With Prometheus how to monitor a scaled Docker service where each instance serves its own /metrics?
I have a Prometheus setup that monitors metrics exposed by my own services. This works fine for a single instance, but once I start scaling them, Prometheus gets completely confused and starts tracking incorrect values.
All services are running on a single node, through docker-compose.
This is the job in the scrape_configs:
- job_name: 'wowanalyzer'
static_configs:
- targets: ['prod:8000']
Each instance of prod tracks metrics in its memory and serves it at /metrics. I'm guessing Prometheus picks a random container each time it scraps which leads to the huge increase in counts recorded, building up over time. Instead I'd like Prometheus to read /metrics on all instances simultaneously, regardless of the amount of instances active at that time.
