v0.10.2 [unreleased]

Release Notes

Features

Bugfixes

v0.10.1 [2016-01-27]

Release Notes

• Telegraf now keeps a fixed-length buffer of metrics per-output. This buffer defaults to 10,000 metrics, and is adjustable. The buffer is cleared when a successful write to that output occurs.
• The docker plugin has been significantly overhauled to add more metrics and allow for docker-machine (incl OSX) support. See the readme for the latest measurements, fields, and tags. There is also now support for specifying a docker endpoint to get metrics from.

v0.10.0 [2016-01-12]

Release Notes

• Linux packages have been taken out of opt, the binary is now in /usr/bin and configuration files are in /etc/telegraf
• breaking change plugins have been renamed to inputs. This was done because plugins is too generic, as there are now also "output plugins", and will likely be "aggregator plugins" and "filter plugins" in the future. Additionally, inputs/ and outputs/ directories have been placed in the root-level plugins/ directory.
• breaking change the io plugin has been renamed diskio
• breaking change plugin measurements aggregated into a single measurement.
• breaking change jolokia plugin: must use global tag/drop/pass parameters for configuration.
• breaking change twemproxy plugin: prefix option removed.
• breaking change procstat cpu measurements are now prepended with cpu_time_ instead of only cpu_
• breaking change some command-line flags have been renamed to separate words. -configdirectory -> -config-directory, -filter -> -input-filter, -outputfilter -> -output-filter
• The prometheus plugin schema has not been changed (measurements have not been aggregated).

Packaging change note:

RHEL/CentOS users upgrading from 0.2.x to 0.10.0 will probably have their configurations overwritten by the upgrade. There is a backup stored at /etc/telegraf/telegraf.conf.$(date +%s).backup.

Features

• Plugin measurements aggregated into a single measurement.
• Added ability to specify per-plugin tags
• Added ability to specify per-plugin measurement suffix and prefix. (name_prefix and name_suffix)
• Added ability to override base plugin measurement name. (name_override)

Bugfixes

• #427: zfs plugin: pool stats added. Thanks @allenpetersen!
• #428: Amazon Kinesis output. Thanks @jimmystewpot!
• #449: influxdb plugin, thanks @mark-rushakoff

Bugfixes

• #452: Elasticsearch open file handles error. Thanks @jipperinbham!

v0.2.4 [2015-12-08]

Features

• #412: Additional memcached stats. Thanks @mgresser!
• #410: Additional redis metrics. Thanks @vlaadbrain!

Bugfixes

v0.2.3 [2015-11-30]

Release Notes

• breaking change The kafka plugin has been renamed to kafka_consumer. and most of the config option names have changed. This only affects the kafka consumer plugin (not the output). There were a number of problems with the kafka plugin that led to it only collecting data once at startup, so the kafka plugin was basically non- functional.
• Plugins can now be specified as a list, and multiple plugin instances of the same type can be specified, like this:

[[inputs.cpu]]
  percpu = false
  totalcpu = true

[[inputs.cpu]]
  percpu = true
  totalcpu = false
  drop = ["cpu_time"]

• Riemann output added
• Aerospike plugin: tag changed from host -> aerospike_host

Features

• #379: Riemann output, thanks @allenj!
• #375: kafka_consumer service plugin.
• #392: Procstat plugin can now accept pgrep -f pattern, thanks @ecarreras!
• #383: Specify plugins as a list.
• #354: Add ability to specify multiple metrics in one statsd line. Thanks @MerlinDMC!

