Measures reported by Exc2013SubDriTest

When a user attempts to send an email to a mailbox on the same Mailbox server or another Mailbox server, the Mailbox Transport Submission service on the source Mailbox server uses the Store Driver to connect to the mailbox database using RPC and retrieves the e-mail to be delivered. Many agents run within the store driver to facilitate email pickup and delivery. If any of these agents fail, it can result in the failure of or unprecedented delays in email delivery. If this is to be averted, administrators should track the status of each of the agents running within the store driver, promptly capture agent failures, and revive the agent before its failure impacts email delivery. For this, administrators can use the Exc2013SubDriTest test.

This test monitors every agent running within the submission store driver and reports the percentage of failures encountered by the agent during the last 5 minutes. Besides alerting administrators to agent failures, this test also pinpoints error-prone agents.

The measures made by this test are as follows:
