Managed Availability Monitoring Log

Managed availability, also known as Active Monitoring or Local Active Monitoring, is the integration of built-in monitoring and recovery actions with the Exchange high availability platform. It's designed to detect and recover from problems as soon as they occur and are discovered by the system. Unlike previous external monitoring solutions and techniques for Exchange, managed availability doesn't try to identify or communicate the root cause of an issue. It's instead focused on recovery aspects that address three key areas of the user experience:

  • Availability   Can users access the service?
  • Latency   How is the experience for users?
  • Errors   Are users able to accomplish what they want?

Managed availability is an internal process that runs on every Exchange 2013/2016 server. It polls and analyzes hundreds of health metrics every second. If something is found to be wrong, most of the time it will be fixed automatically. But there will always be issues that managed availability won’t be able to fix on its own. In those cases, managed availability will escalate the issue to an administrator by means of event logging. Using the Managed Availability Monitoring Log test, administrators can scan the event logs for information, warning, or error messages logged by the Managed Availability process, and capture critical errors/warnings that Exchange cannot self-heal using the Managed Availability engine.

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 the Exchange server monitored

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.
  4. log type – By default, Microsoft-Exchange-ManagedAvailability/Monitoringwill be set as the log type.
  5. dd frequency- Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against dd frequency.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Alert value:

Indicates the type of event that was captured and logged by the managed availability process in the event log during the last measurement period.


The values that this measure can take and their corresponding numeric values are as follows:

Measure Value Numeric Value








By default, this measure reports one of the Measure Values listed in the table above. In the graph of this measure however, the alert status is indicated by the corresponding numeric equivalents only.

Total alerts:

Indicates the total number of errors that the Managed Availability process logged in the event logs.


A high value is a cause for concern.
