Investigate use of prometheus #24

Open dylanmcreynolds opened 4 years ago

dylanmcreynolds commented 4 years ago

It's important to have some sort of instrumentation framework available for services. One popular framework is prometheus. Let's try it out.

See this: https://rollout.io/blog/monitoring-your-synchronous-python-web-applications-using-prometheus/

This issue describes a trial of prometheus. We will plug the code into Flask as outlined in that blog post. Then, in splash-deploy, we will fire up a prometheus service in the docker-compose such that it talks the /metrics endpoint and collects information. Success this task will be a system that captures response times and information and can be viewed with the prometheus web app. We hope to gain knowledge about how useful prometheus might be in deployments.

Update to this issue, I think I don't want prometheus in the splash-deploy. While it's still probably easiest to run prometheus from docker, I don't want to muddy splash-deploy with it. For this initial test, fire up prometheus however you want, but don't put it in splash-deploy docker-compse*.yml
