You need to discover all of the devices you want to monitor with OnCommand Insight. Discovery is necessary in order to accurately track performance and inventory in your environment. Typically the majority of devices in your environment are discovered through automatic device resolution.

Note: If you are performing an upgrade and have inactive Auto Resolution rules in the system you are upgrading from, these rules will be deleted during the upgrade. To preserve inactive Auto Resolution rules, activate the rules (check the box) before the upgrade is performed.

After you install and configure data sources, devices in your environment, including switches, storage arrays and your virtual infrastructure of hypervisors and VMs are identified. However, this does not normally identify 100% of the devices in your environment.

After data source type devices have been configured, best practice is to leverage device resolution rules to help identify the remaining unknown devices in your environment. Device resolution can help you resolve unknown devices as the following device types:

Devices remaining as "unknown" after device resolution are considered generic devices, which you can also show in queries and on dashboards.

The rules created in turn will automatically identify new devices with similar attributes as they are added to your environment. In some cases, Device resolution also allows for manual identification bypassing the device resolution rules for undiscovered devices within Insight.

Incomplete identification of devices can result in issues including:
The Device resolution feature (Manage > Device resolution) includes the following tabs, each of which plays a role in device resolution planning and viewing results:
