AD Op Master Roles monitor. This monitor measures the general responsiveness of each operations master. The monitor periodically reports the Lightweight Directory Access Protocol (LDAP) bind and Internet Control Message Protocol (ICMP) ping time from each domain controller that is an operations master.

Associated rules generate alerts if a certain number of consecutive errors occur during these tests for a given operations master. This monitor tests the primary domain controller (PDC) emulator operations master every time it runs. The other operations masters are tested less frequently (as adjusted by a script parameter), unless an error occurred the last time a test was performed. In this case, the test is performed every interval until it completes successfully.
