Croway opened a new pull request, #24689:
URL: https://github.com/apache/camel/pull/24689
## Summary
_Claude Code on behalf of Croway_
New `camel-test-infra-observability` module providing a local
Apache-2.0-only observability stack via `camel infra run observability`.
Composes 4 containers on a shared Docker network:
- **Prometheus** (`:9090`) — scrapes Camel metrics at `:9876/observe/metrics`
- **VictoriaTraces** (`:10428`) — receives OTLP traces
- **VictoriaLogs** (`:9428`) — receives OTLP logs
- **Perses** (`:3000`) — dashboard UI, auto-provisioned with Camel project
and overview dashboard
### Changes
- **New module**: `test-infra/camel-test-infra-observability/` with 4
container classes, service interface, multi-container orchestrator
- **New export target**: `--open-telemetry-agent-export=observability`
enables traces + logs export to the stack
- **Deprecated**: `--open-telemetry-agent-export=jaeger` in favor of `otlp`
(backward compatible)
- **Generalized**: `OpenTelemetryTracer.exportTarget` check accepts any
non-empty value instead of hardcoded `"jaeger"`
- **Fixed**: Fork version propagation in `Run.java` — forked JBang processes
now inherit the CLI's catalog version
- **OOB dashboard**: Perses auto-provisioned with Camel Overview dashboard
(exchanges, throughput, failure rate, processing time, JVM memory/threads/GC,
CPU, load average)
### Usage
```bash
# Start the observability stack
camel infra run observability
# Run a Camel app with full observability (metrics + traces + logs)
camel run MyRoute.java --observe \
--open-telemetry-agent --open-telemetry-agent-export=observability
```
### Verified
- Prometheus scrapes Camel metrics (zero-config with `--observe`)
- VictoriaTraces receives OTel agent spans (Kafka, JDBC, HTTP
auto-instrumented)
- VictoriaLogs receives logs with trace_id/span_id correlation
- Perses dashboard shows exchanges, throughput, processing time, JVM metrics
- Multiple Camel instances supported via `--management-port`
## Test plan
- [ ] `camel infra run observability` starts all 4 containers
- [ ] `camel infra get observability` returns JSON with all endpoint URLs
- [ ] `camel run --observe` sends metrics to Prometheus
- [ ] `camel run --observe --open-telemetry-agent
--open-telemetry-agent-export=observability` sends traces and logs
- [ ] Perses dashboard at `:3000/projects/camel/dashboards/overview` shows
data
- [ ] `camel infra stop observability` stops all containers
- [ ] `--open-telemetry-agent-export=jaeger` still works (backward
compatible)
- [ ] `--open-telemetry-agent-export=otlp` works as new generic external
export
