After you install the ExtraHop Add-On for Splunk, we recommend that you install the ExtraHop App for Splunk to help you configure the ExtraHop Add-On. For more information about the Extrahop Add-On, see https://splunkbase.splunk.com/app/3938.
The ExtraHop App adds additional information to the data that the ExtraHop Add-On collects, including the IP addresses, MAC addresses, and hostnames of devices discovered by ExtraHop. The app also creates default inputs to collect metrics about HTTP, DNS, and storage activity and builds dashboards to display that information.
The app includes the following objects:
- Splunk Enterprise 7.0 or later
- The ExtraHop Add-On for Splunk.
ExtraHop firmware version 7.1.2 or later
If your Splunk Enterprise deployment is distributed, install the app on your search heads. If your Splunk Enterprise deployment is a single instance, install the app on the instance. For information about installing an app, see the Splunk Add-Ons documentation.
After you install the ExtraHop App for Splunk, you can create default dashboards and inputs for HTTP, DNS, and storage activity. Note that the saved searches included in the app do not require you to create the dashboards and inputs; the saved searches will run automatically after the app is installed.
The data inputs created by this process are configured with an interval of 300 seconds and an index of “main”. These settings can be changed by editing the data inputs using the ExtraHop Add-On for Splunk or by manually editing the inputs.conf files.
IP addresses, MAC addresses, and hostnames might not appear in Splunk when this data is missing from the “extrahop_deviceoid_lookup” KV store lookup table.
In ExtraHop Add-On for Splunk v1.1.1 and later, IP addresses, MAC addresses, and hostnames are saved to the KV Store at the time of data ingest. Additionally, the ExtraHop App for Splunk includes a saved search that retrieves this information from an ExtraHop appliance and adds the information to Splunk in case that information was not already cached.
Note: Because the saved search consumes system resources and can take a long time to run, we recommend that you run the search only when necessary.
