Paul Hauner 2b2a358522 Detailed validator monitoring (#2151) ... ## Issue Addressed - Resolves #2064 ## Proposed Changes Adds a `ValidatorMonitor` struct which provides additional logging and Grafana metrics for specific validators. Use `lighthouse bn --validator-monitor` to automatically enable monitoring for any validator that hits the [subnet subscription](https://ethereum.github.io/eth2.0-APIs/#/Validator/prepareBeaconCommitteeSubnet) HTTP API endpoint. Also, use `lighthouse bn --validator-monitor-pubkeys` to supply a list of validators which will always be monitored. See the new docs included in this PR for more info. ## TODO - [x] Track validator balance, `slashed` status, etc. - [x] ~~Register slashings in current epoch, not offense epoch~~ - [ ] Publish Grafana dashboard, update TODO link in docs - [x] ~~#2130 is merged into this branch, resolve that~~		2021-01-20 19:19:38 +00:00
