## v1.9 [2018-11-20]

#### Release Notes

- The `http_listener` input plugin has been renamed to `influxdb_listener` and
  use of the original name is deprecated.  The new name better describes the
  intended use of the plugin as a InfluxDB relay.  For general purpose
  transfer of metrics in any format via HTTP, it is recommended to use
  `http_listener_v2` instead.

- Input plugins are no longer limited from adding metrics when the output is
  writing, and new metrics will move into the metric buffer as needed.  This
  will provide more robust degradation and recovery when writing to a slow
  output at high throughput.

  To avoid over consumption when reading from queue consumers: `kafka_consumer`,
  `amqp_consumer`, `mqtt_consumer`, `nats_consumer`, and `nsq_consumer` use
  the new option `max_undelivered_messages` to limit the number of outstanding
  unwritten metrics.

## v1.7 [2018-06-12]

### Release Notes

- The `cassandra` input plugin has been deprecated in favor of the `jolokia2`
  input plugin which is much more configurable and more performant.  There is
  an [example configuration](./plugins/inputs/jolokia2/examples) to help you
  get started.

- For plugins supporting TLS, you can now specify the certificate and keys
  using `tls_ca`, `tls_cert`, `tls_key`.  These options behave the same as
  the, now deprecated, `ssl` forms.

## v1.6 [2018-04-16]

### Release Notes

- The `mysql` input plugin has been updated fix a number of type convertion
  issues.  This may cause a `field type error` when inserting into InfluxDB due
  the change of types.

  To address this we have introduced a new `metric_version` option to control
  enabling the new format.  For in depth recommendations on upgrading please
  reference the [mysql plugin documentation](./plugins/inputs/mysql/README.md#metric-version).

  It is encouraged to migrate to the new model when possible as the old version
  is deprecated and will be removed in a future version.

- The `postgresql` plugins now defaults to using a persistent connection to the database.
  In environments where TCP connections are terminated the `max_lifetime`
  setting should be set less than the collection `interval` to prevent errors.

- The `sqlserver` input plugin has a new query and data model that can be enabled
  by setting `query_version = 2`.  It is encouraged to migrate to the new
  model when possible as the old version is deprecated and will be removed in
  a future version.

- An option has been added to the `openldap` input plugin that reverses metric
  name to improve grouping.  This change is enabled when `reverse_metric_names = true`
  is set.  It is encouraged to enable this option when possible as the old
  ordering is deprecated.

- The new `http` input configured with `data_format = "json"` can perform the
  same task as the, now deprecated, `httpjson` input.

### Release Notes

- In the `kinesis` output, use of the `partition_key` and
  `use_random_partitionkey` options has been deprecated in favor of the
  `partition` subtable.  This allows for more flexible methods to set the
  partition key such as by metric name or by tag.

- With the release of the new improved `jolokia2` input, the legacy `jolokia`
  plugin is deprecated and will be removed in a future release.  Users of this
  plugin are encouraged to update to the new `jolokia2` plugin.

- In the `postgresql` and `postgresql_extensible` plugins, the type of the oid
  data type has changed from string to integer.  It is recommended to drop
  affected fields until a new shard is started. For details on how to
  workaround this issue please see [#3622](https://github.com/influxdata/telegraf/issues/3622).

  supporting Kafka 0.8 and below is available as the `kafka_consumer_legacy`
  plugin.

- In the `aerospike` input the `node_name` field has been changed to be a tag
  for both the `aerospike_node` and `aerospike_namespace` measurements.

- The default prometheus_client port has been changed to 9273.

## v1.3 [2017-05-15]

### Release Notes

- Users of the windows `ping` plugin will need to drop or migrate their
measurements in order to continue using the plugin. The reason for this is that
the windows plugin was outputting a different type than the linux plugin. This
made it impossible to use the `ping` plugin for both windows and linux
machines.

- Ceph: the `ceph_pgmap_state` metric content has been modified to use a unique field `count`, with each state expressed as a `state` tag.

