    Understanding the ISA Server Reporting Feature

    ISA Server includes a reporting feature that you can use for a number of purposes:

    • Use reports to obtain and view information on usage statistics of the server for both computers and client users.

    • Create your own reports.

    Each report here consists of a number of sub-reports, taking the form of charts and graphs. This concept is illustrated on the 2nd page of the Article:

    The predefined ISA Server reports are listed here:

    • Summary reports: These reports combine data from the Firewall service log and Web proxy service log, to show network traffic usage. Summary reports are sorted by application and are especially useful when you need to manage Internet connectivity, or determine trends traffic patterns.

    • Web Usage reports: These reports show information on how the Web is being used, and detail information on:

      • Top Web users

      • Common responses

      • Browsers in use

    Web Usage reports use information in the Web Proxy service logs.

    • Application usage reports: These reports show Internet application usage, and contains information on:Analyzing ISA Server Performance using ISA Server Reporting

      • Amount of incoming traffic

      • Amount of outgoing traffic

      • Top users

      • Client applications

      • Destinations

    You should use application usage reports to determine usage of published servers on the internal network, and to determine network saturation situations.

    • Traffic and utilization reports: These reports combine data from the Web Proxy logs and Firewall service logs to provide information on:

      • Internet usage by application

      • Internet usage by protocol.

      • Internet usage by direction.

      • Average peaks

      • Peak simultaneous connections

      • Cache hit ratio

      • Errors

      • Statistics

    Traffic and utilization reports can assist you with determining trends in usage, planning network capacity, monitoring network capacity, and determining bandwidth policies.

    • Security reports: These reports combine data from the Web Proxy service logs, Firewall service logs and Packet Filter logs. You can use the information in security reports to:

      • Monitor for attempts to breach network security.

      • Monitor for security violations.

      • Monitor for network attacks.

    To view reports:

    1. Open ISA Management.

    2. Expand the Monitoring Configuration node.

    ISA Server reporting works by combining all summary logs from each ISA Server computer in the array in a single report database on each ISA server. The report database is stored in the location that you indicate when you create the specific report job. Report databases are by default stored in the ISAReports folder of the ISA installation folder.

    The ISA Server reporting feature allows you to schedule reports to be generated at specific times:

    • Daily

    • Weekly

    • Monthly

    • Yearly

    • After data has been collected for a predefined time period.

    To configure report jobs, you specify the following:

    • Time period that data must be collected from the ISA log files.

    • Schedule when the report will be generated – this is based on the time period for which data must be collected from the log files.

    For each report job, the user name and password that you configure must have sufficient privileges to generate the reports on the ISA server. The user name and password credentials provided must have the following permissions:

    • Must be a member of the Domain Admins group. Members of this group have rights to generate reports on the ISA server.

    • Must have local administrator rights on each ISA Server computer in the array.

    • Must have rights to access DCOM objects on each ISA Server computer in the array.
