Discovery Configuration

Based on the Discovery configuration, the Servers, Networks, Links, Printers, and Laptop devices in the organization can be identified. The discovered devices are saved in their respective modules. You can configure multiple subnets for a job and configure protocols, such as WMI, SNMP, SSH and Telnet to discover devices in the given subnet range. You can configure the order of execution of the protocols. After the devices are discovered, you can view the listed devices in the Scanned Result section and the devices that are not listed can be viewed in the Errors Result section.

Field Description

The following table describes the fields on the DISCOVERY page:

Field	Description
DETAILS
Discovery From (Proxy)	If you select Proxy Server in the Monitoring Source field, the Discovery From (Proxy) field is displayed. Select the Proxy device from the list to discover devices from the selected proxy server.
Job Name	Type in the job name that will perform the Common Discovery.
Type	Select the Type as Subnet. Subnet From: Type in the subnet numbers. Subnet To: Type in the subnet numbers. Select the Type as Subnet Mask. Subnet From: Type in the subnet numbers and select a CIDR value from the CIDR drop-down list. For more information on CIDR, see CIDR Notation table. Note: CIDR field is used for advanced (NMAP based) discovery configurations only to determine the Broadcast address internally. Select the Type as Active Directory. LDAP Path: Select the LDAP path from drop-down list. Enable Consider all IP Addresses till the last octet of the Subnet To check box to consider all IP Addresses specified in the range between Subnet From and Subnet To while discovering devices.
Extended Discovery	The following protocols are available to select: None: Select the None check box if there is no protocol is required. SNMP: Select the SNMP check box and the SNMP version from drop-down list. Specify the SNMP strings and the timeout (in seconds). The Simple Network Management Protocol (SNMP) is a set of protocols for managing and monitoring complex networks. if SNMP check box is selected, then SNMP Version has to be specified. Select the SNMP version from the list: SNMPV1 SNMPV2c SNMPV3 Note: SNMP V3 requires an authentication and login credentials for managing a device on the network. SNMP V3 provides important security features such as confidentiality to prevent snooping by an unauthorized source, message integrity to avoid data tampering, and authentication to validate the source. If SNMPV3 is selected, the AuthType field is displayed. Select the Authentication Type from the list: AuthNoPriv: If selected you have to specify the authentication details. You have to select the SNMP user and authentication mode( SHA or MD5) AuthPriv: If selected you have to specify the SNMP user, authentication mode, privilege password, and privilege protocol. NoAuthNoPriv: If selected authentication and privilege is not applicable. You have to select the SNMP user from the list. You can provide ping time out for each protocol. Select any one monitoring protocol option. Type in the respective protocol details, as required. WMI: Select the WMI check box, the WMI user from the drop-down list, and specify the timeout in seconds. The Windows Management Interface (WMI) is a set of extensions to the Windows Driver Model that provides an operating system interface through which instrumented components provide information and notification. Note: (a) The WMI protocol is used to mainly monitor the event status that is configured in the server. (b) New fields Software Discovery, Advanced Software Discovery, and Additional Discovery check boxes are populated when you select WMI protocol. SSH: Select the SSH check box and the SSH user from the drop-down list, Specify the SSH Port No. and the timeout (in seconds). Select the SSH check box and SNMP version SSH is used in case of other than windows OS. The Secure Shell (SSH) is a Unix Shell program for logging into, and executing commands on, a remote computer. The protocol provides secure encrypted communications between two untrusted hosts over an insecure network. Telnet: Select the Telnet check box and the Telnet user from the drop-down list, Specify the Telnet Port and the timeout (in seconds). Telnet offers users the capability of running programs remotely and facilitates remote administration. Telnet is available for all operating systems and eases integration in varied networking environments. Set Time For: In this section, you can specify the ping retry and ping timeout (in micro seconds). Thread Timeout: It is required when the multi-threaded Discovery is performed. If a thread is not discovered in one attempt, the SummitAI application retries the Discovery attempt until the time (in seconds) specified in this field. If the respective thread is not discovered within the specified time, a thread timeout error message is displayed. By default, the Thread Timeout value is 300 seconds.
Ping Protocol	The Ping Protocols are used for diagnostics (like Ping), error messages, moving data between applications, and so on. Select the Ping Protocol from the drop-down list. Note: Port 7 (TCP/UDP Ping) is used for 'echo service'. If there is any environment restriction on using ICMP based ping, TCP Ping can be leveraged.
Enable Nmap Discovery	Enable this check box to discover the devices based on the reachability of the Nmap exe followed by the selected protocol.
Nmap Exe Path	If there is no path defined for the Nmap Exe, the application considers the Root path.
Discovery Scripts	Lists the configured scripts. Select the script from the list to monitor the parameters defined in the scripts through discovery and click the ADD TO LIST button to add the selected script for execution. Select the script from the list and click the DELETE button to remove the script from the ADD TO LIST section.
Discovery SNMP	Lists the configured SNMP. Select the SNMP from the list to monitor the parameters through discovery and click the ADD TO LIST button to add the selected SNMP for execution. Select the SNMP from the list and click the DELETE button to remove the SNMP from the ADD TO LIST section.
Note: The Discovery Scripts and Discovery SNMP fields are displayed based on the selected Protocols. If a Script or an SNMP MIB is configured for the selected protocol then Discovery Script or Discovery SNMP fields are displayed respectively.
Protocol Execution Order	Allows to specify the order of protocols if more than one protocols are selected. You can move the protocol up and down to specify the order.
Add For Monitoring	If selected, you can assign a default template to the discovered servers.
Default Configuration Template	Select a default configuration template from the drop-down list.
Software Discovery	If this check box is selected, only the basic Software details are discovered. It is a WMI-based Discovery that gives data of only added and removed Software, which in turn contributes in enhancing the system performance. If this check box is not selected, the SummitAI application ignores the added and removed Software for discovery. Note: On the DISCOVERY page (Type: Subnet/Active Directory/Subnet Mask), the Software Discovery check box is displayed only after selecting the WMI check box in the Protocol field.
Advanced Software Discovery	If this check box is selected, the Application fetches the registry and provides extensive Software Discovery details. Note: On the DISCOVERY page (Type: Subnet/Active Directory/Subnet Mask), the Advanced Software Discovery check box is displayed only after selecting the WMI check box in the Protocol field.
Additional Discovery	In the traditional Hardware Discovery only the basic parameters, such as CPU, model number, memory size, serial number, and so on, are discovered. If this check box is enabled, more details of the Hardware, such as local users, services, and so on, are discovered. If this check box is not selected, the Application does not perform additional Discovery and the Hardware is discovered in a traditional way. Note: On the DISCOVERY page (Type: Subnet/Active Directory/Subnet Mask), the Additional Discovery check box is displayed only after selecting the WMI check box in the Protocol field.
ADD TO LIST	Click the ADD TO LIST button to execute the protocols. All the selected protocols are added in the table below the button.
Delete	Allows you to delete the protocol from the table. Select the check box for the protocol you want to delete and click the DELETE button.
