Initial configuration

When you configure the system for the first time, you must set up the DNS server and enable the naming service. This ensures that BMC Atrium Discovery can resolve hostnames correctly. You can also configure mail settings to enable the appliance to send e-mail reports about the status of the appliance.

By default, the appliance uses DHCP to obtain an IP address. If you need to configure your appliance to use a static IP address, specify a hostname for it, or change localization settings you need to access the command line. For information on those tasks, see the following sections:

Viewing or setting the appliance identification

You can view or set details of the appliance identity, support information (displayed in the Help drop-down on each BMC Atrium Discovery page), and read-only information on the appliance software and hardware configuration. This includes information about whether the appliance is correctly specified for its intended use.

Consolidation and Scanning Appliances

You cannot change the name of an appliance if it is configured as a consolidation or scanning appliance. See Consolidation for more information.

To view or edit the appliance identification:

  1. Click Administration.
  2. From the Appliance section, click Configuration > Identification.
    The Identification page displays details of the appliance identity, support information, software and hardware.
  3. Edit the fields that you want to change.
    The following fields can be edited:

    Field name

    Description

    Appliance

    Name

    The name of the appliance.

    Description

    A description of the appliance.

    Admin Email

    An e-mail address for the person or group responsible for the administration of the appliance.

    Banner color

    The color for the top banner in the user interface. Setting a banner color makes it easy for users in the field to identify the appliance they are using for various purposes (for example, development, test, and production environments). The appliance name is displayed on the colored banner.
    See Configuring the banner color for more information.

    Support

    Support URL

    The URL to use in the help drop down.

    Support URL Title

    The title for the support URL.

    Support URL Label

    The label for the support URL.

    Support URL Description

    The descriptive text label for the support URL.

Viewing the appliance specification

From the user interface you can view the appliance specification table, which displays the amount of CPU, RAM, SWAP, and DISK resources used by various classes of appliance deployments (such as Proof of Concept, Baseline, Datacentre, and Consolidated Enterprise).

The appliance specification table is primarily aimed at Virtual Machine deployments of BMC Atrium Discovery and shows the minimum resources required for adequate performance. For installation on hardware platforms, which are generally intended for high performance or capacity deployments, or for consolidation appliances, a higher specification is recommended. See Installing BMC Atrium Discovery for more information.

To view the appliance specification:

  1. Click Administration.
  2. In the Appliance section, click Configuration > Identification.
    The Appliance Configuration page displays the following sections:
    • Appliance
    • Support
    • Software
    • Hardware

At the bottom of the Hardware section, the application specification table displays the number of discovered Operating System Instances, and the amount of processor, memory, swap space and filesystem resources detected. Also displayed is the threshold value of these parameters for each class of deployment.

If the appliance does not have sufficient resources for one or more classes of appliance deployment, the following types of messages are displayed:

  • Message at the top of the application specification table: Specifies which resources do not meet the minimum resource specification. For example, if sufficient resource is not available for DISK, the warning message Below minimum specification (Disk Capacity) is displayed.
  • Warning message at the bottom of the application specification table: Specifies that the appliance has insufficient resources and points to the documentation link for information about hardware specifications.

In the application specification table, the classes of the appliance deployment that do not meet the minimum hardware specification are highlighted in red. The classes of appliance deployment that meet or exceed the respective minimum hardware specification are highlighted in green.

See the Configuring the Virtual Appliance section for more information about classes of appliance deployment and related topics.

Viewing network interface and routing settings

You can view details of the network interfaces and routing details configured on the appliance.

  1. Click Administration.
  2. From the Appliance section, click Configuration > Interfaces & Routing.
    The Interfaces & Routing page displays details of the configured interfaces and configured routes.

Configuring name resolution settings

  1. Click Administration.
  2. From the Appliance section, click Configuration > Name Resolution.
  3. In Search, enter the name of the domain to be searched.
  4. In Name Servers, enter the IP address of the name server.
    Multiple IP addresses can also be specified, separated by a space.
  5. New in version 8.3 SP2. From the Time Out drop-down, select the required time out for DNS requests. This can be any value between 1 and 10 seconds. The default is 5 seconds. Larger values can affect Discovery performance and are not recommended.
  6. New in version 8.3 SP2. From the Retries drop-down, select the required number of retries after DNS look up failure. This can be any value between 1 and 5. The default is 2. Larger values can affect Discovery performance and are not recommended.
  7. Click Apply to save the changes.

Configuring mail settings

  1. Click Administration.
  2. From the Appliance section, click Configuration > Mail Settings.
  3. Select Mail Enabled.
  4. In From Address, enter the e-mail address used for sending e-mail.
  5. In SMTP Server, enter the details of the SMTP server.
  6. In SMTP Port, enter the SMTP port number.
  7. If the SMTP server requires authentication, select Required in the Authentication section. Then enter the user name and password for the SMTP server.
  8. Click Apply to save the changes.

If you configure the appliance mail server settings for an invalid mail server, using mail.send() in a pattern introduces a delay of approximately three minutes while the appliance attempts to contact the SMTP server.

Modifying JVM settings

In some unusual situations, you might encounter errors caused by JVMs running out of memory. You can adjust the amount of memory allocated to individual JVMs up to a limit of 1024MB (the default value is 512MB). You should increase the JVM memory only if directed by Customer Support in response to errors.

  1. Click Administration.
  2. From the Appliance section, click Configuration > JVM Settings.
    The JVM Settings page lists the default and current values for the minimum and maximum memory settings for each JVM.
  3. To adjust a setting, select the value from the menu in the Change To column, as shown in the following illustration.
    This diagram illustrates how to change the default JVM memory size up to a maximum of 1024 MB.
  4. Click Apply.
  5. Restart the appliance.
