# Telemetry Sources

> Telemetry Sources is the earlier name for OpenLIT Connectors — atomic backends, signal bindings, and AI read paths

**Telemetry Sources** is the same product surface as **Connectors**. Prefer the connectors and signal-routing guides below — they match the OpenLIT dashboard language (connectors, actions, and per-signal routing).

## Quick summary

OpenLIT reads raw traces, logs, and metrics from the built-in ClickHouse store by default. You can attach external backends supported in open-source OpenLIT — **Tempo**, **Loki**, **Prometheus**, and **Jaeger** — and bind each signal independently per [environment](/latest/openlit/organisation/environments). Derived intelligence always stays in ClickHouse via [Database Config](/latest/openlit/organisation/database-config).

For auth tables, AI selectors, correlation limits, and reliability hardening, see the [Connectors](/latest/openlit/organisation/connectors) page — that document is the canonical reference.
