System Documentation
What problem does it solve?
This Skill helps on-call engineers diagnose and understand load imbalances within CockroachDB clusters, explaining why the Multi-Metric Allocator (MMA) did or did not take specific rebalancing actions.
Core Features & Use Cases
- Cluster Balance Assessment: Analyzes resource distribution (CPU, disk, network) across cluster nodes and stores.
- Rebalancing Timeline: Reconstructs the sequence of rebalancing events, identifying triggers and actions.
- MMA Performance Analysis: Evaluates MMA's success/failure rates and identifies reasons for inaction.
- Use Case: An engineer notices high CPU on a few nodes. They use this Skill to understand if MMA is aware of the imbalance, if it attempted rebalancing, and why it might have failed or been ineffective, providing clear evidence from metrics and logs.
Quick Start
Investigate MMA behavior on the 'prod-us1' cluster for the last 4 hours.
