Hi, with patches [1,2] merged recently into master branch, oVirt UI (WebAdmin and UserPortal) now persists client-side log records in browser's local storage [3] in addition to logging them via console.log API [4]. This means that client-side logs are kept in browser's storage between browser restarts, unless the user manually clears the storage. To inspect "localStorage" object in Firefox: * Menu / Developer / Toggle Tools * on Console tab, type "inspect(localStorage)" Client-side logs now use application-specific key prefix, e.g. "ENGINE_WebAdmin_MyKey" or "ENGINE_UserPortal_MyKey" to avoid clashes. For backwards compatibility (any existing items with un-prefixed keys), UI has a fallback to read the un-prefixed key when the prefixed one is missing. (Newly persisted items always use the key prefix.) In addition to changes above, any uncaught errors that originate from UI code are now properly caught and logged. This means that you shouldn't see uncaught JavaScript errors in browser's error console anymore.
