    Performance counters are collected to Log Analytics so you need to create alert with custom log search. I would suggest to explore first to check the KQL language first and check Perf table in Log Analytics. That is where LogicalDisk(_Total)% Disk Time metric data is. It is unclear what exactly you want to alert upon so you will need for figure out the language.
