USM Anywhere receives log data from external data sources: devices, applications, or operation systems. If that data is not automatically matched with an BlueApp through hints (see Data Sources: Auto Discovered or Not), you must manually associate the BlueApp with an asset in USM Anywhere. There are two methods for creating these associations: By assigning one or more assets to the BlueApp (this document). By adding one or more BlueApps to the asset. See Adding BlueApps to an Asset for details. You can use a combination of these methods to ensure that USM Anywhere can identify the correct BlueApps for the log data it receives from an asset.
Important: Assigning an BlueApp to an asset disables the usage of hints for the logs coming from this asset; therefore, USM Anywhere only uses the assigned BlueApps to parse and normalize those logs.If you use a log-forwarding software (such as Splunk or Loggly) to send logs to USM Anywhere, LevelBlue recommends that you use at least two such forwarders: one forwarder for all the auto-discoverable BlueApps, and the other for the non-auto-discoverable BlueApps. In the latter case, you must create an asset in USM Anywhere to denote the forwarder and assign it to the non-auto-discoverable BlueApps. This ensures that USM Anywhere uses the correct BlueApp to parse your logs.

To remove an asset from an BlueApp
  1. Go to Data Sources > BlueApps > Available Apps.
  2. Look for the BlueApp from which you want to remove the asset and click the tile.
  3. Click the icon.
  4. Click Accept to confirm.
To modify an assigned format
  1. Go to Data Sources > BlueApps > Available Apps.
  2. Look for the BlueApp you want to modify and click the tile.
