< BackIndexNext >


The Quality Assurance DNS Monitor test the Primary and Secondary DNS server's ability to correctly respond to DNS clients. A prefabricated DNS request is alternately sent to both DNS servers until either a DNS server responds, or the maximum test length expires.

This Monitor performs a name lookup on both servers and examines the results against a list of expected responses. The list of expected IP addresses allows for verifying the response in one of two ways:

1. the response must have all of the IP addresses listed 2. the response must have at least one of the IP addresses listed (round-robin configuration)

If both DNS servers fail to respond within the maximum test time, or with the appropriate content, ipMonitor considers this test as a failure.

This Monitor:

  • Considers the specified resource unavailable after a specified number of seconds.
  • Persistently tests the resource at specified intervals.
  • Disallows testing during a maintenance period.
  • Waits for a specified number of failures to occur before starting alerts.
  • Switches testing intervals, from "responding correctly" to "not responding correctly". Configurable intervals allow you to test more or less aggressively in the event of failure.
  • Stops alerting after a specified number of alerts.
  • Has a placeholder for a WinNT Service Name or any other information required by a recovery script.
