    • Asynchronous Message Bus (AMB) graphs, available to view on the ServiceNow Performance homepage, use asynchronous communication to monitor the transaction count and response times, which provide a performance analysis.

    If you have an admin role, you can review performance metrics. The AMB graphs are intended for use by Customer Service and Support to troubleshoot performance issues.

    To view AMB graphs on the ServiceNow Performance homepage:
    1. In the Graph Set list, select AMB.
    2. In the Monitorable Items list, select an instance.
    3. In the Timespan list, select a time period.

    For details on using the graph and display controls on the Customer Service and Support Performance homepage, see Platform performance metrics.

    The following graph displays the maximum, median, and minimum response times in milliseconds over a user-selected timespan. The second graph shows the number of AMB transactions over a user-selected timespan.
