RAS Performance Monitor requirements/troubleshooting tips

APPLIES TO:
  • Parallels Remote Application Server 16.2

Requirements for installing RAS Performance Monitor

  • RAS Performance Monitor can be installed on 64bit OS only.
  • Make sure that the port TCP 3000 is opened and not occupied by any 3rdparty app.To view performance metrics, the Parallels RAS administrator uses the dashboard (Grafana, port TCP 3000), which displays the visual representation of performance counters in real time.

  • We do recommend to install RAS Performance Monitor on dedicated server.
  • On the servers which will be monitored it is required to open port TCP 8086. RAS Telegraf service collecting a predefined set of performance counters at a fixed time interval (10 seconds). It then sends the collected data to the InfluxDB database (to the machine where RAS Performance Monitor installed) for storage using port TCP 8086
