Troubleshooting using iHealth
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.
How do I get access to send QKView files for my managed devices to
the F5 iHealth diagnostics server?
You'll need a single sign on (SSO) to the F5
Support site to access the F5 iHealth diagnostics server. If you don't have one yet,
register at https://login.f5.com/resource/login.jsp
With access to the F5 iHealth diagnostics server you can upload QKView files and download
iHealth reports for your managed devices.

Upload a QKView file to the F5 iHealth server to troubleshoot
potential issues
To upload a QKView file, you must have access to
the F5 iHealth server configured on BIG-IQ Centralized Management.
You upload a QKView file to F5 Networks to create an iHealth diagnostics report. You can
use that report to troubleshoot potential issues with a managed device.
- On the left, click.
- Click theQKView Uploadbutton.
- In theNamefield, type a name to identify this report, and type an optional identifier in theDescriptionfield.
- If you have (and want to associate) a support case number with this QKView file, type that into theF5 Support Case Numberfield.This step is not required.
- From theCredentiallist, select the credentials to log in to the iHealth diagnostic site.
- From theAvailablelist, click the device you want to upload a QKView file for.
- Click theSave & Closebutton.
When BIG-IQ finishes uploading the QKView file(s)
to F5, it displays a status icon next to it on the Tasks screen.
If the upload fails, click the report's
Name
link and view the error
message for more information. After F5 successfully receives the QKView file it creates an
iHealth report. To view this report, go to the Device Reports screen.Troubleshoot potential issues by viewing an iHealth device
report
After you upload a QKView file for one or more
BIG-IP devices, the F5 iHealth server returns a device report.
Review the device report so you can address any potential issues or vulnerabilities. You
can also find out BIG-IP versions in which associated issues have been fixed and any
related solutions on AskF5.
- On the left, click.
- Click theOpenlink next to the report you want to view.

Create a schedule to upload QKView files to the iHealth
server
After you specify the credentials for a user to
access the F5 iHealth diagnostic server, you can create a QKView upload schedule.
Configuring BIG-IQ Centralized Management to upload QKView files to the F5 iHealth
diagnostic server on a regular basis means you'll get iHealth device diagnostics reports
sent automatically to BIG-IQ for your BIG-IP devices. This information makes it easy for
you to troubleshoot potential issues, and keeps you up-to-date about vulnerabilities that
could cause security issues for your devices.
- On the left, click.
- In theNamefield, type a name to identify this report, and type an optional identifier in theDescriptionfield.
- From theCredentiallist, select the credentials to log in to the iHealth diagnostic site.
- From theUpload Frequencylist, select how frequently you want to upload QKView files to the F5 iHealth server, and then select the day of the week or month.

- Select an end date for this schedule, or select theNo End Datecheck box.
- From theAvailablelist, select the device(s) you want to add to this schedule.
- Click theSave & Closebutton.
Now BIG-IQ will upload QKView files for the
selected device on the schedule you specified.
