Hi @dani9,
Monitoring Console is an App contained in Splunk Enterprise installation.
I can confirm that it's a very useful App when you need to monitor your distributed installation because gives to you a centered information point containing all the information about the health status of your infrastructure and permits to debug problems related to it (e.g. insuffiecnt CPUs).
I solved using MC a great performace problem caused by scheduled very heavy searches and I was able to understand the problem only watching panels in MC that displayed that there were peacks of CPU at fixed intervals and using MC I found the scheduled search that gave problems.
If you don't want it you can choose to not use it without consequences, but thinck carefully to this choice!
But you must know that Monitoring Console is an App that, when used, consumes resources, for this reason must be used on a dedicated server or at least not in a production Search Head.
Anyway it isn't an App that you use every day, but it's very useful to have always ready to debug problems and to check your infrastructuce because in one step you have a full check of your infrastructure and information if there's something wrong (e.g. THP, ulimits, indexing, space, etc...).
I hint to configure it and dedicate some time to see its dashboards, especially if you have a large infrastructure, in every part becuse you could need it!

Ciao.
