Other Areas to Check for Performance Issues
1. Review the VisualRF log file:
 Check for validation errors
 Check for timing errors
2. Review the ssl_error_log and error_log:
 Check for out of memory errors
 Check for Apache web server errors
3. Review VisualRF > Floor Plans. It provides a complete status of how long each floor plan is taking to
generate and when it is generated next (you can tell if AMP is keeping up).
4. Review the System >Performance page; AMP could be out-of-memory, or AMP/Apache could be so bogged
they can't service VRF.
5. Send customer support the VisualRF Diagnostic Tar file as follows:
 Navigate to VisualRF >Floor Plans.
 Click on the Create VisualRF Diagnostic Tar File link.
 Save the tar file locally.
 Email tar file to support.dell.com.
