Set up dependencies
Dependencies are checks that define the availability of servers (e.g.,
ISA Server or Proxy Server) and services (e.g., DNS Server or DNS
Client) required by a target computer (i.e., on which a target computer
is dependent). The specified dependency check(s) must be
successfully executed before the other monitoring checks can be run.
E.g., If you access the Internet through a Proxy Server, an ICMP Ping
dependency check can be set to check the availability of the Proxy
Server, before executing HTTP/HTTPS monitoring checks. If the
dependency check fails, the HTTP/HTTPS check will not be run but
will be classified as a ‘Failure by Dependee’. For further information on
check status classification, please refer to the ‘Check State Indicators’
section in the ‘Monitoring check status’ chapter.
TIP: Use dependencies to avoid receiving a flood of alerts, when
servers on which other computers depend are down.

successful before this check is allowed to execute.
