Workload Manager Metrics ​

This page documents Prometheus metrics related to the Workload Manager (WLM), which governs resource allocation and query concurrency across pools in Yellowbrick.

Purpose ​

The Workload Manager ensures fair and efficient use of system resources across multiple query workloads. This metric allows operators to:

  • Track how many queries are currently running or waiting in each resource pool
  • Identify pool-level contention or saturation
  • Detect imbalances between configured concurrency limits and actual usage
  • Optimize pool configurations based on query patterns

This metric is especially useful for SREs and platform admins monitoring SLA compliance or debugging queue buildup.
