Health checks that test the service, not just the process
Proposed interface concept Not released. A design for discussion, drawn in HTML and CSS; not a screenshot of working software.
Resource history for hosts, application-level checks such as an IMAP sign-in test and mail queue length, container resource use, the dependencies each service relies on, and an outage timeline. The figures shown are example data.

Shape this before it is built
This screen is a proposal. MSP design partners review concepts like this one against how they actually run customers, and say what is missing.
