For information about Service Mapping commands, see [Prerequisites for performing top-down discovery using Service Mapping](https://servicenow-prod.fluidtopics.net/20BFFRIMDaojk1En5RNucg "Learn about credentials, users, and user permissions you must configure to let Service Mapping access and discover applications inside your organization private network."). For information about MID Server privileged commands, see [MID Server privileged commands](https://www.servicenow.com/docs/access?context=c_PrivilegedCommandsForMIDServer&version=yokohama&pubname=yokohama-servicenow-platform&ft:locale=en-US). ## Probe-based discovery {#discovery-command-probe-pattern__section_in4_ydz_k2c} Discovery runs several different types of commands during probe-based horizontal discovery. Some of these commands require elevated privileges to run. {#discovery-command-probe-pattern__table_uc1_rfz_k2c__entry__2} | Command/Permission | Resource | |-|-| | SSH commands requiring a privileged user | [Privileged SSH commands for probe-based discovery](https://servicenow-prod.fluidtopics.net/9zRLtV44HUO12jMk5mJ1Rw "These tables display the SSH commands run by Discovery probes during horizontal discovery.

Some of these commands require elevated privileges to run. For pattern-based discovery, you can view all the commands used by a specific infrastructure or application pattern on the ServiceNow AI Platform and validate them before running discovery. For cloud resource patterns, you can view all the required permissions in the Cloud Discovery patterns spreadsheet. {#discovery-command-probe-pattern__table_tpb_k3z_k2c__entry__2} | Action | Resource | |-|-| | View commands used by infrastructure and application patterns | * [View Patterns commands through the Discovery Patterns module](https://servicenow-prod.fluidtopics.net/eouL4CSH9SmIxBXfakMpaw "View all the commands required for an infrastructure or application pattern to verify you have sufficient permissions to run discovery.")\* * [View Patterns commands through the Command List module](https://servicenow-prod.fluidtopics.net/vMTxDCLIq35mRu6N6krExA "View and filter infrastructure or application pattern commands by various criteria, including pattern, CI type, or command, to confirm you have all the required permissions.") * [Command List form for pattern-based discovery](https://servicenow-prod.fluidtopics.net/1vUxkjdlPq3bHDKtKlc65A "The Command List form contains all commands used in discovery by infrastructure or application type patterns.") {#discovery-command-probe-pattern__ul_umh_mbj_y2c} | | Validate commands used by infrastructure and application patterns | * [Validate commands used in pattern-based discovery](https://servicenow-prod.fluidtopics.net/tJclIOdpx59diE4aaqewew "Validate pattern commands to verify that the MID Server can successfully run them.
