warn or indicate when a service is no longer working / responding

Using the Service Manager in WebHost Manager you can toggle monitoring for applicable services; if a service is detected as having failed you may automatically receive a notification of the event. Please see the following documentation (with reference menu navigation paths for WHM):

• WHM: Main >> Server Configuration >> Basic cPanel/WHM Setup >> Contact Information
• WHM: Main >> Server Configuration >> Tweak Settings >> System
  • ChkServd TCP check failure threshold [?] The number of times a ChkServd TCP check must fail before notification is sent and the service is restarted. On heavily loaded systems these types of service checks fail occasionally, producing erroneous indications that services are down. A value of 3 or higher is recommended for most systems.
• WHM: Main >> Server Contacts >> Change System Mail Preferences
• WHM: Main >> Server Contacts >> Contact Manager
• WHM: Main >> Service Configuration >> Service Manager
• WHM: Main >> Server Status >> Service Status
• cPanel: Main >> Stats menu: Server Status

If the aforementioned features are not what you are looking for, please elaborate into further detail of the desired enhancement and how it may differ.

 

Please let me know the ticket ID number of your support request; I would like to review the specific circumstances involved.

Based on the information provided thus far I can only offer speculation as to what may be the cause. I would venture to guess that e-mails were generated and attempted to be sent but the messages were held in the mail server queue because they could not be successfully delivered to the intended recipient.

I recommend checking the mail server logs to determine exactly why each specific message could not be delivered; you should find detail that indicates the cause and then be able to take appropriate corrective action.

 

Search the Exim logs to identify why e-mails may have been delayed or failed delivery

Thank you for the information. I confirm that the noted resolution was to thaw messages that were frozen in the Exim mail server queue and then force a new attempt to deliver all messages in the mail queue.

The issue may be prevented by first identifying the root cause and then applying any necessary corrective measures, where applicable. To help obtain information about potential causes, including any possible errors, I recommend searching the Exim mail server logs for the message ID of an e-mail that was delayed. The message ID can most easily be obtained while viewing the full e-mail headers (source) of a received message. The Exim log information should help to identify a specific cause or at least narrow the possibilities to investigate further. The following post details how to search the Exim logs for a specific message ID: cPanel Forums - View Single Post - how to tell Exim to resend emails due to greylisting on other server?

 

Friendly Moderator Note

To better organize the evolved, unique topic of discussion I have relocated this thread into the forums category for cPanel and WHM Discussions. To help clarify the feature request status, it is important to note that the requested functionality is currently available using existing features in cPanel and WebHost Manager (WHM) as detailed in an earlier reply posted to this thread.
