Realtime Metrics

OS Metrics​

These metrics give immediate visibility into the operating system status:

  • CPU Usage – Current CPU consumption of the appliance.
  • Memory & Swap Usage – Amount of memory in use and swap space utilization. High swap usage can indicate memory pressure.
  • Root Filesystem Usage (/) – Used vs available disk space on the system root partition.
  • Datastore Usage – Current used capacity of the ZFS datastore.
  • Datastore Fragmentation – Fragmentation percentage, useful for anticipating performance degradation.

Job Executor Metrics​

Job executor metrics provide insights into the internal job scheduling and execution engine:

  • Core Pool Size – Maximum allowed concurrent jobs.
  • Largest Pool Size – Highest number of threads created so far.
  • Current Running Tasks – Number of tasks being executed.
  • Total Tasks in Queue – Pending tasks waiting for execution.
  • Executor Pool Usage (%) – Utilization of the job executor pool.
  • Average Execution Time per Task – Performance indicator of task duration.
