SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps users diagnose and resolve slow Bazel builds, high build costs, and infrastructure bottlenecks by analyzing build performance data.

Core Features & Use Cases

  • Diagnose Slow Builds: Pinpoint critical path bottlenecks, regressions, and parallelism gaps.
  • Optimize Remote Execution: Reduce queue wait times, right-size worker fleets, and cut RBE costs.
  • Debug Cache Misses: Identify reasons for cache misses and recommend targeted fixes.
  • Use Case: A user asks, "Why did my Bazel build take 20 minutes today?" This Skill analyzes the build's performance metrics to identify the root cause, such as a cache miss on a critical compilation step or high queue wait times on Buildbarn workers, and provides actionable recommendations.

Quick Start

Use the hermetiq skill to analyze my latest build for performance bottlenecks.

FAQPage Schema
How do I diagnose slow Bazel builds and identify critical path bottlenecks?

To diagnose slow Bazel builds, you analyze action execution telemetry to pinpoint critical path bottlenecks, parallelism gaps, and regressions using detailed performance data.

What causes Bazel remote execution cache misses and how can I fix them?

Bazel remote execution cache misses are diagnosed by analyzing cache hit and miss telemetry to identify root causes, enabling targeted fixes to improve cache effectiveness.

How do I optimize Buildbarn worker fleets to reduce remote execution queue wait times?

You optimize Buildbarn worker fleets by analyzing infrastructure health and queue wait times to right-size workers, reducing remote execution bottlenecks and cutting costs.

Can I use Bazel build telemetry to reduce high remote execution infrastructure costs?

Yes, analyzing Bazel build telemetry reduces remote execution costs by identifying queue wait times and parallelism gaps, allowing you to right-size worker fleets efficiently.

What is the best way to find out why a Bazel build suddenly takes much longer to complete?

The best way to investigate sudden Bazel build slowdowns is analyzing performance metrics to identify root causes like cache misses on critical steps or high queue wait times.
