The best way to ensure your NGINX Plus servers are healthy and stable is to set up a robust NGINX Plus monitor which can provide thorough monitoring and swift alerting services. Applications Manager's NGINX Plus monitoring tool collects important metric data and interprets it in visual and tabular formats for easy understanding. Its monitoring capability is not limited only to web servers and websites; it can monitor your entire IT infrastructure. To know more, refer NGINX monitoring.
To monitor a Nginx Plus instance follow the steps given below:
Go to the Monitors Category View by clicking the Monitors tab. Click on Nginx Plus under the Web Server/Services Table. Click on the desired Nginx Plus monitor to view the attribute data.
