Dashboard or API metrics for Sequencer

[sanchaymittal]

Problem A clear and concise description of what the problem is

Ideas to solve this A clear and concise description of what you think could solve this problem.

• Number of bids for transfer (received, processed, sent, failed)
• Number of bids by Router (received, failed, sent, successful)
• The entry and exit time of transfer at Sequencer
• transfers metrics for given origin and destination domains
• Volume
• number of transfers
• fees earned by each router
• transfer per sec

Tasks that will be completed after working on this issue:

• 1542

• 1333

• 1543

Acceptance Criteria

• [ ] X happens
• [ ] Y happens

Other Update per P2P

P2 sequencer metrics (how many requests it got, how many bids per request were recieved, is there any request that got no bids for a long time)

1. RPCs/Subgraphs/Watcher/Gelato/etc. Some of them I know you monitor at your side, I plan to do RPCs monitoring for those endpoints that are specified in router config (once I would finish with all main metrics and alerts, I would move on to RPCs)
2. we definitely need to be calculated and exported on router container side: number of RPC connections per RPC endpoint. Cause not all RPC endpoints give such stats as above and we cannot get this info from anywhere else. If you can expose this info (just number of requests made, optionally you can specify method - it would simplify debug, as a label e.g. connext_rpc_requests{domain="6450786", url="https://bsc-dataseed.binance.org"} 351 or connext_rpc_requests{domain="6450786", url="https://bsc-dataseed.binance.org", method="eth_call"} 269 ) - it would be great. Just increase this count on any request, don't need to store it - once container is restarted just start from 0. The only thing - it's better to cut off URI part not to expose credentials. It would have additional side effect - we would see when router failovers to other RPCs, not using the first one

Implementing a lightweight version of tracking last bid time from the sequencer, instead of detailed metrics.
