Hot off the presses from the AskF5 team, I bring to you the announcement many of us have been waiting for...iHealth for the masses! If you don't know what iHealth is yet, get out from under your rock and check it out. It's an amazing analysis, investigation and error prevention tool that's free for those with a support contract. It really is as cool as it sounds, and offers tons of helpful, impossible to find elsewhere features. Do yourself a favor and try it out.  And now, the announcement, which contains the iHealth news as well as plenty of other AskF5 related goodies :

F5 is excited to announce that BIG-IP iHealth is now available to everyone

BIG-IP iHealth is an F5-hosted tool that enables you to verify the proper operation of your BIG-IP
system and ensure your hardware and software function at peak efficiency.

The technology at the heart of BIG-IP iHealth is the qkview file, which provides a running snapshot of
your BIG-IP system with up-to-the-minute configuration and diagnostic information. You can quickly
download a qkview file from your BIG-IP system, and then upload the file to the BIG-IP iHealth system.

The BIG-IP iHealth system translates the output from your qkview file and displays the content in a
customer-friendly format that mimics the familiar BIG-IP Configuration utility. In addition to
translating the raw data, the BIG-IP iHealth Diagnostics component of the BIG-IP iHealth system
evaluates the logs, command output, and configuration of your BIG-IP system against a database
of known issues, common mistakes, and published F5 best practices. The prioritized results provide
tailored feedback about configuration issues or code defects, and provide a description of the issue,
recommendations for resolution, and a link to further information in the AskF5™ Knowledge Base.

This customized diagnostic information enables you to take the recommended action, and in many
cases, can help you resolve common configuration issues without the need to contact F5 Technical
Support. If you require assistance from F5 Technical Support, your BIG-IP iHealth data will be
available to F5 engineers for faster resolution.

Avoiding the 497 day jiffies counter bug in the Linux 2.4 kernel

To avoid any issues which may result from the 497 day jiffies counter bug in the Linux 2.4 kernel,
customers should schedule an annual reboot of their BIG-IP LTM, GTM, ASM, WebAccelerator,
Link Controller, WAN Optimization and FirePass systems. Although the counter bug is not an F5
software defect, and all issues known to affect F5 products have been patched in current product
versions, an annual reboot is recommended to avoid any other issues which may arise.

For more information (including which product versions are affected), refer to SOL7036 The Linux
uptime counter wraps after 497 days. This issue was addressed by a kernel upgrade in BIG-IP
version 10.1.0; therefore, this issue does not affect BIG-IP versions 10.1.0 and later.
