0.14.0 / 2020-01-10

• [CHANGE] Switch logging to go-kit (#283)
• [CHANGE] Rename existing metric for mapping cache size (#284)
• [ENHANCEMENT] Add metrics for mapping cache hits (#280)

Logs are more structured now. The fatal log level no longer exists; use --log.level=error instead. The valid log formats are logfmt and json.

The metric statsd_exporter_cache_length is now called statsd_metric_mapper_cache_length.

v0.13.0 / 2019-12-06

• [ENHANCEMENT] Support sampling factors for all statsd metric types (#264)
• [ENHANCEMENT] Support Librato and InfluxDB labeling formats (#267)

v0.12.2 / 2019-07-25

• [BUGFIX] Fix Unix socket handler (#252)
• [BUGFIX] Fix panic under high load (#253)

Thank you to everyone who reported and helped debug these issues!

v0.12.1 / 2019-07-08

• [BUGFIX] Renew TTL when a metric receives updates (#246)
• [CHANGE] Reload on SIGHUP instead of watching the file (#243)

0.11.2 / 2019-06-14

• [BUGFIX] Fix TCP handler (#235)

0.11.1 / 2019-06-14

• [ENHANCEMENT] Batch event processing for improved ingestion performance (#227)
• [ENHANCEMENT] Switch Prometheus client to promhttp, freeing the standard HTTP metrics (#233)

With #233, the exporter no longer exports metrics about its own HTTP status. These were not helpful since you could not get them when scraping fails. This allows mapping to metric names like http_requests_total that are useful as application metrics.

0.10.6 / 2019-06-07

• [BUGFIX] Fix mapping collision for metrics with different types, but the same name (#229)

0.10.5 / 2019-05-27

• [BUGFIX] Fix "Error: inconsistent label cardinality: expected 0 label values but got N in prometheus.Labels" (#224)

0.10.4 / 2019-05-20

• [BUGFIX] Revert #218 due to a race condition (#221)

0.10.3 / 2019-05-17

• [ENHANCEMENT] Reduce allocations when escaping metric names (#217)
• [ENHANCEMENT] Reduce allocations when handling packets (#218)
• [ENHANCEMENT] Optimize label sorting (#219)
