Performing Cluster Maintenance

Manages planned cluster maintenance across all deployment tiers. For Self-Hosted, this means draining and restarting individual nodes. For Advanced/BYOC, this means configuring and managing maintenance windows for CRL-applied patches. For Standard and Basic, maintenance is fully managed with no customer action required.

When to Use This Skill

• Planning OS patching, hardware changes, or configuration updates (Self-Hosted)
• Configuring or modifying a maintenance window (Advanced, BYOC)
• Setting patch deferral policies (Advanced, BYOC)
• Monitoring during a CRL-managed maintenance event (Advanced, BYOC)
• Running pre-maintenance validation checks (Self-Hosted, Advanced, BYOC)
• Understanding how maintenance affects your application (all tiers)
• Preparing applications for maintenance events (all tiers)

For permanent node removal: Use managing-cluster-capacity. For pre-maintenance health check: Use reviewing-cluster-health. For version upgrades: Use upgrading-cluster-version.