Bugfixes

• #371: Kafka consumer plugin not functioning.
• #389: NaN value panic

v0.2.2 [2015-11-18]

Release Notes

• 0.2.1 has a bug where all lists within plugins get duplicated, this includes lists of servers/URLs. 0.2.2 is being released solely to fix that bug

Bugfixes

• #377: Fix for duplicate slices in inputs.

v0.2.1 [2015-11-16]

Release Notes

• Telegraf will no longer use docker-compose for "long" unit test, it has been changed to just run docker commands in the Makefile. See make docker-run and make docker-kill. make test will still run all unit tests with docker.
• Long unit tests are now run in CircleCI, with docker & race detector
• Redis plugin tag has changed from host to server
• HAProxy plugin tag has changed from host to server
• UDP output now supported
• Telegraf will now compile on FreeBSD
• Users can now specify outputs as lists, specifying multiple outputs of the same type.

Features

• #325: NSQ output. Thanks @jrxFive!
• #318: Prometheus output. Thanks @oldmantaiter!
• #338: Restart Telegraf on package upgrade. Thanks @linsomniac!

• #364: Support InfluxDB UDP output.
• #370: Support specifying multiple outputs, as lists.
• #372: Remove gosigar and update go-dockerclient for FreeBSD support. Thanks @MerlinDMC!

• #336: Mongodb plugin should take 2 measurements.
• #351: Fix continual "CREATE DATABASE" in writes
• #360: Apply prefix before ShouldPass check. Thanks @sotfo!

v0.2.0 [2015-10-27]

Release Notes

• The -test flag will now only output 2 collections for plugins that need it
• There is a new agent configuration option: flush_interval. This option tells Telegraf how often to flush data to InfluxDB and other output sinks. For example, users can set interval = "2s" and flush_interval = "60s" for Telegraf to collect data every 2 seconds, and flush every 60 seconds.
• precision and utc are no longer valid agent config values. precision has moved to the influxdb output config, where it will continue to default to "s"
• debug and test output will now print the raw line-protocol string
• Telegraf will now, by default, round the collection interval to the nearest even interval. This means that interval="10s" will collect every :00, :10, etc. To ease scale concerns, flushing will be "jittered" by a random amount so that all Telegraf instances do not flush at the same time. Both of these options can be controlled via the round_interval and flush_jitter config options.
• Telegraf will now retry metric flushes twice

Features

• #205: Include per-db redis keyspace info
• #226: Add timestamps to points in Kafka/AMQP outputs. Thanks @ekini
• #90: Add Docker labels to tags in docker plugin

• #227: Add command intervals to exec plugin. Thanks @jpalay!
• #241: MQTT Output. Thanks @shirou!
• Memory plugin: cached and buffered measurements re-added
• Logging: additional logging for each collection interval, track the number of metrics collected and from how many inputs.
• #240: procstat plugin, thanks @ranjib!
• #244: netstat plugin, thanks @shirou!
• #262: zookeeper plugin, thanks @jrxFive!
• #237: statsd service plugin, thanks @sparrc

• #302: Fix [tags] getting applied, thanks @gotyaoi!

v0.1.9 [2015-09-22]

Release Notes

• InfluxDB output config change: url is now urls, and is a list. Config files will still be backwards compatible if only url is specified.
• The -test flag will now output two metric collections
• Support for filtering telegraf outputs on the CLI -- Telegraf will now allow filtering of output sinks on the command-line using the -outputfilter flag, much like how the -filter flag works for inputs.
• Support for filtering on config-file creation -- Telegraf now supports filtering to -sample-config command. You can now run telegraf -sample-config -filter cpu -outputfilter influxdb to get a config file with only the cpu plugin defined, and the influxdb output defined.
• Breaking Change: The CPU collection plugin has been refactored to fix some bugs and outdated dependency issues. At the same time, I also decided to fix a naming consistency issue, so cpu_percentageIdle will become cpu_usage_idle. Also, all CPU time measurements now have it indicated in their name, so cpu_idle will become cpu_time_idle. Additionally, cpu_time measurements are going to be dropped in the default config.
• Breaking Change: The memory plugin has been refactored and some measurements have been renamed for consistency. Some measurements have also been removed from being outputted. They are still being collected by gopsutil, and could easily be re-added in a "verbose" mode if there is demand for it.

• #143: InfluxDB clustering support
