## Issue Addressed Closes #2528 ## Proposed Changes - Add `BlockTimesCache` to provide block timing information to `BeaconChain`. This allows additional metrics to be calculated for blocks that are set as head too late. - Thread the `seen_timestamp` of blocks received from RPC responses (except blocks from syncing) through to the sync manager, similar to what is done for blocks from gossip. ## Additional Info This provides the following additional metrics: - `BEACON_BLOCK_OBSERVED_SLOT_START_DELAY_TIME` - The delay between the start of the slot and when the block was first observed. - `BEACON_BLOCK_IMPORTED_OBSERVED_DELAY_TIME` - The delay between when the block was first observed and when the block was imported. - `BEACON_BLOCK_HEAD_IMPORTED_DELAY_TIME` - The delay between when the block was imported and when the block was set as head. The metric `BEACON_BLOCK_IMPORTED_SLOT_START_DELAY_TIME` was removed. A log is produced when a block is set as head too late, e.g.: ``` Aug 27 03:46:39.006 DEBG Delayed head block set_as_head_delay: Some(21.731066ms), imported_delay: Some(119.929934ms), observed_delay: Some(3.864596988s), block_delay: 4.006257988s, slot: 1931331, proposer_index: 24294, block_root: 0x937602c89d3143afa89088a44bdf4b4d0d760dad082abacb229495c048648a9e, service: beacon ```
