Summary of Changes
Hello @ti-chi-bot, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request introduces new documentation to the TiUP common operations guide. The added content provides users with a step-by-step process for transitioning their TiDB cluster's monitoring solution from the default Prometheus to VictoriaMetrics, which is beneficial for large-scale deployments. The guide covers setup for new clusters, migration for existing ones, and post-migration cleanup.
Highlights
- New Documentation Section: Adds a comprehensive guide on how to switch the monitoring component from Prometheus to VictoriaMetrics within a TiDB cluster managed by TiUP.
- Migration Steps: Includes detailed instructions for migrating an existing TiDB cluster from using Prometheus for monitoring to using VictoriaMetrics, covering enabling remote write, switching Grafana data sources, and viewing historical data.
- New Deployment Configuration: Provides configuration examples for setting up VictoriaMetrics as the primary monitoring solution for a new TiDB cluster deployment using TiUP.
- Cleanup Procedures: Outlines steps for cleaning up old Prometheus metrics and services after successfully migrating to VictoriaMetrics.

Code Review
The pull request successfully adds a new section detailing how to switch from Prometheus to VictoriaMetrics for TiUP-managed clusters. The documentation is well-structured, covering new deployments, migration of existing setups, and cleanup procedures. The changes adhere well to the provided style guide.
My review focuses on minor wording adjustments to further enhance clarity, conciseness, and user guidance, ensuring the instructions are as straightforward and safe as possible. The use of ordered lists, code blocks, and heading hierarchy aligns with the style guide. The introduction of VictoriaMetrics as an alternative monitoring solution is a valuable addition to the documentation.
