TiUP can only scale out or scale in the components of the TiDB cluster itself, such as TiDB, PD, and TiFlash. It cannot scale out third-party components like Grafana, Alertmanager, and Prometheus, right?

It is possible to scale in and out Grafana, Alertmanager, and Prometheus components normally. I have tested it. The method is the same as scaling in and out TiDB nodes.

Similarly, you can use tiup to scale out monitoring to multiple nodes. If you want to make monitoring alerts highly available, you can deploy multiple sets of Prometheus, Alertmanager, and Grafana. However, tiup will point Grafana to the first Prometheus instance, so you need to add other data sources for all Grafana instances.
