What is iHealth?

The F5® iHealth® server is a tool that helps you troubleshoot potential issues. It does this by analyzing configuration, logs, command output, password security, license compliance, and so on.

From F5 BIG-IQ® Centralized Management, you can create a snapshot of a configuration in the form of a QKView file and then upload it to the F5 iHealth server. The file is compared to the iHealth database, which contains known issues, common configuration errors, and F5 published best practices. F5 returns an iHealth report you can use to identify any potential issues that you need to attend to.
