TiKV-related monitoring
- Resource-related
  - Cluster - Store Size/Available Size: Pay attention to whether the disk space usage of each store is balanced and whether the free space is sufficient

  - Cluster - CPU/Memory/IO Util: Pay attention to whether the machine resource usage of each store, such as CPU, memory, and IO Util is balanced and how much it is used, set appropriate alarm thresholds to avoid degradation of availability due to full resources

  - Cluster - MBPS/QPS: Pay attention to whether the reads and writes traffic and QPS of each store are balanced. If there is an obvious imbalance indicating that there is a read/write hot spot, you need to further troubleshoot which tables and indexes have reads and writes hotspots in conjunction with the Dashboard heatmap

  - Cluster - Region/Leader: Pay attention to whether the number of Region and Leaders on each Store is balanced, whether there are more than 50,000 or more Region in a single Store, too many Region will cause excessive heartbeat pressure, it is best to scale out or merge in time Region to reduce Region number of regions, or temporarily turn on silent regions to reduce heartbeat overhead
