Symptom & Impact

Metrics disappear from dashboards, reducing visibility for autoscaling and SLO tracking.

Environment & Reproduction

Often follows collector upgrades, endpoint cert rotation, or scrape timeout changes.

Root Cause Analysis

Collector throttling, dropped scrape targets, and auth/TLS mismatches are common causes.

Quick Triage

Check collector health, backlog, and scrape error rates by node.

Step-by-Step Diagnosis

Trace ingestion path from node exporter to storage backend.

Solution — Primary Fix

Tune scrape intervals, increase collector resources, and repair TLS/auth configuration.

Solution — Alternative Approaches

Use temporary local buffering and replay to prevent data loss during incidents.

Verification & Acceptance Criteria

Continuous metric flow resumes with no >1% scrape loss for 24h.

Rollback Plan

Revert collector image and monitoring config to last stable revision.

Prevention & Hardening

Add canary collectors and alert on early ingestion lag indicators.

Related Errors & Cross-Refs

Correlates with node runtime instability and network policy misconfigurations.
