The Grafana-PD page’s Storage capacity is being double-counted for multiple TiKVs on a single physical machine. Can this be optimized?

The expression in Grafana is simply sum(pd_cluster_status{type=“storage_capacity”}). If you want to modify it, you can get the number of TiKV instances and then divide the total capacity by the number of TiKV instances.

In practice, it’s not always the case that there is only one TiKV per physical machine, so redundant calculations are still necessary.

Grafana expressions can be customized, right?

You can modify it yourself.
