Prometheus Grafana

Question

I can connect the prometheus server running as a docker image on Grafana to display monitoring of some components like cpu usage, memory etc but how to connect a system running on port 8080 to be scraped by prometheus on Grafana

Answer 1

You have 2 options:

• running the prometheus/grafana stack using 'host' network mode so they can access your service running on localhost port 8080
• have a 'monitoring' external network where all containers could reach each other

I prefer the latter.
