From the featured tab of the app store – Mendix Application Performance Diagnostics
Hi Suraj,
It depends on the metrics you would like to collect. I hope you had a look at Metrics page that comes with Mendix cloud option.
Also take a look at https://docs.mendix.com/howto/monitoring-troubleshooting/manage-app-performance
I have also used datadog, which is can be used free for limited reports.
