Telegraf is a plugin-driven server agent for collecting & reporting metrics. Telegraf has plugins to source a variety of metrics directly from the system it’s running on, pull metrics from third party APIs, or even listen for metrics via a statsd and Kafka consumer services. It also has output plugins to send metrics to a variety of other datastores, services, and message queues, including InfluxDB, Graphite, OpenTSDB, Datadog, Librato, Kafka, MQTT, NSQ, and many others.
Here are some of the features that Telegraf currently supports and make it a great choice for metrics collection.
- Written entirely in Go. It compiles into a single binary with no external dependencies.
- Minimal memory footprint.
- Plugin system allows new inputs and outputs to be easily added.
- A wide number of plugins for many popular services already exist for well known services and APIs.
