Submission Store Driver Agents Test

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 Submission Store Driver Agents 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.

Target of the test : A Microsoft Exchange 2013/2016 server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each store driver submission agent

Configurable parameters for the test
  1. Test period - How often should the test be executed
  2. Host - The host for which the test is to be configured.
  3. port – The port at which the host listens.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Store driver submission agent failure:

Indicates the percentage of failures encountered by this agent in the last 5 minutes. 


A value close to 100% is a cause for concern as it indicates continuous failure of the submission agent.
