Reports are a resource that provide captured views or analyses of information that can be viewed in the ArcSight Console in PDF, Excel, Comma Separated Value (csv), or Rich Text Format (rtf). You can view the HTML format with your preferred default Web browser.
You can create reports on all events, cases, notifications, and assets that are in storage.
Reports gather data based on Queries and Trends (How Trends Work), and use report templates to determine display and file formats.
For an overview of reporting, including information on queries, trends, and templates, see Building Reports.
