Observability
A conceptual telemetry pipeline: applications emit metrics, logs, and traces; OpenTelemetry collects them; Prometheus, Loki, and a trace store hold the signals; Grafana is where they are queried. It is not a diagram of any employer's system.
Conceptual flow: Applications (Applications), flowing into Signals (Metrics, Logs, Traces), flowing into Collection (OpenTelemetry), flowing into Telemetry backends (Prometheus, Loki, Trace store), flowing into Metric storage (Thanos / Mimir), flowing into Dashboards (Grafana)
