v1.1 [unreleased]

Release Notes

Telegraf now supports two new types of plugins: processors & aggregators.
On systemd Telegraf will no longer redirect it's stdout to /var/log/telegraf/telegraf.log. On most systems, the logs will be directed to the systemd journal and can be accessed by journalctl -u telegraf.service. Consult the systemd journal documentation for configuring journald. There is also a logfile config option available in 1.1, which will allow users to easily configure telegraf to continue sending logs to /var/log/telegraf/telegraf.log.

v1.0 [2016-09-08]

Release Notes

Breaking Change The SNMP plugin is being deprecated in it's current form. There is a new SNMP plugin which fixes many of the issues and confusions of its predecessor. For users wanting to continue to use the deprecated SNMP plugin, you will need to change your config file from [[inputs.snmp]] to [[inputs.snmp_legacy]]. The configuration of the new SNMP plugin is not backwards-compatible.

Breaking Change: Aerospike main server node measurements have been renamed aerospike_node. Aerospike namespace measurements have been renamed to aerospike_namespace. They will also now be tagged with the node_name that they correspond to. This has been done to differentiate measurements that pertain to node vs. namespace statistics.

Breaking Change: users of github_webhooks must change to the new [[inputs.webhooks]] plugin.

This means that the default github_webhooks config:

# A Github Webhook Event collector
[[inputs.github_webhooks]]
  ## Address and port to host Webhook listener on
  service_address = ":1618"

should now look like:

# A Webhooks Event collector
[[inputs.webhooks]]
  ## Address and port to host Webhook listener on
  service_address = ":1618"

  [inputs.webhooks.github]
    path = "/"

Telegraf now supports being installed as an official windows service, which can be installed via > C:\Program Files\Telegraf\telegraf.exe --service install
flush_jitter behavior has been changed. The random jitter will now be evaluated at every flush interval, rather than once at startup. This makes it consistent with the behavior of collection_jitter.

Features

#1413: Separate container_version from container_image tag.
#1525: Support setting per-device and total metrics for Docker network and blockio.

v0.13 [2016-05-11]

Release Notes

Breaking change in jolokia plugin. See https://github.com/influxdata/telegraf/blob/master/plugins/inputs/jolokia/README.md for updated configuration. The plugin will now support proxy mode and will make POST requests.
New [agent] configuration option: metric_batch_size. This option tells telegraf the maximum batch size to allow to accumulate before sending a flush to the configured outputs. metric_buffer_limit now refers to the absolute maximum number of metrics that will accumulate before metrics are dropped.
There is no longer an option to flush_buffer_when_full, this is now the default and only behavior of telegraf.
Breaking Change: docker plugin tags. The cont_id tag no longer exists, it will now be a field, and be called container_id. Additionally, cont_image and cont_name are being renamed to container_image and container_name.
Breaking Change: docker plugin measurements. The docker_cpu, docker_mem, docker_blkio and docker_net measurements are being renamed to docker_container_cpu, docker_container_mem, docker_container_blkio and docker_container_net. Why? Because these metrics are specifically tracking per-container stats. The problem with per-container stats, in some use-cases, is that if containers are short-lived AND names are not kept consistent, then the series cardinality will balloon very quickly. So adding "container" to each metric will: (1) make it more clear that these metrics are per-container, and (2) allow users to easily drop per-container metrics if cardinality is an issue (namedrop = ["docker_container_*"])
tagexclude and taginclude are now available, which can be used to remove tags from measurements on inputs and outputs. See the configuration doc for more details.
Measurement filtering: All measurement filters now match based on glob only. Previously there was an undocumented behavior where filters would match based on prefix in addition to globs. This means that a filter like fielddrop = ["time_"] will need to be changed to fielddrop = ["time_*"]
datadog: measurement and field names will no longer have _ replaced by .
The following plugins have changed their tags to not overwrite the host tag:
- cassandra: host -> cassandra_host
- disque: host -> disque_host
- rethinkdb: host -> rethinkdb_host
Breaking Change: The win_perf_counters input has been changed to sanitize field names, replacing /Sec and /sec with _persec, as well as spaces with underscores. This is needed because Graphite doesn't like slashes and spaces, and was failing to accept metrics that had them. The /[sS]ec -> _persec is just to make things clearer and uniform.
Breaking Change: snmp plugin. The host tag of the snmp plugin has been changed to the snmp_host tag.
The disk input plugin can now be configured with the HOST_MOUNT_PREFIX environment variable. This value is prepended to any mountpaths discovered before retrieving stats. It is not included on the report path. This is necessary for reporting host disk stats when running from within a container.

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)

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!
#337: Jolokia plugin, thanks @saiello!

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

Bugfixes

#331: Dont overwrite host tag in redis plugin.
#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

#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.

Features

#143: InfluxDB clustering support
#181: Makefile GOBIN support. Thanks @Vye!
#203: AMQP output. Thanks @ekini!
