Have you looked under Reports tab > Server monitor > Availability Summary report? You would get the availability summary including MTTR, Availability trend, Outage duration, details of every outage etc, for a selected monitor and for the selected time period. Is this what you are asking for? or is there anything else that you would require? Below is an example report.
2. Can you shed some light on "Server monitor disable report"? Do you need a report of all suspended server monitors? I would assume you need them for auditing purpose. It would be great if you can elaborate it a little more.
