OpManager allows you to monitor the critical metrics in your network and helps in maintaining the integrity of the VPN connection. There are approximately 1000 firewall templates with built-in performance metrics shipped with OpManager. Apart from those templates, listed below are a list of VPN specific performance monitors that can be associated with the device. You can also create custom monitors as per your requirements. You can find these performance monitors under Settings -> Monitoring -> Performance Monitors.
