Maintenance

Learn how to maintain Polkadot SDK-based networks, focusing on runtime monitoring, upgrades, and storage migrations for optimal performance. Proper maintenance ensures your blockchain remains secure, efficient, and adaptable to changing needs. These sections will guide you through monitoring your network, using runtime versioning, and performing forkless upgrades to keep your blockchain secure and up-to-date without downtime.

In This Section

Runtime Upgrades

This page covers how runtime versioning and storage migration support forkless upgrades for Polkadot SDK-based networks and how they factor into chain upgrades.

Storage Migrations

Ensure smooth runtime upgrades with storage migrations, update data formats, and prevent errors. Learn when and how to implement migrations efficiently.

Runtime Metrics and Monitoring

Learn how to monitor and visualize node performance in Polkadot SDK-based networks using telemetry, Prometheus, and Grafana for efficient runtime monitoring.
