Multiple maxscale nodes connecting to multiple mariadb 10.5.x nodes
Description
We have the following application and database topology. On each maxscale node we deploy https://github.com/Vetal1977/maxctrl_exporter to scrape the rest api and turn its output into prometheus stats every 30 seconds. Under periods of high connection load to our maxscale instances, we find that the maxctrl_exporter is unable to scrape the rest api in a timely fashion. Attached is a screenshot showing dropped/missing stats for an example period.
Would it be possible to add an admin thread that can be used to scrape the rest api and be guaranteed to return more timely?
