Telegraf version 0.2.4 now supports the MailChimp API, allowing users to gather metrics from email campaigns and forward them to InfluxDB or other configured output sinks. The new plugin requires an API key to be inserted into the configuration file, and can be set to collect only reports for campaigns sent within a certain number of days ago. Users can test the plugin by running `telegraf` with the configuration file, which will output the collected metrics in InfluxDB line protocol format. This is just one of several third-party APIs that Telegraf plans to support in the future, including AWS Metrics, and users are encouraged to contribute plugins for other services.
