Hi,

What follows is just my humble opinion.  I think you’re putting the light on the fact that there are two distinct (but intricate at some level)  domains when speaking about “monitoring”. And both could be achieved more or less proactively.

 - the one you’re talking about, which is about performance, measurement
 - the other one, which Centreon (which was originally a tool to ease the configuration of the Nagios Status Engine, which was the original software that created the paradigm that Centreon (and some others) are still using today, is it oriented toward alerting and availability 

This is hard to know exactly what you mean by “support” in your title, but Centreon being plugin based, you can easily imagine having a plugin which relies on, for example, Selenium, which collects the performance metric of some scenarios for WebUI. I don’t think Centreon is aimed at performance analysis, as a  (proprietary) tool like Dynatrace can be.

Centreon is, IMO, a more versatile tool, whom the job is to monitors “status”, those status being possibly the level of performance of a given UI scenario, but also the temperature of a server room, the usage of a disk, the price of a commodity, etc… anything.

I’d conclude saying you’re talking about just a particular aspect of what Centreon is expected to monitor, but in another hand, for this particular aspect, there are some more specialized tools better aimed at for this domain of monitoring, and that would typically be exploited by Centreon and its pluging architecture  .
