  7. Monitoring

    By clicking on the "Performance Monitoring" button, a new tab with a monitoring tool will be opened. This tool measures and calculates statistics on an application's actual operation depending on the usage of the application by users. It is mainly based on statistics of requests and evolution charts.
    One of the most important statistics you can measure under "Performance Monitoring" is the number of active HTTP sessions during a predefined period. You can preview the statistics report containing the number of concurrent users.

    Preview report with the number of connected users

      There are two ways to view the statistics report containing the number of concurrent users:
    1. Click the "HTTP sessions" to preview connected users' reports during the time you choose (During the day in this case).
    2. On the same page, under the System information, click the link "View HTTP sessions."

    Preview a report – Click the HTTP sessions

    You can see on the picture the statistics of monitoring taken on the exact date and the exact time divided by categories. After choosing the "HTTP sessions-1 day" option, you can see the report that shows the number of HTTP sessions per day. The report shows the duration of the session by each user. The number of users signed in the application within the time shows on the chart. The monitoring tool tracks the number of users signed in the session measured by a time. Take a look at the chart report below, and there you can preview the number of HTTP sessions during a day.

    Note: One HTTP session is equivalent to the one signed-in user.
      There are the following actions available with the HTTP sessions report:
    1. Return back – returns you to the monitoring home page.
    2. Return to the monitoring page (monitoring home page).
    3. Update the chart (report).
    4. Display reports in PDF format.
    5. Display online help on a new page– opens the help of a monitoring tool.
    6. Download the monitoring tool on your computer.

    1. Day – preview daily statistics report.
    2. Week – preview weekly statistics report.
    3. Month – preview monthly statistics report.
    4. Year – preview yearly statistics report.
