Discovering assets

Hyperview’s agentless auto-discovery detects and monitors devices across your IT infrastructure. This includes servers, network devices, environmental monitors, PDUs, power meters, air handling systems, and any other assets that are connected to your network.

The term discovery refers to a single auto-discovery configuration that will scan one or more IP addresses in your network using a certain number of protocols. For example, you can create a discovery to scan IP addresses 192.168.10.15 through 192.168.10.60 using the SNMP v3, IPMI, and SSH protocols, and runs every day at 5:30 PM (UTC).

Upon running the discovery, the Data Collector software will automatically find and organize devices that are connected to the specified IP addresses. Moreover, the application will continuously review and optimize the data to create up-to-date virtual representations of the assets (“digital twins”), complete with device specifications and visual renderings based on the Hyperview Product Catalog.

Before you start

  • Please note that only Administrators have access to discovery features in Hyperview.
  • You must set up Data Collectors before you can discover assets.

Adding a discovery

Adding a discovery will create a base record to discover assets to a specific location and using a specific Data Collector. You must subsequently update the discovery’s details to specify IP addresses, protocols, and other details. If the Data Collector is retired in future, another existing Data Collector must be assigned in its place.

  1. Go to Discoveries → Overview → Add.
  2. Enter details as follows:
  • Provide a Name for the discovery.
  • Specify the Data Collector that will be used.
  • Specify the Location where the newly discovered assets will be added.
  • Specify the Discovery Type (General, VMware, or IxOS), or leave as default (General).
  1. Click Create.

Note

By default, discoveries are sorted alphabetically in the Discoveries → Overview grid. However, upon creation new discoveries will appear as the last entry in grid. If the grid spans multiple pages, the new discovery will appear as the last entry on the last page.

Updating discovery details

  1. Click the Details button for the discovery in the Discoveries grid. The Basic Settings page will open.
  2. Proceed to configure the discovery as per the following subsections. At a minimum, you will need to specify IP addresses and protocol credentials.

Updating basic settings

The Basic Settings page lets you update the base record for the discovery. You can:

  • Update the Discovery Name
  • Update the Data Collector for the discovery
  • Update the Location where discovered assets will be added
  • Toggle a setting to “Monitor newly discovered assets by default”

Click the Save button to retain your changes.

Note

You cannot update the Discovery Type (General, VMware, or IxOS). Updating the Location value will have no effect on already-discovered assets — they will remain at their current location.

Adding IP addresses

Click the IP Addresses tab to open the IP Addresses page for your discovery. By default, no IP addresses are added to new discovery records.

You can specify IP addresses to include or exclude from your discovery as follows:

  1. Click on the corresponding Add button.
  2. Provide details as follows:
  • Specify the Type (Single IP Address, IP Range, CIDR Range, or List).
  • Provide a Description (optional).
  • Specify the IP address or range using relevant Type-specific fields.

Note

We recommend keeping the total number of IP addresses in a discovery under 1,000 to keep the discovery runtime manageable. It is also best practice to separate discoveries by asset type and protocol to keep discoveries organized and simplify any troubleshooting scenarios.

Updating protocol settings

Click Protocol Settings → Protocols to open the Protocol Settings page. By default, all discovery-supported protocols are enabled.

  • To disable a certain protocol, click the toggle switch.

To open protocol-specific settings pages for IPMI, SNMP, SSH, or WMI, click on the corresponding Edit button on the Protocol Settings page. Alternatively, click on the page link from the Protocol Settings dropdown. You will need to provide protocol access credentials.

  • Click Add → provide protocol-specific credential values → Save.
  • Alternatively, click Add → Existing Credential → select credentials → Save.

Tip

You can also add protocol credentials from Discoveries → Credentials, which you can select for subsequent discoveries.

Relevant port numbers are automatically added for each protocol upon discovery creation (note: not relevant to WMI as it uses dynamic ports).

  • To add a different port, click Add → enter port number → Save.
  • To delete a port, click Delete → Delete.

Adding a discovery schedule

Click the Schedules tab to open the Schedule page, which lets you specify a runtime schedule for your discovery. By default the Schedule value is set to None, which implies that the discovery will only be run manually.

  1. Select Daily, Weekly, or Monthly from the Schedule dropdown.
  2. Provide values and click Save.

Note

Discovery runtime schedules are in UTC.

Deleting a discovery

  1. Go to Discoveries → Overview.
  2. Click the three dots on the discovery row → Delete → Delete.

Running a discovery

Once you have added and configured a discovery, you can run it manually.

  1. Go to Discoveries → Overview.
  2. Click Run Now from the discovery row.

The discovery’s Status will update in the grid. Once it has finished running, you can look up the discovery report.

Tip

You can also run the discovery and see the run status from the Discovery Report page (Discoveries → Overview → Details → Discovery Report).

Reviewing a discovery report

Discovery reports are automatically generated for completed discoveries at Discoveries → Overview → Details → Discovery Report. The page includes a comprehensive list of all run records for the specific discovery.

  • To look up a specific discovery report, click the corresponding Details button in the report grid.

Each discovery report mentions execution specifics, including error codes for Hyperview Support. You can also review a searchable list of discovered assets and their discovery status (New, Changed, or Unchanged).

Tip

Double-clicking a discovered asset in the report grid opens the asset’s Dashboard page. To see an asset-specific discovery report for the asset (across all existing discoveries), go to Information → Discovery Report.
