This page aims to ease the transition from Telegraf 1.1 to Telegraf 1.2. It is not intended to be a comprehensive list of the differences between the versions. See Telegraf’s Changelog for detailed release notes.
The StatsD plugin also no longer save its 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.
