Optimising CPU + RAM usage on Universal Forwarder

Hello guys,

I've been looking around in the questions and most of them are about forwarders causing High CPU because of some bug or some misconfiguration. My questions is about optimising and tweaking a universal forwarder that is working well in order to reduce its CPU impact.

So anyone who has tips and tricks to share it will be very much welcome. Even if you have system level tips for linux/windows it's also welcome!

Best regards,
David

I'm not sure there is a prefect answer for your question. By default, the fwd is designed to have a very limited impact on the system. You can limit the inputs to the ones that match your needs.
You might also look at windows system features.

Of course, you can monitor CPU usage in Splunk 🙂

Hi David,

Do you have any specific issues ? On which system ? When collecting what kind of data ?
Can you give some details ?

Hello Mathieu, hope you're well 🙂

I have FWDs running on windows DC and I want to set limits to make sure that they never go over 5% CPU even if that means slowing down log collection.
Any idea on how that could be done ?
Cheers,
David
