Health Bar

The Health Bar provides a snapshot of the overall health of the devices configured at the site. If there are any potential issues, it is indicated by the status icon and corresponding descriptions are displayed. When there are multiple criteria issues, only the issue criteria with the highest priority is displayed. The <+x> next to the description indicates that there are more issues. You can hover over the value to view the description of the issue in a pop-up window. For more information, see Health Bar.

The descriptions displayed for the Potential Issue are corresponding to the issue encountered at the site. The following is a list of possible messages:

Offline gateway

To launch the Health Bar, complete the following steps:

In the WebUI, set the filter to a site.
Under Manage, click Overview > Site Health.
Click the status icon next to the site name, the Health Bar pop-up appears.
Click the pin icon to pin the Health Bar to the Site Health page.
