Chapter 1: What is BIG-IP iHealth?

BIG-IP® iHealth

™ enables you to verify the proper operation of your BIG-IP and

Enterprise Manager systems and ensures your hardware and software function at peak

efficiency.

BIG-IP iHealth is a free, F5®-hosted tool that is available at https://ihealth.f5.com. This

tool is available to customers running BIG-IP 10.x and later or Enterprise Manager 2.x

and later.

The technology at the heart of BIG-IP iHealth is the qkview file, which provides a

running snapshot of your BIG-IP or Enterprise Manager system with up-to-the-minute

configuration and logging information.

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 or Enterprise Manager system against a database of known issues, common

mistakes, security alerts, and published F5 best practices. The 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.

How are qkview files uploaded to the BIG-IP iHealth system?

In order to use BIG-IP iHealth, a qkview file needs to be created and uploaded to the

BIG-IP system. This happens either manually or automatically.

Manually

You can download a qkview file from your BIG-IP or Enterprise Manager system, and

then upload the file to the BIG-IP iHealth system.

Note: For detailed instructions about creating a qkview file, refer to SOL12878:

Generating BIG-IP diagnostic data using the qkview utility (10.x - 11.x).

Automatically

BIG-IP iHealth was integrated with the Enterprise Manager system starting with version

3.0.0. You can configure the Enterprise Manager system to automatically create and

upload qkview files (from BIG-IP and Enterprise Manager devices) to BIG-IP iHealth,

and then view the diagnostics of all of your managed devices on a single screen. For

more information about Enterprise Manager, refer to the product overview.

What does the BIG-IP iHealth system do with my qkview file?

The BIG-IP iHealth system has two main components: BIG-IP iHealth Viewer and BIG-

IP iHealth Diagnostics.

BIG-IP iHealth Viewer

The BIG-IP iHealth Viewer essentially translates the raw information pulled from your

qkview file and presents your system data in an easy-to-read format for fast access.

The BIG-IP iHealth Viewer displays clear summaries of your unit’s health and

configuration. Graphs showing performance metrics, such as CPU usage, throughput,

memory, and RAM cache, can be customized to show specific dates and times, so you

can focus on the appropriate information. By using an interface that logically organizes

data in the same way as your BIG-IP device interface, you can isolate the information

you want. You can also search within your configuration files, log files, BIG-IP iHealth

Diagnostics output, commands, and the graphical network map.

BIG-IP iHealth Diagnostics

The BIG-IP iHealth Diagnostics component takes advantage of technical knowledge of

experienced F5 engineers to assist you in implementing the best practices for your

system. Using advanced heuristics, the tool can determine when your system is operating

outside of normal levels so you can take steps to improve performance. BIG-IP iHealth

Diagnostics will also check for security issues and recommend patches or software

updates. Content is added regularly to give you fast access to emerging threats and newly

found issues.

F5 recommends uploading a qkview file to the BIG-IP iHealth system at least once a

month, since F5 updates the BIG-IP iHealth known issues and best practices database on

a weekly basis.

Chapter 2: How do I create a qkview file?

To get started using BIG-IP iHealth, you must generate a qkview file on your BIG-IP or

Enterprise Manager system.

1. Log in to BIG-IP or Enterprise Manager Configuration utility.

2. Click System.

3. Click Support.

4. Ensure that QKView is selected.

5. Click Start.

After a few moments, possibly several minutes on a busy system, the Download

Snapshot File button will appear, indicating that your qkview file is ready to

download.

6. To download the qkview file to your local computer, click Download Snapshot

File.

7. The default name for a qkview file is as follows:

case_number_____support_file.tar.gz

F5 recommends changing the name to include your case number and a count

identifier.

For example:

c123456_A_support_file.tar.gz

c123456_B_support_file.tar.gz

Note: You can also manually generate a qkview file using the command line qkview

utility. For information about the qkview utility, including detailed instructions about

creating a qkview file, refer to SOL12878: Generating BIG-IP diagnostic data using the

qkview utility (10.x - 11.x).

Chapter 3: How do I upload my qkview file into BIG-IP iHealth?

