v1.3.0 [2017-05-09]

Release Notes

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 [2017-02-01]


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


  • Go (golang) version update 1.7.4 -> 1.7.5

v1.2 [2017-01-24]

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.

  • Use RFC3339 timestamps in log output.
  • Non-default HTTP timeouts for RabbitMQ plugin.

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
  ## Address and port to host Webhook listener on
  service_address = ":1618"

should now look like:

# A Webhooks Event collector
  ## Address and port to host Webhook listener on
  service_address = ":1618"

    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.
