Operating Cortex

This section covers day-2 operation of a Cortex cluster. Start here if you are running Cortex in production.

Core operator guides

• Monitoring Cortex — install the bundled dashboards, alert rules, and recording rules.
• Troubleshooting — symptom-driven decision tree for the write path, read path, storage, and rings.
• Upgrading — version-to-version upgrade procedure, component ordering, and downgrade caveats.

Specialized topics

• Scaling the Query Frontend
• Query Auditor — detect query correctness regressions.
• Query Tee — compare two Cortex deployments side-by-side.
• Requests Mirroring with Envoy

For component-level operational guidance (HA pairs, shuffle sharding, zone replication, capacity planning, encryption), see the Guides section.
