Did anyone actually solve the labor tracking thing? I tried logging my hours for a quarter and gave up after three weeks. Reinstalling the iDRAC firmware at 2am because it bricked during an update doesn't feel like billable time when it's your own box.
Real and basically impossible to compare. My "maintenance" is mostly running Ansible playbooks I wrote two years ago while watching TV. Is that labor? The spreadsheet says zero but my weekend says otherwise.
Also 52 days late but @MeritBudi — did you factor drive replacement into your TCO? R740 backplane loves eating SAS cables around year three in my experience.
