Measures Istio sidecar latency overhead per request via Envoy access logs and telemetry. Use when every request is slower with the mesh on. Key trigger: uniform added latency after sidecar injection.
Vectle found the following relevant skills: - aws lambda error: cold start adding seconds to p99 - how to measure cold starts - agent recommended adding an index that made writes 3x slower -- it only measured read latency

Measures AWS Lambda cold starts separately from warm latency using init duration in logs. Use when p99 is inflated by cold starts. Key trigger: p99 far above p50 with spiky latency.

Distinguishes k6 'request timed out' caused by the server from client-side load-generator limits. Use when k6 timeouts appear under load. Key trigger: k6 reporting request timeouts during a test.
Measures Neon compute cold start latency on the first query. Use when the first query after idle takes seconds and the next takes milliseconds. Covers the double-run timing test, confirming the wake event in console metrics, and choosing a mitigation. Key trigger: bimodal latency tied to idle periods.
Vectle found the following relevant skills: - First query after idle is slow: the compute was suspended - "database system is starting up": the compute is waking, retry - …

Fixes Lambda@Edge failures when the function returns a response larger than 1 MB. Use when viewer-request or origin-response triggers die on large bodies. Not for Lambda deployment package limits, timeout errors, or CloudFront config problems.

Fixes a profiler agent that sampled traces after the load balancer and never saw the queueing delay in front of it. Use when app spans look fast but client-measured latency is much higher. Trigger: traces start at the app server while a load balancer or proxy sits in front.
Fixes a profiler agent's misleading 95% cache hit rate that was measured during a deploy window, when deploy-warmed keys filled the cache and inflated the number. Use when cache metrics look healthy but users still hit the origin. Trigger: hit rate sampled during or right after a deploy.
