leak

• 1. Spawn a bunch of servers:
  • another-fast: a node with a linear memory leak
  • fast: a node with a linear memory leak
  • slow: a node with a memory leak that grows very slowly
  • plain: a node with no memory leak
• 2. Spawn an artillery for each node that loads it with a small but constant stream of requests
• 3. Spawn Prometheus that watches the cpu/memory of each node

Then, locally we start the same server and we can see the different instances and an aggregate of the metrics for each job.

usage

λ docker-compose up
λ node .

Go to http://127.0.0.1:8000/ and see the result. The Prometheus is also listening at http://127.0.0.1:9090/
