Discovery configuration Configure the elements that Discovery needs to investigate your network, such as credentials, schedules, and IP addresses. Discovery can run on a regular, configurable schedule or can be launched manually. A discovery over a specified IP address range which tells the Discovery application which specific devices to investigate. To retrieve useful information, Discovery needs credentials (usually a user name and password pair) for devices within a particular range so that Discovery can connect to and run various probes on the devices it finds. Discovery compares the devices it finds with configuration items (CI) in the CMDB and updates any matching devices. If Discovery does not find a matching CI in the CMDB, it creates a new CI. Use guided setup for MID Server and DiscoveryDiscovery guided setup provides a sequence of tasks that help you configure Discovery on your ServiceNow® instance.Set up Discovery manuallyIf you are not using Guided Setup, you must perform several configuration steps manually to activate the application, set up the MID Server, and then set up Discovery.Discovery propertiesDiscovery properties allow you to control several aspects of the horizontal discovery process.Change the Discovery source nameYou have the option of changing the source name of discovery results. You might want to do this if you have another discovery application running on your network and want to have customized identifiers.Discovery schedulesA Discovery schedule determines what the discovery will search for, when it will perform the discovery, and which MID Servers the discovery will use.Discovery domain separationConfiguration item (CI) data that Discovery collects can be separated into domains. Network DiscoveryNetwork Discovery discovers the internal IP networks within your organization.SNMP support for DiscoveryDiscovery supports SNMP versions 1, 2c, and 3. Discovery uses version 1 and 2c by default. You must enable support for version 3. Discovery and SCCM togetherUse these guidelines to avoid common issues when you use Discovery and System Center Configuration Manager (SCCM) together.Discovery device classificationAfter it detects active devices in your network using a port scan (Shazzam probe), ServiceNow Discovery attempts to classify the devices so that it can gather additional information. ServiceNow Discovery launches classify probes that query devices to find out such things as operating system and version information. Discovery classification parametersEach type of Discovery classify probe (Windows, UNIX, SNMP, etc.) returns a unique set of parameters that contains classification information.Discovery identifiersWhen Discovery finds a device in your network, it makes an effort to determine if the device already exists in the CMDB.Discovery process classificationProcess classification in Discovery tracks services, such as database servers, running on computer CIs in your ServiceNow instance. Discovery statusThe Discovery status provides a summary of a Discovery launched from a schedule. You can also cancel a Discovery that is in progress from the status form.Discovery logsThe Discovery Log and the Horizontal Discovery Log display the activity that takes place during a discovery. Use the logs to debug failed discoveries. Discovery timelineA Discovery Timeline generates a graphical display of the Discovery Status records for a Discovery, including information about each probe and sensor running.Discovery configuration consoleUse this console to configure what Discovery data the system allows in the CMDB.Discovery customizationYou can customize how Discovery works in your environment.
