Feature Request: Prometheus Metrics

[SeaMonkey82]

The ability to expose a Prometheus metrics endpoint would be a welcome addition, as it is a standard feature in all other Ethereum clients.

I haven't looked at what other clients populate within their metrics. What would be a useful starting point for identifying what metrics would be helpful?

I think we should really do this. This will be also pretty valuable for ourselves to analyze stuff.

Maybe we can start a bit small here?

Guess we can take whatever we feel we would like to have here, no imminent need to copy over behavior from other clients (but likely good as a source for inspiration). So:

• Blocks executed per second
• Tx pool size
• Number of peer connections
• Memory load
• …

There is likely a lot of useful stuff to display.

Maybe we just pick the easiest out (tx pool size?) to get things started 🙂
