## AI overview

Telegraf Controller 1.1 introduces fleet-wide configuration management through global constants, configuration groups, aliases, and versioning. The release also adds high availability with automatic failover for Telegraf Enterprise deployments.

## Source excerpt

Telegraf is easy to stand up. You just need a config file with a few plugins and data flows. That ease is why Telegraf fleets grow fast, and why managing the agents that collect data becomes more difficult than collecting it. A change that takes minutes on ten agents takes days across a few hundred. Telegraf Controller is a centralized control plane for managing, configuring, and monitoring your fleet of Telegraf agents. Telegraf Controller 1.1 is available today and addresses that management problem from two sides: keeping the Controller layer itself reliable, and making fleet-wide changes without touching every config. The release adds high availability, configuration versioning, global constants, configuration groups, and aliases. High availability (Telegraf Enterprise) High availability lets you run multiple Controller instances from a shared database with automatic failover. If an instance goes down, agents keep pulling configuration and reporting health through the remaining instances. For production monitoring, compliance systems, and other mission-critical pipelines, the configuration layer needs to meet the same reliability requirements as the rest of the stack. High availability also simplifies planned maintenance: one instance can go offline for patching and the config path stays open. In strict environments that require redundancy, it also removes Controller as a single point of failure. Configuration versioning Configuration versioning saves every configuration change as a new version, including who made it. If an edit causes errors, compare the current version against the previous one in a side-by-side, color-coded diff and revert. Configuration history also provides an audit trail. Teams can trace when individual settings changed and test tuning changes without losing the last working configuration. Global constants Global constants let you define a value once (an output endpoint, a collection interval, a region name) and reference it from any configu
