Create a Discovery CI classification

A CI classification allows Discovery to discover most common operating systems, network devices, and processes.

Before you begin

Role required: admin


  1. Navigate to Discovery Definition > CI Classification.
  2. Select the type of classification to create.
  3. Click New in the list of classifications for the type you selected.
  4. Complete the form using the fields in the table.
    Table 1. Classification form fields
    Field Input Value
    Name Name of the configuration item (CI).
    OID SNMP system OID for matching this device. When the OID value matches that of an SNMP device, Discovery uses the information to populate the CMDB with the specified manufacturer, model, and classifier.
    Operator Operator for determining how to match and SNMP OID. The choices are Is and Starts with. This field is available only for SNMP System OIDs classifiers.
    Active Enables or disables this classifier. When a classifier is disabled, the system stops classification at this level and does not launch classifiers of a lower order. For example, when the classifier for Windows 2008 Server is disabled, the system stops Discovery at this point and does not launch the Windows 2012 Server classifier.
    Order Order (sequence) in which the platform runs this classifier.
    Table Table for this classification. For example, if this record classifies a Linux server, select the Linux Server [cmdb_ci_linux_server] table.
    Classifier Classification of an SNMP device, such as A10 Load Balancer. This field is available only for SNMP System OIDs classifiers.
    Relationship type Type of relationship for this classifier, such as Runs on::Runs. This field is available only for application and process classifiers.
    Match criteria Criteria that must match to classify this device. The choices areAny of the parameters or All of the parameters.
    Manufacturer Name of the manufacturer of a network device. This field is available only for SNMP and SNMP System OIDs classifiers.
    Model Model number of a network device. This field is available only for SNMP and SNMP System OIDs classifiers.
    On classification script Script that runs if classification criteria are met. Use this script to perform any special tasks after a device is classified. It is possible to use the g_probe_parameters hashmap from within a classification script to set probe parameters for any configured, triggered probes. For example, this code sets a 'node_port' parameter to 16001 for all triggered probes:
    (JS), g_probe_parameters['node_port'] = 16001; //

    Classification Criteria Criteria formed from specific parameters and the values that they must contain to match devices that Discovery finds in the network with CIs in the CMDB. For a detailed discussion of these parameters, see Discovery classification parameters.
    SNMP OID Classifications Unique "fingerprints" of all the SNMP devices that ship with the base Discovery product. Users can add OIDs for SNMP devices not in this list. This related list is available only for SNMP devices.
    Triggers probes Exploration probes that Discovery launches to gather detailed information about a CI that it has classified in the network. If you want to use patterns for horizontal discovery, add the Horizontal Pattern probe in the Probe column, and then specify your pattern in the Pattern column.
    Warning: Do not specify your pattern in Probe column. Choose the Horizontal Pattern probe, which launches the specified pattern.
    Versions Lists versions of this classifier. A new version is created whenever you modify the classifier record. To revert to a previous version, open that record and select Revert to this version under Related Links.
    This example shows a completed CI classification form with exploration probes defined. For instruction on creating probes, see Discovery probes and sensors. The probes defined here are launched when the device is properly classified, unless Discovery is configured to stop after classification.
