ATD keeps the analysis reports in HTML, PDF, and other formats as files in the back-end. When you get a request for an analysis report, the user interface copies the analysis report of the requested format from the back-end file system.
The GUI then presents it if the analysis report file exists.
If the analysis report file no longer exists in the back-end file system, the user interface shows a report with
Severity: -2, and
Description: Report not available - Analysis incomplete.
The ATD system uses a built-in scheduled disk cleanup task. The task deletes old analysis report files from the back-end to free up disk space.
The clean-up triggers when the disk usage reaches its internal threshold. The task deletes the analysis files from the oldest, until the disk usage lowers to the internal threshold.
The lifetime of analysis report files depends on how much scan load your ATD can take.
The model of your ATD that determines the available disk space, vATD, has the least disk capacity. This low capacity means that you might see this issue when viewing any recent scan results.
In a busy ATD installation, the lifetime of an analysis report can be as short as three days.
To verify if your analysis report file is deleted owing to the disk cleanup task, perform the steps below:
- Collect the Support Bundle from your ATD appliance.
- Note or screenshot the analysis report in question.
- Open a Service Request quoting this article number.
- Attach the data to your Service Request.
