iHealth configuration overview

If you have configured your system with F5 iHealth credentials, the iHealth upload feature uploads QKView files, by default, directly to F5 iHealth at ihealth2.f5.com. If the host does not have internet access to reach f5.com, you can configure the system to use a web proxy to upload the QKView file to F5 iHealth.

Configure iHealth credentials and web proxy from the webUI

Before you can log in to the new iHealth system, you must first generate API token credentials at ihealth2.f5.com/qkview-analyzer/settings.
The iHealth upload feature uploads QKView reports, by default, directly to F5 iHealth at ihealth2.f5.com. You can configure iHealth credentials from either the system controller or chassis partition webUI. If the host does not have internet access to reach f5.com, you can configure the system to upload QKView files to iHealth using a web proxy server.
  1. Log in to the VELOS system controller webUI or the chassis partition webUI using an account with admin access.
  2. On the left, click
    DIAGNOSTICS
    iHealth Configuration
    .
    The iHealth Configuration screen displays.
  3. In the Credentials area, for
    Client ID
    , enter your client identifier.
  4. For
    Client Secret
    , enter the secret associated with the client identifier.
  5. Configure a proxy server, if needed.
    If you are not using a web proxy server, leave these fields blank.
    1. In the Proxy Server area, for
      Server URL
      , enter the web proxy server URL, including the port number.
    2. For
      Username
       and
      Password
      , if the web proxy server requires credentials, enter the user name and password.
  6. Click
    Save & Close
    .
  7. Click
    OK
     when the Update iHealth Configuration popup displays.
Now you can generate QKView files and upload them to F5 iHealth.

Configure iHealth server from the CLI

The iHealth upload feature uploads QKView files, by default, directly to F5 iHealth at ihealth2.f5.com.You can configure iHealth credentials and upload QKView files from the CLI. If the host does not have internet access to reach f5.com, you can configure the system to upload QKView files to iHealth using a web proxy.
  1. Connect using SSH to the system controller floating management IP address or chassis partition management IP address.
  2. Log in to the command line interface (CLI) of the system controller or chassis partition using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  3. Change to config mode.
    config
    The CLI prompt changes to include
    (config)
    .
  4. Configure the iHealth server address.
    system diagnostics ihealth config server <
    ihealth-url
    >
    In this example, you configure the default iHealth server address: 
    syscon-1-active(config)# system diagnostics ihealth config server
(<string>) (https://ihealth-api.f5.com/qkview-analyzer/api/qkviews?visible_in_gui=True): 
  https://ihealth-api.f5networks.net/qkview-analyzer/api/qkviews?visible_in_gui=True
  5. Configure the iHealth authentication server address.
    system diagnostics ihealth config authserver <
    auth-server-url
    >
    In this example, you configure the default iHealth authentication server:
    syscon-1-active(config)# system diagnostics ihealth config 
  authserver https://api.f5.com/auth/pub/sso/login/ihealth-api
  6. Configure your iHealth server credentials.
    system diagnostics ihealth config username <
    username
    > password
    In this example, you configure the username jdoe and a password:
    syscon-1-active(config)# system diagnostics ihealth config username jdoe password
(<AES encrypted string>): *************
  7. Commit the configuration changes.
    commit

Configure iHealth web proxy from the CLI

The iHealth upload feature uploads QKView reports, by default, directly to F5 iHealth at ihealth2.f5.com.You can configure iHealth credentials from either the system controller or chassis partition CLI. If the host does not have internet access to reach f5.com, you can configure the system to upload QKView files to iHealth using a web proxy.
  1. Connect using SSH to the system controller floating management IP address or chassis partition management IP address.
  2. Log in to the command line interface (CLI) of the system controller or chassis partition using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  3. Change to config mode.
    config
    The CLI prompt changes to include
    (config)
    .
  4. Configure the proxy server.
    system diagnostics proxy config proxy-server <
    ip-address:port
    >
    In this example, you configure a proxy server using the IP address 192.0.2.20 and port 3128: 
    syscon-1-active(config)# system diagnostics proxy config 
  proxy-server http://192.0.2.20:3128
syscon-1-active(config)# commit
  5. Configure the proxy server credentials, if needed.
    system diagnostics proxy config proxy-username <
    username
    > proxy-password <
    password
    >
    The proxy username and password configuration elements contain the credentials for the proxy server. If the proxy server does not require authentication, these values are ignored.
    In this example, you configure the username "myname" and a password:
    syscon-1-active(config)# system diagnostics proxy config 
  proxy-username myname
syscon-1-active(config)# system diagnostics proxy config proxy-password
(<AES encrypted string>): ******
  6. Commit the configuration changes.
    commit
Now you can generate QKView files and either upload them to F5 iHealth or manage the files locally.