Telegraf < 1.3:

```
# field_name             value
active+clean             123
active+clean+scrubbing   3
```

Telegraf >= 1.3:

```
# field_name    value       tag
count           123         state=active+clean
count           3           state=active+clean+scrubbing
```

- The [Riemann output plugin](./plugins/outputs/riemann) has been rewritten
and the previous riemann plugin is _incompatible_ with the new one. The reasons
for this are outlined in issue [#1878](https://github.com/influxdata/telegraf/issues/1878).
The previous riemann output will still be available using
`outputs.riemann_legacy` if needed, but that will eventually be deprecated.
It is highly recommended that all users migrate to the new riemann output plugin.

- Generic [socket_listener](./plugins/inputs/socket_listener) and
[socket_writer](./plugins/outputs/socket_writer) plugins have been implemented
for receiving and sending UDP, TCP, unix, & unix-datagram data. These plugins
will replace udp_listener and tcp_listener, which are still available but will
be deprecated eventually.

in their config file.

- The StatsD plugin will also no longer save it's state on a service reload.
Essentially we have reverted PR [#887](https://github.com/influxdata/telegraf/pull/887).
The reason for this is that saving the state in a global variable is not
thread-safe (see [#1975](https://github.com/influxdata/telegraf/issues/1975) & [#2102](https://github.com/influxdata/telegraf/issues/2102)),
and this creates issues if users want to define multiple instances
of the statsd plugin. Saving state on reload may be considered in the future,
but this would need to be implemented at a higher level and applied to all
plugins, not just statsd.

## v1.1.0 [2016-11-07]

### 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](https://github.com/influxdata/telegraf/blob/master/etc/telegraf.conf#L70)
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](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/snmp)
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`.

- postgresql plugins now handle oid and name typed columns seamlessly, previously they were ignored/skipped.

### Features

- [#1617](https://github.com/influxdata/telegraf/pull/1617): postgresql_extensible now handles name and oid types correctly.

## v0.13.1 [2016-05-24]

### Release Notes

- net_response and http_response plugins timeouts will now accept duration
strings, ie, "2s" or "500ms".
- Input plugin Gathers will no longer be logged by default, but a Gather for
_each_ plugin will be logged in Debug mode.
- Debug mode will no longer print every point added to the accumulator. This
functionality can be duplicated using the `file` output plugin and printing
to "stdout".

## 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](https://github.com/influxdata/telegraf/blob/master/docs/CONFIGURATION.md)
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.

## v0.12.1 [2016-04-14]

### Release Notes
- Breaking change in the dovecot input plugin. See Features section below.
- Graphite output templates are now supported. See

## v0.10.3 [2016-02-18]

### Release Notes
- Users of the `exec` and `kafka_consumer` (and the new `nats_consumer`
and `mqtt_consumer` plugins) can now specify the incoming data
format that they would like to parse. Currently supports: "json", "influx", and
"graphite"
- Users of message broker and file output plugins can now choose what data format
they would like to output. Currently supports: "influx" and "graphite"
- More info on parsing _incoming_ data formats can be found
[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md)
- More info on serializing _outgoing_ data formats can be found
[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md)
- Telegraf now has an option `flush_buffer_when_full` that will flush the
metric buffer whenever it fills up for each output, rather than dropping
points and only flushing on a set time interval. This will default to `true`

fields.
- Graphite output now inserts tags into the bucket in alphabetical order.
- Normalized TLS/SSL support for output plugins: MQTT, AMQP, Kafka

## 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](https://github.com/influxdata/telegraf/blob/master/plugins/inputs/docker/README.md)
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`)

## 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](https://github.com/influxdata/telegraf/pull/379): Riemann output, thanks @allenj!

- [#354](https://github.com/influxdata/telegraf/pull/354): Add ability to specify multiple metrics in one statsd line. Thanks @MerlinDMC!

### Bugfixes
- [#371](https://github.com/influxdata/telegraf/issues/371): Kafka consumer plugin not functioning.
- [#389](https://github.com/influxdata/telegraf/issues/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](https://github.com/influxdata/telegraf/pull/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.

- [#360](https://github.com/influxdata/telegraf/pull/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

## 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
