CIS-Discovery Exam Dumps - Certified Implementation Specialist - Discovery

The Application Pattern Type is a pattern that discovers applications and their dependencies by using probes and sensors1. It has two main components: the Run Order and the Identification Section2. The Run Order defines the sequence of probes and sensors that Discovery uses to find and classify CIs2. The Identification Section specifies the criteria that Discovery uses to identify CIs and their relationships2. The other options, CI Type and Operating System, are not specific to the Application Pattern Type. They are used for other pattern types, such as the Horizontal Pattern Type and the Service Mapping Pattern Type3 .

The ECC Queue tab displays the input and output messages from and to MID Servers. The default fields that are displayed on this tab are:

Topic: The topic of the message, such as Discovery, Orchestration, or MID Server.

Queue: The queue name of the message, such as input, output, or error.

Source: The source of the message, such as the MID Server name, the instance name, or the probe name.

State: The state of the message, such as ready, processed, or ignored.

Created: The date and time when the message was created.

Updated: The date and time when the message was last updated.

Some other fields that can be added to the ECC Queue tab are:

Details: The details of the message, such as the payload, the response, or the error message.

Pattern log link: The link to the pattern log file, if the message is related to a pattern execution.

CMDB CI: The configuration item that is associated with the message, if any.

Discovery schedule name: The name of the discovery schedule that triggered the message, if any.

To troubleshoot discovery issues from a discovery status in ServiceNow, the following related lists can be particularly useful:

Discovery Log- Provides detailed logs of the discovery process, helping to identify errors or issues encountered during discovery.

ECC Queue- Shows the messages and data passed between the ServiceNow instance and the MID Server, offering insights into the communication and data exchange during discovery.

Devices- Lists the devices discovered in the process, allowing for a direct view of the results and any potential issues with specific devices.

The "Running Processes" list is not typically used for troubleshooting discovery processes as it relates more to the operational aspects of the server or device rather than the discovery process itself.References= ServiceNow Discovery documentation, specifically the sections on Discovery troubleshooting and analysis, and the use of related lists for monitoring and troubleshooting purposes.

 Reconciliation rules are used to determine which data sources can update CI attributes in ServiceNow. Reconciliation rules can be static or dynamic, and they can be applied to specific CI classes, attributes, or discovery sources. Reconciliation rules can also specify the actions to take when there are unmatched values, such as removing, ignoring, or updating them1.

Discovery finds and maps dependencies for the following types of storage devices: Direct-attached storage (DAS), network-attached storage (NAS), or storage area network (SAN)1. NAS or SAN storage that is discovered via a Storage Management Initiative Specification (SMI-S) and Common Information Model (CIM) is also supported2. Discovery collects information about storage area networks from specialized devices, such as storage arrays and Fibre Channel (FC) switches, and creates specific references between the tables in the SAN3. Discovery does not support Multiple area network (MAN) or Redundant Array of Independent Disks (RAID) as types of storage devices.

A horizontal pattern is a type of Discovery pattern that discovers configuration items (CIs) and their relationships by moving across the network from one device to another. A horizontal pattern can use the Change user operation to switch from the default credentials to any other appropriate credentials for a specific device or application. This operation allows the pattern to access different types of CIs with different authentication methods.

In a discovery pattern, CI Attributes are the fields that store the information about the configuration items (CIs) that are discovered by the pattern. The Pattern Designer is a graphical interface that allows users to create and edit patterns using drag-and-drop operations. In the Pattern Designer, there are two types of CI Attributes that are available: Main pattern CI type and Related CI types. The Main pattern CI type is the CI type that the pattern is designed to discover, such as Windows Server, Linux Server, or Database. The Related CI types are the CI types that are related to the main CI type, such as IP Address, Network Adapter, or Software Installation. Users can select the CI Attributes from these types to populate the CMDB tables with the data collected by the pattern123.

A MID Server needs to have access to the install.service-now.com domain to automatically stay up-to-date with instance versions. This domain hosts the MID Server upgrade files that are downloaded and installed by the MID Server when a new version is available. The MID Server checks for updates every 24 hours by default, or when the mid.upgrade.check_interval property is set12.
