You can monitor traffic, memory usage, CPU usage, task queue, and other metrics on the Pulse tab in Flussonic UI.

  • Memory usage for the last hour/minute. Total memory usage on the server.
  • CPU usage for the last hour/minute. Total CPU usage on the server.
  • Scheduler utilization for the last hour/minute. The graph of the Erlang scheduler usage.
  • Erlang active tasks for the last hour/minute. The number of active Flussonic tasks on the server.
  • Disk space usage for each disk on your server.
