Sharepoint 2019 enterprise managed metadata service is inaccessible - false alarm

Daniel 61 Reputation points


We got alot of these errors, event id 8088, The Managed Metadata Service '' is inaccessible.

Our SCOM environment are looking for these event ids and send us notifications. Every time I log in and double check the metadata service IS available. Just minutes after the alarm.

Why is the event triggered? How should we monitor this without too many false alarms?

    Hi @Daniel ,

    This can occur if the server is offline or the managed metadata service is not started or has been disabled. The service might not start if the application pool account does not have sufficient permissions to the term store.

    Resolution:   Verify the application pool account permissions

    1. Verify that the user account that is performing this procedure is a member of the Farm Administrators group.
    2. On the Central Administration Home page, click Application Management.
    3. On the Application Management page, in the Service Applications section, click Manage service applications.
    4. On the Service Applications page, in the Type column, click the managed metadata service application, and then click Properties.
    5. In the Create New Managed Metadata Service dialog box, in the Application Pool section, record the name of the application pool and the application pool account name.
    6. Click Cancel.
    7. Log on as a member of the local Administrators group.
    8. In Central Administration, on the Service Applications page, in the Type column, click the managed metadata service application, and then click Permissions.
    9. Confirm that the account that you recorded in step 5 has one of the following permissions:
      • Read Access to Term Store
      • Read and Restricted Write Access to Term Store
      • Full Access to Term Store
