This is a special prepper that consumes Opentelemetry traces, stores them in a MapDB data store and evaluate relationships at fixed window_duration.

Usages

prepper:
    service-map-stateful:

Configurations

  • window_duration(Optional) => An int represents the fixed time window in seconds to evaluate service-map relationships. Default is 180.

Metrics

Besides common metrics in AbstractPrepper, service-map-stateful prepper introduces the following custom metrics.

Gauge

  • spansDbSize: measures total spans byte sizes in MapDB across the current and previous window durations.
  • traceGroupDbSize: measures total trace group byte sizes in MapDB across the current and previous trace group window durations.
