Greetings @Naresh9999, currently, we don’t have immediate plans to improve MariaDB monitoring. However, we recommend utilizing an external service monitoring for maxscale as a temporary solution.
If you or anyone else is interested in setting it up and sharing your experience on Percona Community Blog - learn about MySQL, MariaDB, … | Percona Community, please don’t hesitate to let me know, and I will be happy to guide you through the setup process. Regrettably, I am not a maxscale user, so setting it up alone may take some time.
