System monitor

The System Manager provides the capability to monitor Core performance over a period of time. Core collects the performance information into log files. MobileIron Technical Support uses these files to diagnose Core performance issues.

The files contain information about:

  • CPU usage
  • memory usage
  • threads
  • tomcat performance
  • database performance
  • mysql logs

You can download the files, or upload them to an external server that MobileIron Technical Support specifies.

To monitor Core performance when working with MobileIron Technical Support, go to the System Manager to Troubleshooting > System Monitor.

You can run the system monitor daily and on demand. If you are experience Core performance issues, collecting system monitor logs can help MobileIron Technical Support diagnose the issue.

  1. Log into System Manager.
  2. Go to Settings > Log Upload.

  3. To upload system monitor logs to an HTTPS server, enter the URL of the HTTPS server.

    Typically, you enter https://support.mobileiron.com/uploads/ when working with MobileIron Technical Support.
