In previous versions, the commands are hard-coded and there is no option available to add or change the commands. From Denali SP3 onwards, the Administrators can copy all the pre-defined commands to a template from the existing template based on the OS flavor. Also, the Administrators have the privilege to add the required commands as per the OS and the OS flavor.

Use Case

Consider you are using Linux OS and Redhat Linux flavor. You have another machine that uses different flavor of Linux. In this case few of the pre-defined commands may not work for the different flavor. To leverage this, SummitAI provides a configurable DISCOVERY TEMPLATES page where you can add commands based on the OS flavor.

To Configure Discovery Templates:

  1. Select Admin > Advanced > Discovery & Monitoring > Discovery Templates.
  2. On the DISCOVERY TEMPLATES page, Select the Tenant on the Filters pop-up to view the list of configured Scripts.

  3. On the DISCOVERY TEMPLATES page, click the ADD NEW icon on the ACTIONS panel. The COPY TEMPLATE pop-up page is displayed.

    FieldDescription
    Template NameSpecify the name of the template.
    SOURCE
    DepartmentBy default the Global Tenant is selected to copy the pre-defined commands.
    ProtocolSelect the Protocol type from the drop-down list.
    TemplateSelect the Template from which the data should be copied.
    For WMI and SSH Protocols
    OS Platform 

    Select the OS Platform from the drop-down list. Based on the selected OS Platform, the list of available OS Flavors are displayed under the OS Flavor drop-down list. You can configure the drop-down values on the COMMON MASTERS CONFIGURATION page. For more information, see Configuring Common Masters. Also, the drop-down values are automatically captured during discovery of devices.

    For Example: 

    Consider that you selected Linux, the OS Flavors of Linux such as Red Hat Enterprise Linux, Ubuntu, Linux Mint get displayed under the OS Flavor drop-down list.

    OS FlavorSelect the OS flavor of the selected OS Platform from the drop-down list. Based on the selected OS Platform, the list of available OS Flavors are displayed under the OS Flavor drop-down list. You can configure the drop-down values on the COMMON MASTERS CONFIGURATION page. For more information, see Configuring Common Masters. Also, the drop-down values are automatically captured during discovery of devices.
    For SNMP Protocol
    Device CategorySelect the Device Category from the drop-down list. For example: Network Device, Server, Printer etc.

    Match Pattern

    Based on the selected Target OS Platform and Target OS Flavor, you can select any of the following options:

    • Exact: Select this option to discover and monitor the parameters that contains the exact Target OS Platform and Target OS Flavor names. 
      For Example: 
      Consider the specified OS Platform is Linus and OS Flavor as Red Hat Linux 4.5.0, then the discovery happens only for the Linux and Red Hat Linux 4.5.0. Following are more examples for Exact pattern:

    Parameters

    Displays the list of default parameter names. Also, you can specify the required parameters with the following details:

    • Parameter Name: Specify the Parameter name.
    • Parameter Value: Specify the value for the specified parameter.
    • Parameter Type: Select the type of parameter from the drop-down list that contains Hardware, Software, or Additional. For SNMP, the values of Parameter Type are Get and Walk.
    • Actions: Click the Actions icon to include the Parameter in the table.

    Note:

    •  icon indicates a default parameter.
    •  icon indicates user specified parameter.

    Click  icon to specify or edit the content parser logic of a specific parameter.

    Note:

    Based on the content parser configuration, the output is displayed on the JOB DETAILS page. If the content parser is not configured for a parameter, the complete output gets displayed on the JOB DETAILS page. For more information, see Discovery Dashboard.

     Content Parser

    CONTENT PARSER

    The output of the discovered device value is displayed based on the configured Parameter Name, Parameter Value, and the Content Parser scenario.

    For Example:

    Consider the configured values as follows:

    • Parameter Name as CPU
    • Parameter Value as cat/proc/cpuinfo
    • Content Parser as shown in the below screenshot:

    Now, the output discovery data displays the model name of the CPU. To get more details on other information, you can add the required Parameter Name, Parameter Value, and the Content Parser logic in the Parameters table. Also, you can configure another content parser line if the information is related to the same existing parameter.

    Note:

    If the content parser is not configured, then the complete data is displayed in a sentence without the data separation.

    FieldDescription
