Prometheus runs as a standalone service.  It doesn't run under Apache.

Prometheus is written in Go, and distributed as pre-compiled binaries (or as Go source code).  It doesn't depend on anything in the Java ecosystem.

Prometheus doesn't have "plugins" as such.  Rather, you run separate "exporters" which collect data. Prometheus fetches data from the exporters by making HTTP(S) requests to them, a process known as "scraping".

To upgrade, you just stop it, replace the binary, and restart it.
