Overview: iHealth

You can use BIG-IP iHealth to verify that the hardware and software for your managed devices is operating properly and at peak efficiency. iHealth is a tool that collects data about elements of device configuration, logs, command output, password security, license compliance, and so on. You can use the iHealth diagnostics to identify any issues that require your attention.

When you create a task to gather iHealth diagnostics, Enterprise Manager captures a snapshot of the specified device in the form of a qkview file. The iHealth service compares the device's information to an F5 database containing known issues, common configuration errors, and F5 published best practices. Enterprise Manager then displays the results of this evaluation, which includes:

  • Descriptions of configuration issues or code defects
  • Recommended solutions
  • Associated link(s) to the AskF5 Knowledge Base for reference

In many cases, you can use this customized diagnostic information to resolve common configuration issues without contacting F5 Technical Support for help. If you do require assistance from F5 Technical Support, this iHealth data can help F5 engineers provide you with a resolution more quickly.

Specifying credentials to access iHealth diagnostics service

To send iHealth data for diagnosis, you must have an AskF5 Knowledge Base user name and password, which you can obtain at https://login.f5.com/resource/registerEmail.jsp.
