Splunk Cloud Universal Forwarder Network Telemetry Ingestion?

maiks1 — Thu, 02 Mar 2023 09:13:12 GMT

Hi all!

I'm currently struggling to ingest network telemetry from windows endpoints/servers into Splunk Cloud.

We've installed Splunk's Universal Forwarder on each instance. SysMon Logs and basic Windows events that you can tick in the setup of UF are also being forwarded already.

Isn't the UF also supposed to capture network data?
If that's not the case, what's best practice or what method do you use?

We want to monitor unusual spikes in network traffic and be able to see what client it is and where it's sending its data to.

I already opened 2 support tickets but I've gotten no response in over a week now. That's why I'm trying it here now.

Hope you're having a great day and thanks in advance for your help.

-Maik

The Universal Forwarder does not monitor your network. Depending on the TA installed, it can provide usage data for the network cards on the server on which it's installed, but nothing for the network in general.

Your network devices may be able to send network traffic data to Splunk (probably via syslog). You'll likely need a TA installed on your indexers and search head to properly parse the data.

Splunk Support is for break/fix issues. They won't help with learning how to use Splunk.
