Telegraf¶

About

Telegraf is a leading open source server agent to help you collect metrics from your stacks, sensors, and systems. More than 200 adapters to connect to other systems leaves nothing to be desired.

Telegraf is a server-based agent for collecting and sending all metrics and events from databases, systems, and IoT sensors. Telegraf is written in Go and compiles into a single binary with no external dependencies, and requires a very minimal memory footprint.

Overview

IoT sensors: Collect critical stateful data (pressure levels, temperature levels, etc.) with popular protocols like MQTT, ModBus, OPC-UA, and Kafka.
DevOps Tools and frameworks: Gather metrics from cloud platforms, containers, and orchestrators like GitHub, Kubernetes, CloudWatch, Prometheus, and more.
System telemetry: Metrics from system telemetry like iptables, Netstat, NGINX, and HAProxy help provide a full stack view of your apps.