System reports (QKView) overview

If you have any concerns about your system operation, you can use the QKView utility to generate a system report to collect configuration and diagnostic information from the system.
The QKView file contains machine-readable (JSON) diagnostic data and combines the data into a single compressed tar.gz format file. You can upload the QKView file to F5 iHealth at ihealth2.f5.com, where you can get help verifying proper operation of the system, understanding and troubleshooting any issues you might be having, and ensuring that the system is operating at its maximum efficiency.
When generating a QKView from the CLI, you use the same command to generate a QKView file at both the system/chassis and the chassis partition levels. To generate a QKView from a remote system, the commands differ slightly.

Generate system reports (QKView) from the webUI

If you want to upload a QKView file to the F5 iHealth server, your
VELOS
 system must have DNS configured and have internet access to these services using the HTTPS/443 remote service/port:
  • api.f5.com
  • ihealth-api.f5.com
You can generate a QKView file from either the system controller or chassis partition webUI. Both reports contain diagnostic information, such as configuration data, log files, time series statistics, and platform information.
  1. Log in to the VELOS system controller webUI or the chassis partition webUI using an account with admin access.
  2. On the left, click
    DIAGNOSTICS
    System Reports
    .
    The System Reports screen displays. A list of QKView files that were previously generated are shown with any reports that were uploaded to iHealth.
  3. To generate a system report, click
    Generate QKView
     in the upper right corner of the screen.
    The Generate QKView box displays these additional options:
    Option
    Description
    Filename
    Specify a name for the file to which QKView file data is written. The default filename is <
    system-name
    >.tar.
    Timeout Value
    Specify the time in seconds after which to stop QKView file data collection. The default value is 0, which indicates no timeout.
    Max File Size
    Exclude all files greater than the specified size (in MB). The range is from 2 MB to 1000 MB. The default value is 500 MB.
    Max Core Size
    Exclude core files greater than this size (in MB). The range is from 2 MB to 1000 MB. The default value for maximum core size is 25 MB.
    Exclude Cores
    Specify whether core files should be excluded from the QKView file. The default is to include core files.
    The system runs many commands to collect the diagnostic information, so generating the report might affect its performance.
    It takes a few minutes for the system to finish creating the report and list it on the screen. The QKView Status changes to
    File generated successfully
     when it is done.
  4. To upload the report to the F5 iHealth server, select the check box next to the QKView name and click
    Upload to iHealth
    .
    For information on uploading the report using a web proxy, see "Configure iHealth uploads and web proxy from the webUI".
    The QKView tar file uploads to iHealth, where you can get help to diagnose the health and proper operation of the system. You can view the report at ihealth2.f5.com.
  5. To delete a QKView file, select it and click
    Delete
    .

Generate system reports (QKView) from the CLI

You can generate a QKView file from either the system controller or chassis partition CLI. The report contains diagnostic information, such as configuration data, log files, and platform information.
  1. Log in to the command line interface (CLI) of the system controller or chassis partition using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  2. List existing QKView files.
    show system diagnostics qkview
  3. Generate a QKView file.
    system diagnostics qkview capture exclude-cores [ false | true ] filename <
    filename
    > maxcoresize <
    size
    > maxfilesize <
    size
    > timeout <
    time
    >
    These options are available:
    Option
    Description
    exclude-cores
    Specify whether core files should be excluded from the QKView file. The default is to include core files.
    filename
    Specify a name for the file to which QKView file data is written. The default filename is
    <
    system-name
    >.qkview
    .
    maxcoresize
    Exclude core files greater than this size (in MB). The range is from 2 MB to 1000 MB. The default value for maximum core size is 25 MB.
    maxfilesize
    Exclude all files greater than the specified size (in MB). The range is from 2 MB to 1000 MB. The default value for maximum file size is 500 MB.
    timeout
    Specify the time in seconds after which to stop QKView file data collection. The default value is 0, which indicates no timeout.
    In this example, you generate a QKView file named
    client-qkview.tar
     that excludes core files and sets a timeout value of 0 (zero), which indicates no timeout: 
    syscon-1-active# system diagnostics qkview capture filename 
client-qkview exclude-cores true timeout 0
result  Qkview file client-qkview is being collected
return code 200
  4. Check the status of the QKView generation process.
    system diagnostics qkview status
    A summary similar to this example displays:
    syscon-1-active# system diagnostics qkview status
result  {"Busy":true,"Percent":12,"Status":"collecting","Message":"Collecting Data","Filename":"client-qkview"}

resultint 0
  5. Delete a QKView file.
    system diagnostics qkview delete filename [<
    hostname
    >:]<
    filename
    >
    In this example, you delete a QKView file named "c3-test.tar.canceled" on the local system:
    syscon-1-active # system diagnostics qkview delete filename c3-test.tar.canceled
    In this example, you delete a QKView file named "c3-test.tar.canceled" on a remote system with the hostname "controller-2":
    syscon-1-active # system diagnostics qkview delete filename controller-2:c3-test.tar.canceled
    When deleting a file from a remote system, append the hostname before the file name, using a colon (:) to indicate where the QKView file is stored.
Next, you upload the report to the iHealth server.
