MS Exchange DAG CopyQueue Length
This check monitors the number of transaction logs waiting to be copied
and inspected on your Exchange Mailbox Servers, i.e. the CopyQueue length.
The check requires that the agent plugin msexch_dag.ps1 is installed
on the Exchange mailbox server(s) to be monitored. The plugin uses the
PowerShell Get-MailboxDatabaseCopyStatus cmdlet.
Warning and critical levels for the queue length can be configured and
the state of the check is determined according to these levels.
