v1.30.0

Deprecation removals

This release removes the following deprecated plugins:

inputs.cassandra
inputs.httpjson
inputs.io
inputs.jolokia
inputs.kafka_consumer_legacy
inputs.snmp_legacy
inputs.tcp_listener
inputs.udp_listener
outputs.riemann_legacy

Furthermore, the following deprecated plugin options are removed:

mountpoints of inputs.disk
metric_buffer of inputs.mqtt_consumer
metric_buffer of inputs.nats_consumer
url of outputs.influxdb

Replacements do exist, so please migrate your configuration in case you are still using one of these plugins. The telegraf config migrate command can help with migrating to newer plugins.

Important Changes

The default read-timeout of inputs.syslog of five seconds is not a sensible default as the plugin will close the connection if the time between consecutive messages exceeds the timeout. Telegraf 1.30.0+ sets the timeout to infinite (i.e zero) as this is the expected behavior.
Telegraf 1.30.0+ correctly sanitize PostgreSQL addresses, which may change the server tag value for a URI-formatted address that contains spaces, backslashes or single-quotes in non-redacted parameters.

v1.27.0

Important Changes

Timezone Parsing: Fix parsing of timezone abbreviations such as MST. Up to now, when parsing times with abbreviated timezones (i.e. the format ) the timezone information is ignored completely and the timestamp is located in UTC. This is a golang issue (see #9617 or #56528). If you worked around that issue, please remove the workaround before using v1.27+. In case you experience issues with abbreviated timezones please file an issue!
Internal Parser methods: Removal of old-style parser creation. This should not directly affect users as it is an API change. All parsers in Telegraf are already ported to the new framework. If you experience any issues with not being able to create parsers let us know!

v1.26.0

Important Changes

Static builds: Linux builds are now statically built. Other operating systems were cross-built in the past and as a result, already static. Users should not notice any change in behavior. The _static specific Linux binary is no longer produced as a result.
telegraf.d behavior: The default behavior of reading /etc/telegraf/telegraf.conf now includes any .conf files under /etc/telegraf/telegraf.d/. This change will apply to the official Telegraf Docker image as well. This will simplify Docker usage when using multiple configuration files.
Default configuration: The telegraf config command and default config file provided by Telegraf now includes all plugins and produces the same output across all operating systems. Plugin comments specify what platforms are supported or not.
State persistence: State persistence is now available in select plugins. This will allow plugins to start collecting data, where they left off. A configuration with state persistence cannot change or it will not be able to recover.

v1.9.0

Release Notes

The HTTP Listener (http_listener) input plugin has been renamed to InfluxDB Listener (influxdb_listener) input plugin and use of the original name is deprecated. The new name better describes the intended use of the plugin as an InfluxDB relay. For general purpose transfer of metrics in any format using HTTP, InfluxData recommends using HTTP Listener v2 (http_listener_v2) input plugin.
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 overconsumption when reading from queue consumers, the following input plugins use the new option max_undelivered_messages to limit the number of outstanding unwritten metrics:
- Apache Kafka Consumer (kafka_consumer)
- AMQP Consumer (amqp_consumer)
- MQTT Consumer (mqtt_consumer)
- NATS Consumer (nats_consumer)
- NSQ Consumer (nsq_consumer)

Release notes

The MySQL (mysql) input plugin has been updated fix a number of type conversion 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, see Metric version in the MySQL input plugin documentation.

You are 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 (postgresql) input plugin 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 SQL Server (sqlserver) input plugin has a new query and data model that can be enabled by setting query_version = 2. Migrate to the new model, if possible, since the old version is deprecated and will be removed in a future version.
The OpenLDAP (openldap) input plugin has a new option, reverse_metric_names = true, that reverses metric names to improve grouping. Enable this option, when possible, as the old ordering is deprecated.
The new HTTP (http) input plugin, when configured with data_format = "json", can perform the same task as the, now deprecated, HTTP JSON (httpjson) input plugin.

v1.3.0

Changes to the Windows ping plugin

Users of the windows ping plugin will need to drop or migrate their measurements 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.

Changes to the Ceph plugin

For the Ceph plugin, 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

Rewritten Riemann plugin

The Riemann output plugin has been rewritten and the previous riemann plugin is incompatible with the new one. The reasons for this are outlined in issue #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.

New Socket Listener and Socket Writer plugins

Generic Socket Listener and 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.

v1.2.1

Bug fixes

Fix segfault on nil metrics with InfluxDB output.
Fix negative number handling.

Features

Go (golang) version update 1.7.4 -> 1.7.5

v1.2

Release Notes

The StatsD plugin will now default all “delete_” config options to “true”. This will change te default behavior for users who were not specifying these parameters 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. The reason for this is that saving the state in a global variable is not thread-safe (see #1975 & #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.

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

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

Features
