  • Previous behavior:
    • Only tracks bridge latency on non-errors and status code 200

    • Tracks bridge latency for all requests. A new label is added to distinguish status code groups 2xx, 3xx, 4xx, 5xx
  • If you experience alert issues related to spike in bridge latency following upgrade: Please review your alerts and update accordingly. Example query sum by(name) (rate(bridge_latency_seconds{job=~"$node", status_code_group!~"5xx|4xx"}[$__rate_interval]))
• Introduces new allowNoBootstrapper flag, when set to true, allow bootstrapper list in OCR2 job spec to be empty and enables single-node consensus for testing
