Java Integration
Collect Java metrics and distributed traces with Guance DataKit in minutes. One-click setup, 40+ key metrics, full documentation.
The Guance Java integration captures RED metrics and distributed traces via the standard ddtrace-compatible or OpenTelemetry agent — attach it with one JVM flag, no code changes. GC pauses, thread-pool saturation, and slow spans land in the same view, so latency investigations start from evidence, not guesses. Sampling strategy and alert thresholds are covered in the APM guide below.
| Spec | Detail |
|---|---|
| Collector | DataKit input ddtrace / otlp |
| Protocol | ddtrace-agent protocol or OTLP (traces) + JMX (metrics) |
| Key metrics | JVM heap/GC, thread pools, RED per service, trace waterfalls |
| Prerequisites | Attach the Guance-compatible Java agent or OTel Java agent |
| Dashboard | Pre-built Java dashboard, auto-installed on first data |
| Deep dive | APM Monitoring Guide |
Set up in minutes — install DataKit, enable the
ddtrace / otlpinput, and your first Java metrics appear in Guance within about a minute. Full field list and alert-rule templates live in the APM Monitoring Guide.
