Trend reports are not displaying data
Web Security Help | Web Security Solutions | Version 7.8.x
When you use presentation reports, you can generate trend reports to provide trend information by day, week, month or year. There are separate tables in the Log Database that maintain trend data for each of these time periods.
If the trend reports you generate contain no data, first see:
*
All reports are empty
*
Error generating presentation report, or report does not display
*
Trend data is missing from the Log Database
If these topics don't help to determine the problem, verify that:
*
The report you are running is defined for a trend period that has valid data.
There are 4 different time periods for which trend data can be stored, for which reports can be defined: daily, weekly, monthly, or yearly. Make sure there is trend data for the time option selected for the trend report you are running.
*
Presentation reports is connected to the Log Database.
If the connection to the Log Database has been lost, the presentation reports tool cannot create the reports. See Log Database is not available.
*
There is disk space available for the report to be created and stored.
The presentation reports tool writes to the disk when it generates a report. See Inadequate disk space to generate presentation reports.
