ZFS Observability – Extracting vdev metrics for storage insight

OpenZFS provides a wealth of both real-time and historic metrics to monitor, but it requires experience to understand those metrics and what they mean for your workload.

Join our hosts as they drill down into the metrics to determine the health of a pool, explain performance bottlenecks, and even break usage down per dataset.

What will you learn?

  • How to access the different kinds of metrics
  • How to feed the metrics into your monitoring system
  • How to make sense of the results
  • What to alert on, and what is normal
  • How to decide when you need to change your pool

Improving Recovery Objectives with OpenZFS

This talk discusses two key concepts in mission continuity: the Recovery Point Objective (RPO) and Recovery Time Objective (RTO). RPO can be understood as “how long has it been since your last good backup,” while the equally important but less-frequently discussed RTO can be understood as “how long until recovery is completed.”
