To view charts, use Grafana.

The main metrics of the system are displayed on the dashboard:

  • CPU Usage: The total CPU utilization on all nodes (1 000 000 = 1 CPU).
  • Memory Usage: RAM utilization by nodes.
  • Disk Space Usage: Disk space utilization by nodes.
  • SelfPing: The highest actual delivery time of deferred messages in the actor system over the measurement interval. Measured for messages with a 10 ms delivery delay. If this value grows, it might indicate microbursts of workload, high CPU utilization, or displacement of the YDB process from CPU cores by other processes.
