Tetra Hub v2 Monitoring and Alarms

For Tetra Hub v2, the following infrastructure-level notifications are sent to TetraScience by AWS automatically:

• Disk Space Alarm: Indicates when a Hub is using more than 90% of its available disk space.
• Heartbeat Metric: Validates the connection (heartbeat) between the TDP and a Hub every minute. If the TDP doesn’t receive a heartbeat message for more than 20 minutes or if the metric stops reporting, the platform assumes that the Hub is offline.
  • Offline Alarm: Indicates when a Hub is offline by using the Heartbeat Metric.
• Proxy Heartbeat Metric: Validates the connection (heartbeat) between the TDP and each Hub’s proxies every minute. If the TDP doesn’t receive a proxy heartbeat message for more than 20 minutes or if the metric stops reporting, the platform assumes that the Hub’s proxy is offline.
  • Proxy Offline Alarm: Indicates when a Hub’s proxy is offline by using the Proxy Heartbeat Metric.
