How to Decide
Telegraf is a free, open‑source agent that DevOps and IT teams use to collect, process, aggregate, and write metrics, logs, and other arbitrary data. The alternatives split into a few clear camps: Gatus is chosen for its built‑in health‑check status page and Prometheus‑compatible metrics export; Prometheus stands out with its multi‑dimensional time‑series database and powerful PromQL query language; SigNoz differentiates itself by delivering a unified observability stack that natively supports OpenTelemetry‑based logs, metrics, and distributed tracing; Loki is selected for its label‑only indexing that dramatically cuts storage costs while offering tight Grafana and Prometheus integration.
