* [ENHANCEMENT] Speed up glob matching ([#157](https://github.com/prometheus/statsd_exporter/pull/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](https://github.com/fffonion).
|
|
|
|
## 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](https://github.com/prometheus/statsd_exporter/pull/141))
|
|
* [ENHANCEMENT] Allow matching on specific metric types ([#136](https://github.com/prometheus/statsd_exporter/pulls/136))
|
|
* [ENHANCEMENT] Summary quantiles can be configured ([#135](https://github.com/prometheus/statsd_exporter/pulls/135))
|
|
* [BUGFIX] Fix panic if an invalid regular expression is supplied ([#126](https://github.com/prometheus/statsd_exporter/pulls/126))
|
|
|
|
## v0.6.0 / 2018-01-17
|
|
|
|
* [ENHANCEMENT] Add a drop action ([#115](https://github.com/prometheus/statsd_exporter/pulls/115))
|
|
* [ENHANCEMENT] Allow templating metric names ([#117](https://github.com/prometheus/statsd_exporter/pulls/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
|
|
|
|
```yaml
|
|
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](https://github.com/bakins/statsd-exporter-convert) available to help with this conversion.
|
|
|
|
* [CHANGE] Replace the overloaded "packets" metric ([#106](https://github.com/prometheus/statsd_exporter/pulls/106))
|
|
* [CHANGE] Removed `-statsd.add-suffix` option flag [#99](https://github.com/prometheus/statsd_exporter/pulls/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](https://github.com/prometheus/statsd_exporter/pulls/92). Many log events have been changed from error
|
|
to debug log level.
|
|
* [CHANGE] Use YAML for configuration file [#66](https://github.com/prometheus/statsd_exporter/pulls/66). See note above about file format
|
|
conversion.

|
* [ENHANCEMENT] Added support for sampling factor on timing events [#28](https://github.com/prometheus/statsd_exporter/pulls/28)
|
|
* [BUGFIX] Conflicting label sets no longer crash the exporter and will be
|
|
ignored. Restart to clear the remembered label set. [#72](https://github.com/prometheus/statsd_exporter/pulls/72)
|
|
|

|
|
* [BUGFIX] Increase receivable UDP datagram size to 65535 bytes ([#36](https://github.com/prometheus/statsd_exporter/pulls/36))
|
|
* [BUGFIX] Warn, not panic when negative number counter is submitted ([#33](https://github.com/prometheus/statsd_exporter/pulls/33))
|
|
|
