I'm currently working on a (very) sticky TM1 instance that I've inherited. Whilst I go through the usual archival / feeder tightening / useless logic removal / etc to try and improve performance, I'm once again looking at some easy to view way of informing the user base of the status of the TM1 server when it's locked up.
Main ways I've dealt with this in the past -
Given access to TM1Top
Found this often resulted in "What's Person x doing?" type responses. You know, those ones that are really popular in no-blame cultures.
Website linked in to TM1 / semaphore system
TI creates a file in prolog, removes in epilog and website draws a big arrow showing a free / TI running status whilst checking the TM1 instance is actually up every couple of mins. Went ok but doesn't do much for model locks and not realistic in the size of system I currently have.
Ignoring user base and getting random phonecalls
Sticking fingers in your ears and going "na na na na na" or putting a juniour developers phone number as a contact details is always an option!
I don't feel that gives many options and of the ones above, none of these are practically very useful in the current system so was just wondering if anyone had a better approach for this?
Open to suggestions

TIA
