Troubleshooting options

If you have trouble getting the rSeries system set up and configured, there are some options available to help you.

You can also search the knowledge articles on my.f5.com.

You can also use these commands to help with troubleshooting. You can type a question mark (?) or press the Tab key to see possible command completions in the CLI.

Generate system reports (QKView) from the webUI

You can generate a QKView file from the webUI. The report contains diagnostic information, such as configuration data, log files, and platform information.

1. Log in to the webUI using an account with admin access.

2. On the left, click DIAGNOSTICS > System Reports.

   The System Reports screen displays. A list of QKView files that were previously generated are shown with any reports that were uploaded to iHealth.

3. To generate a system report, click Generate QKView in the upper right corner of the screen.

   The Generate QKView box displays these additional options:

   Option	Description
   Filename	Specify a name for the file to which QKView file data is written. The default filename is <system-name>.tar.
   Timeout Value	Specify the time in seconds after which to stop QKView file data collection. The default value is 0, which indicates no timeout.
   Max File Size	Exclude all files greater than the specified size (in MB). The range is from 2 MB to 1000 MB. The default value is 500 MB.
   Max Core Size	Exclude core files greater than this size (in MB). The range is from 2 MB to 1000 MB. The default value for maximum core size is 25 MB.
   Exclude Cores	Specify whether core files should be excluded from the QKView file. The default is to include core files.

Note: The system runs many commands to collect the diagnostic information, so generating the report might affect its performance.

It takes a few minutes for the system to finish creating the report and list it on the screen. The QKView Status changes to `File generated successfully` when it is done.

4. To upload the report to the F5 iHealth server,

   a. select the check box next to the QKView name.

   b. Click Upload to iHealth.

   c. In the Upload to iHealth popup, enter your iHealth credentials.

   Optionally, you can include your F5 Support case number and a brief description.

To do the upload, the system must have DNS configured, and have Internet access to these services using the HTTPS/443 remote service/port:

-   api.f5.com
-   ihealth-api.f5.com

The QKView tar file uploads to iHealth, where you can get help to diagnose the health and proper operation of the system.

5. To delete a QKView file, select it and click Delete.

Generate a tcpdump

You can use the tcpdump utility to capture traffic on your system. You can then save the captured traffic as a file that can be analyzed to help troubleshoot network issues.

Note: Generating a tcpdump is only supported on the F5 r5000/r10000/r12000 platforms.

1. Connect using SSH to the management IP address.

2. Generate a tcpdump.

   system diagnostics tcpdump

   These options are available to use with this command:

Note: The system supports the use of standard tcpdump options. For more information, see www.tcpdump.org/manpages/tcpdump.1.html.
