What's already running
The one-click deployment brings up SigNoz as a multi-container Docker Compose stack: ClickHouse for trace, log, and metric storage, an OpenTelemetry Collector for ingestion, a query service, PostgreSQL for the metastore (accounts, dashboards, alert rules), and the frontend UI — all started and networked together automatically. Expect roughly 1.5-2 GB of RAM in use at idle before any telemetry even arrives, since ClickHouse and its supporting services stay resident in memory.
First login
Open the SigNoz dashboard at the address shown in your Leneex panel and you'll land on a setup screen asking you to create the admin account yourself — there's no default username or password, so whoever fills in this form first becomes the organization's first admin.
Sending telemetry
SigNoz's one click automation gets the backend running, but it doesn't instrument your applications for you: point your services' OpenTelemetry SDK or Collector at your server's OTLP endpoint (gRPC or HTTP) to start receiving traces, metrics, and logs. Once the first spans arrive, service maps and RED-metric dashboards populate automatically without extra configuration on your part.
