Service-Map Stateful Processor

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

Note: service_map_stateful processor has been renamed to service_map. You can use either name for now but the support for service_map_stateful will be removed in major version 3.0.

Usages

Example .yaml configuration:

processor:
    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 AbstractProcessor, service-map-stateful processor introduces the following custom metrics.

Gauge

  • spansDbSize: measures total spans byte sizes in MapDB across the current and previous window durations. This only tracks the byte size for the file (if used).
  • traceGroupDbSize: measures total trace group byte sizes in MapDB across the current and previous trace group window durations. This only tracks the byte size for the file (if used).
  • spansDbCount: measures the total spans across the current and previous window durations.
  • traceGroupDbCount: measures the total trace groups across the current and previous trace group window durations.
  • relationshipCount: measures the total relationships stored

Developer Guide

This plugin is compatible with Java 8. See
