The Applications page
Applications (left nav) is your catalog of instrumented services. Each row is a service emitting traces, with its health at a glance and metadata you control.
What each row shows
- Service Name — the service's identity (e.g.
checkout-api). - Error Rate, latency and throughput for the selected time range.
- Owner Team and Tags — organize and route ownership.
Cookbook: organize your services
- Open Applications; use the search box to find a service.
- Click a service to open its detail view.
- Set the Owner Team and add Tags (e.g.
tier:1,domain:payments) so you can filter and so alerts route to the right team. - Adjust the time range (top right) to compare today vs last week.
If a service is missing
It hasn't sent traces yet. Instrument it (see Instrumenting your services): attach the agent / OpenTelemetry SDK with your ingest key, then send traffic — it appears within ~1 minute.
