Configuring a managed host

Configure a managed host to specify which role the managed host fulfills in your deployment. For example, you can configure the managed host as a collector, processor, or a data node. You can also change the encryption settings, and assign the host to a network address translation (NAT) group.

To make network configuration changes, such as an IP address change to your QRadar® Console and managed host systems after you install your QRadar deployment, use the qchange_netsetup utility. If you use qchange_netsetup, verify all external storage which is not /store/ariel or /store is not mounted. For more information about network settings, see the Installation Guide for your product.

Before you begin

Ensure that the managed host has the same IBM® QRadar version and fix pack level as the QRadar Console that is used to manage it. You can't edit or remove a managed host that uses a different version of QRadar.

If you want to enable Network Address Translation (NAT) for a managed host, the network must use static NAT translation. For more information, see NAT-enabled networks.


  1. On the navigation menu ( Navigation menu icon ), click Admin.
  2. In the System Configuration section, click System and License Management.
  3. In the Display list, select Systems.
  4. Select the host in the host table, and on the Deployment Actions menu, click Edit Host.
    1. To create an SSH encryption tunnel on port 22 for the managed host, select the Encrypt Host Connections checkbox.
    2. To configure the managed host to use a NAT-enabled network, select the Network Address Translation checkbox, and then configure the NAT Group and Public IP address.
    3. To configure the components on the managed host, click the Component Management settings icon (settings icon) and configure the options.
    4. Click Save.
  5. On the Admin tab, click Advanced > Deploy Full Configuration.
    Important: QRadar continues to collect events when you deploy the full configuration. When the event collection service must restart, QRadar does not restart it automatically. A message displays that gives you the option to cancel the deployment and restart the service at a more convenient time.
