I can't display "All Interfaces Availability Report" in Report section. When I try the message that I receive is "No data available" but this is not true. In fact if I go into the router interface section I can see the interface availability for today, yesterday, etc. I created an "custom monitor" (I called it "Interface_status") with .1.3.6.1.2.1.2.2.1.7 mib and it functions well when I perform a test. If I go in the report section and I choose both router and "Interface_status" I can't display the report. What can I do to fix it?
