17.4 Ganglia Statistical Graphics Are Not Displayed in the Web Browser
The OES Remote Manager frame sends secure content. However, Ganglia uses scripts to graphically display statistics that send the statistical data via HTTP instead of HTTPS. Depending on how your web browser is configured to handle mixed content on a web page, the Ganglia statistics might not be displayed in the graph windows.
17.4.1 Firefox
In Firefox 23 and later, when you access a page with both HTTPS and HTTP content, a shield icon 
appears in the address bar, and the browser automatically blocks certain content such as non-secure scripts. To allow mixed content, right-click the shield icon, then select . After you disable protection, an orange alert icon 
appears in the address bar and makes you aware that the displayed page contains mixed content.
In a Mozilla Firefox 22 and earlier web browser, you receive a warning, but content is not automatically blocked. A pop-up dialog box reports: You have requested an encrypted page that contains some unencrypted information. Click to dismiss the warning and allow mixed content to be displayed.

icon replaces the lock to the left of the https:// in the address bar. Right-click the icon to view the message that advises: Your connection to this site is only partially encrypted, and does not prevent eavesdropping.
17.4.2 Internet Explorer
In a Microsoft Internet Explorer web browser, the pop-up dialog box is displayed at the bottom of the page and reports: Only secure content is displayed. Click to dismiss the warning and allow mixed content to be displayed.
17.4.3 Chrome

While mixed content is displayed in Chrome, the green text https:// and lock in the URL 
, which indicates secure-only content, is automatically changed to red text that is crossed out and a gray lock with a red X