1. Navigate to https://ihealth.f5.com.

2. When prompted for a login account, use your F5 WebSupport credentials.

3. To upload a new qkview file, click Upload.

4. Click Choose File.

5. Browse to the location of the qkview file on your computer.

6. Optional: If you have an open support case with F5 Technical Support, you may add

your case number to the F5 Case field. If you do not have an open support case

related to this qkview file, leave the field blank.

7. Optional: You may add your own identifier to the External Case field for tracking

purposes.

8. Click Upload.

Once the upload has completed, the BIG-IP iHealth system may take several minutes

to process the data.

Selecting your uploaded qkview files

You can log into BIG-IP iHealth at any time to see a list of available uploaded qkview

files. You can also access this list by clicking the MyQKViews link at the top of any

page. Click on the link for the desired qkview file and the BIG-IP iHealth Viewer

overview page for that qkview file will display.

Note: You can sort the columns by any field, such as the creation date of the qkview file,

F5 case number, or the upload date and time. If you have uploaded several qkview files

to the system, sorting the columns allows you to quickly find the qkview file you are

interested in.

BIG-IP® iHealth

™ User Guide 8

Chapter 4: How do I delete my qkview files from the BIG-IP iHealth system?

In accordance with the F5 data retention policy, the BIG-IP iHealth system will

automatically delete your qkview files for closed cases one month after upload. However,

you may optionally delete your uploaded qkview file at any time. To delete a qkview

file, perform the following procedure:

1. Log in to the BIG-IP iHealth system.

2. Click the My QKViews link at the top of the page.

3. Select the check boxes next to the qkview files you would like to delete.

4. Click Remove.

A pop-up window will ask you to confirm your choice.

5. Confirm.

The BIG-IP iHealth system will immediately remove the qkview file from your My

QKViews list. Deletion from the rest of the BIG-IP iHealth system will take several

minutes, as the BIG-IP iHealth system synchronizes the request between the F5 data

centers.

Note: If you delete a qkview file that is needed to troubleshoot your open support case,

F5 Technical Support may request that you upload the file again for diagnostic purposes.

Chapter 5: How do I compare qkview files?

The BIG-IP iHealth Compare feature quickly displays all of the differences between two

qkview files taken from the same system or different systems. For example, if you make

a change to your BIG-IP or Enterprise Manager system that causes your system to no

longer work correctly, you can use the Compare feature to quickly pinpoint the issue.

You would simply upload a new qkview file and use the Compare feature to compare

the new qkview file to a qkview file taken when the system was running smoothly.

Using the Compare feature

1. Log in to the BIG-IP iHealth system.

2. Follow the instructions in Chapter 3 to upload the qkview files.

3. Click the My QKViews link at the top of the page.

4. Select the check boxes next to the qkview files you want to compare.

5. Click Compare.

diagnostics, or to influence the development of other diagnostics.

Viewing the Files menu

Under the Files menu, you can drill down into all of the configuration files, logs, and

other raw information contained in the qkview file. This information is presented in a

raw and unprocessed form. Accessing this information can help to locate issues that were

not found by the BIG-IP iHealth Diagnostics component.

To download any file to your local computer, click the name of the file you are interested

in. If a filename is grey and does not appear as an active link, then the file contains no

data. Note that due to the manner in which qkview files are generated, some information

(such as large log files) may not be included in the qkview file.

Chapter 6: How do I use the search feature?

Another way to find critical information in your qkview file is to use the search feature.

To quickly search for information, open your qkview file, enter text into the box, and

click the Search link in the upper right corner of the page. All searches are case

insensitive. Searching using regular expressions is not currently supported.

The search is specific to the navigation links on the left side of the screen. For example,

searching for a log message in the Graphs link will likely not yield any results.

Surrounding search strings with single or double quotes is not required. Including them

makes them part of the search criteria.

The Files tab provides additional search functionality. Selecting or clearing the Case

sensitive and Limit to <directory name> files check boxes enables or disables the

functions. Clearing the Limit to <directory name> files check box will revert to

searching all of the files. To display the lines that matched your search, click the down

arrow next to Show Matching Lines.

Note: Some search queries return too many results to display. Try a more specific search

string if you receive the following error message:

Your search query exceeded the maximum number of results.
