Run Network Discovery

Device Discovery and Test Discovery

The Discovery Sessions page searches a network and discovers devices and tests.

For four monitor types—ping, snmp, wmi, port—discovery includes the concept of test discovery. Test discovery scans a device to identify what metrics are supported on that specific device. For example, scanning a router using SNMP returns tests related to interfaces, system resources, etc. In contrast, a linked device template or static device template only creates the tests you specify. No actual scan against the device is performed.

Note: You can perform test discovery for additional monitor types using the Perform auto-discovery of supported (*) test types option on the Add Standard Tests page.

Discovery sessions:

• Can automatically provision discovered devices with tests and start monitoring them immediately.
• Can be scheduled on a recurring basis.
• Should be limited to class-C networks instead of class-B or larger.

Automation Profiles

Automation profiles are new functionality that enable you to customize tests automatically during discovery and rediscovery. The default settings assigned to tests are overridden, based on the criteria you provide in automation profiles. For more information see Automation.

Prerequisites

Discovery requires the appropriate shared credentials be defined for the networks you want to scan.

Procedure

1. Navigate to the Administration > Discovery page.

• A list of existing Discovery sessions displays.

1. Click the add icon, then click the Network Discovery icon.

   

The Create Discovery Session dialog displays.

1. Enter the following values:

• Organization
• Discovery Name - Enter a name.
• Discovery Location - Your DGE extension was assigned a unique location when it was installed. Select it from the drop-down list. Most private networks use the same range of IP addresses. This is how Traverse identifies which network you want to run Network Discovery on.
• Discovery Type - Network
• Network Scan Range - Enter a network subnet starting value followed by the network mask. Example: 192.168.1.0/255.255.255.0. The DGE extension you installed must have network access to the range of IP addresses you specify.
• Perform Discovery on a Schedule - If checked, enter the number of intervals to wait between recurring discovery session runs.
• Start Monitoring Discovery Immediately - If checked, newly discovered devices are provisioned with tests, becoming managed assets, and begin being monitored immediately. If unchecked, devices are discovered but not yet provisioned.

1. You can now click Apply or...
2. Click Advanced to enter values in these optional fields.

Note: Ignore these advanced features for your first run of network discovery.

• SNMP Community Strings/Credentials - Optionally toggle each SNMP credential to include or exclude it from the discovery session.
  • Bolded text means the credential is included.
  • Unbolded text means the credential is excluded.
• VMware Hypervisor Credentials - Optionally enter a VMware credential to discover additional information about VMware hypervisors.
• Filter by Device Type
• Physical Connectivity - Topology
  • Discover new devices and new/updated topology
  • Update topolog information for provisioned devices only
