Overview

SolarWinds employs the easy to use Network Sonar Wizard to aid in the discovery of nodes on your network. Before using the Network Sonar Wizard, consider the following points about network discovery:

  • The Network Sonar Wizard recognizes network devices that are already in your Orion database and prevents you from importing duplicate devices.
  • CPU and Memory Utilization charts are automatically enabled for your Windows, Cisco Systems, VMware, and Foundry Networks devices.
  • The community strings you provide in the Network Sonar Wizard are only used for SNMP GET requests, so read-only strings are sufficient.

Configure the options on the Discovery Settings view, as detailed in the following steps:
  1. Provide a Name and Description to distinguish the current discovery profile from other profiles you may use to discover other network areas.


Note: This Description displays next to the Name in the list of available network discovery configurations on the Network Sonar view.

  1. Position the slider or type a value, in ms, to set the SNMP Timeout.
    Note: If you are encountering numerous SNMP timeouts during Network Discovery, increase the value for this setting. The SNMP Timeout should be at least a little more than double the time it takes a packet to travel the longest route between devices on your network.
  1. Position the slider or type a value, in ms, to set the Search Timeout.
    Note: The Search Timeout is the amount of time Network Sonar Discovery waits to determine if a given IP address has a network device assigned to it.
  1. Position the slider or type a value to set the number of SNMP Retries.
    Note: This value is the number of times Network Sonar Discovery will retry a failed SNMP request, defined as any SNMP request that does not receive a response within the SNMP Timeout defined above.
  1. Position the slider or type a value to set the Hop Count.
    Note: If the Hop Count is greater than zero, Network Sonar Discovery searches for devices connected to any discovered device. Each connection to a discovered device counts as a hop.
  1. Position the slider or type a value to set the Discovery Timeout.
    Note: The Discovery Timeout is the amount of time, in minutes, Network Sonar Discovery is allowed to complete a network discovery. If a discovery takes longer than the Discovery Timeout value provided, the discovery is terminated.
