Discovery Configuration_General

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.

Windows Servers

Requirement	Description
Common requirements	An administrative service account: Member of local Administrators group (either domain or local) Stored in monitoring accounts (customer can manage the password) Bidirectional Ping [ICMP]: Used for the latency graph up/down alerts
Agent Based (Preferred Option)	Simple low footprint agent Only requires http/s from target to proxy Supports other functions - Asset/Proxy
Windows Management Instrumentation (Alternative Option)	WMI requires Ports 135-139 from Proxy to Target It depends on the port mapper configuration. Fixed or dynamic ports for return communications. Dynamic ports will cause more effort in secure networks.

Linux Servers

Requirement	Description
Common requirements	An administrative service account: Read only but able to run privileged commands. Bidirectional Ping [ICMP] Used for the latency graph up/down alerts.
Agent Based (Preferred Option)	Agent requires http/s from target to proxy.
Secure Shell (SSH) (Alternative Option)	SSH requires Ports 22from Proxy to Target server.

Network and Other Requirements

Requirement

Description

Account requirements

Domain Administrator credential ID is required for the Auto Discovery functionality of the Asset Management.
SSH credentials with port number shall be made available for Linux/Unix device discovery.
SNMP V2c community read only string or V3 account, password, authorization and privacy information.
Account Names and Passwords shall be stored in the Monitoring Account UI, where the passwords can be managed independent of the implementation staff.

Ports that are to be opened

All devices that require Ping:

ICMP is required from the Proxy to all the targeted systems
ICMP is required from the Summit server to the Proxy

Proxy to Summit server (in Azure cloud)

Proxy to Web server, port HTTPS [443] is required for traversing the internet.

Windows servers to proxy (with agents installed)

Port 443 https agent to proxy only
If required, port 80 can be configured.

Linux servers to Proxy (no agent is installed)

SSH port 22 linux server to proxy

Linux servers to Proxy with agents installed)

Port 443 https agent to proxy

Network devices

SNMPV2c or v3 port 161 proxy to network device.

Field Description

The following table describes the fields on the DISCOVERY page:

Field	Description
DETAILS
Monitoring Source	Lists the configured monitoring source types as Summit Server and Summit Proxy. Summit Server: It refers to the machine, where SUMMIT Suite is installed using the SUMMIT Installer. It is also referred to as SUMMIT Centralized Server. Select this option to perform the discovery from this centralized server. Proxy Server: It refers to the machine configured at a client location for sending monitored data of the client machines to the SUMMIT Server. Select this option to execute the discovery from the Proxy Server.
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.
Subnet	Type in the subnet numbers.
Protocols	The following protocols are available to select: SNMP: 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: 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: The WMI protocol is used to mainly monitor the event status that is configured in the server. SSH: 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: 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.
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.
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.
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.

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.
Notify Once Complete	If selected, after completing the discovery task an e-mail notification is sent to the Administrator.
Execute Job	Select Now to execute the job now. If you select Later to run the job later. Specify the values for the following fields: Run As User: Type in the user name. Password: Type in the password to run the job. Re-enter Password: Re-type the password. Start Date: Specify the date when the job should be started.
