Doubts on Grafana Enterprise - Integration with Oracle DB/Apache

Good Morning.
i am new on Grafana and in our company, the idea is to monitor the dbs + os + apache and other apps.
My doubt is that when i search for documentation, all is related to the integration with Grafana Cloud and in my case i will only use Enterprise because my client does not want to open ports and send his metrics over internet.
Then my point is if i can monitor or not with enterprise version, cause i can’t find plugins or docs without find in the title “with grafana cloud” lol…
