You can view the Presto statistics on the graphical Presto Web UI.

Prerequisites

Presto has been installed in a cluster.

Accessing the Presto Web UI

  1. Go to the cluster details page and choose Components.

    • If the Components tab is not displayed on the cluster details page, complete IAM user synchronization first. (On the Dashboard tab page of the cluster details page, click on the right side of IAM User Sync to synchronize IAM users.)
    • For MRS 1.8.10 or earlier, log in to MRS Manager. For details, see Accessing MRS Manager. Then, choose Services.

  2. Select Presto. In the Presto Summary area, click Coordinator (Active) in Presto Web UI. The Presto web UI is displayed.

    When accessing the Presto web UI for the first time, you must add the address to the trusted site list.
