teor 6f8f4d8987 Provide recent syncer response lengths as a watch channel (#2602) ... * Minimal recent sync lengths implementation Also includes metrics and logging, to make diagnosing bugs easier. * Add logging to check what happens when Zebra reaches the chain tip * Add tests for recent sync lengths - initially empty - pruned to correct length - newest entries go first * Drop a redundant `/` from a Cargo.lock URL This seems to be a nightly or beta Rust change, but hopefully stable just accepts it. * Use metrics histograms to avoid overwriting values * Add detailed syncer monitoring dashboard * Increase the recent sync length to 4 This length makes it easier to distinguish between temporary and sustained errors/syncs.
