Investigating potential LoadMaster performance issues


Like all software appliances, factors such as excessive traffic volumes or software errors can result in performance issues or unexpected reboot(s). With High Availability in place this can be ensured to have minimal impact on application service.

In any case it is important to investigate and diagnose any such issues. With the right investigating and diagnoses these can easily be identified and prevented.

Below are some checks that can be performed if there appears to be any performance issues or unexpected restarts of the LoadMaster device.
