DNS 2008 Recursive Timeout Per Second

Microsoft.Windows.DNSServer.2008.Monitor.RecursiveTimeoutPerSecond (UnitMonitor)

Knowledge Base article:

Summary

This monitor measures the average threshold of the Performance Counter : DNS/ Recursive TimeOut /sec. If the threshold is exceeded over five samples, then the monitor is unhealthy.

Configuration

Enabled:

This determined if the monitor is enabled or not.

Generate Alert:

This determines if the monitor will generate an alert.

AutoResolve Alert:

This determines if the monitor will auto-resolve (become healthy) if the triggering condition no longer exists.

Alert Priority:

Set the Alert Priority. Default is ‘Medium’.

Alert On State:

This determines which state causes the monitor to generate an alert. Default is ‘The monitor is critical’.

Alert Severity:

This determines the Alert Severity. The default is ‘Match Monitor Health’.

Threshold:

The numeric value that triggers the monitor. Default : 500

Frequency:

This determines how often the monitor will run. Default : 900 seconds.

Resolutions

Verify connectivity to the DNS server by pinging or performing a manual nslookup
