Accessing the Presto Web UI
You can view the Presto statistics on the graphical Presto web UI. You are advised to use Google Chrome to access the Presto web UI because it cannot be accessed using Internet Explorer.
Prerequisites
- Presto has been installed in a cluster.
- The cluster client has been installed, for example, in the /opt/client directory. The client directory in the following operations is only an example. Change it based on the actual installation directory onsite.
Accessing the Presto Web UI
- Access the component management page.
- For versions earlier than MRS 3.x, click the cluster name to go to the cluster details page and choose Components.
If the Components tab is not displayed on the cluster page, synchronize IAM users. (In the Dashboard area of the cluster details page, click Click to synchronize on the right of IAM User Sync to synchronize IAM users.)
- For MRS 3.x or later, log in to FusionInsight Manager. For details, see Accessing FusionInsight Manager (MRS 3.x or Later). Choose Cluster > Name of the desired cluster > Services.
- For versions earlier than MRS 3.x, click the cluster name to go to the cluster details page and choose Components.
- Select Presto. In the Presto Summary area, click Coordinator (Active) next to 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.
