# Telegraf Controller reference documentation

#### Telegraf Controller is in Public Beta

Telegraf Controller is in public beta and will be part of the future Telegraf Enterprise offering. While in beta, Telegraf Controller is **not meant for production use**. The Telegraf Controller documentation is a work in progress, and we are actively working to improve it. If you have any questions or suggestions, please [submit an issue](https://github.com/influxdata/docs-v2/issues/new?labels=Telegraf%20Controller). We welcome any and all contributions.

Beta expectations

-   **No configuration or agent limits**  
    While in beta, Telegraf Controller doesn't place any limits on the number of configurations you can store or the number of Telegraf agents you can track. However, upon being generally available, the free distribution of Telegraf Controller will have limits introduced, with the option to increase limits through a Telegraf Enterprise license.
-   **Potential breaking changes**  
    While in beta, we will do our best to no longer make breaking changes to Telegraf Controller, however, they may be necessary. The majority of changes we make will be additive and non-breaking, and include any necessary migrations. When we do need to make breaking changes, we will do our best to communicate them clearly and in advance to minimize disruption.
-   **Flexible release schedule**  
    While in beta, we will continue to create new releases of Telegraf Controller, but likely at irregular intervals. We will provide [Telegraf Controller release notes](/telegraf/controller/reference/release-notes/) to make it easy to track updates.
