List of Discovery probes A wide variety of probes exist for the Discovery application to detect elements on your network. These probes are included with the Discovery application. The PPP script designation in the table indicates whether the probe includes a probe post-processing (PPP) script that runs on the MID Server. The PPP script transforms probe results into a JSON string and returns the string to the ServiceNow instance for sensor processing. To view probes and their descriptions, navigate to Discovery Definition > Probes. CIM probeThe CIM probe uses WBEM protocols to query a particular CIM server, the CIM Object Manager, for a set of data objects and properties. Horizontal Pattern probeDiscovery uses the Horizontal Pattern probe to launch patterns for horizontal discovery.PowerShell probeThe PowerShell Probe executes PowerShell V2 scripts on the MID Server host.SCPRelay probeThe SCP Relay Probe copies a single file or the contents of a directory from one host to another, using the MID Server as a relay.SNMP probesThe SNMP probes use the SNMP protocol to query a particular device for a list of OIDs, which are then traversed and the results passed back to the sensors.SSHCommand probeA probe using the ECC queue topic name SSHCommand executes a shell command on the target host, and returns the resulting output to the sensor.WMIRunner probeWMI Runner is a probe type that fetches data from Windows operating systems via the Windows Management Instrumentation (WMI) interface.Port probesPort probes are used in Discovery by the Shazzam probe to detect protocol activity on open ports on devices it encounters.
