Discovery configuration Configure the elements that Discovery needs to investigate your network, such as credentials, schedules, and IP addresses. Introduction to Discovery configurationDiscovery extracts information from computers and other devices.Discovery schedulesA Discovery schedule determines what the discovery run 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.Import IP ranges into Discovery schedules with import setsThe most efficient method of entering large numbers of IP networks into Discovery schedules is through the use of import sets.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.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 interface (Discovery > Status) displays all the details of a Discovery.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.
