Re: Huge daily outbound network traffic


Are you sure you don’t have an outside process that is doing an export , Spark job, non AWS managed backup process ?

Is this network out from Cassandra or from the network?

Hi,
I have a 3 node Cassandra cluster (version 3.11.1) on m4.xlarge EC2 instances with separate EBS volumes for root (gp2), data (gp2) and commitlog (io1).
I get daily outbound traffic at a certain time everyday. As you can see in the attached screenshot, whiile my normal networkl oad hardly meets 200MB, this outbound (orange) spikes up to 2GB while inbound (purple) is less than 800MB.
There is no repair or backup process giong on in that time window, so I am wondering where to look. Any idea?
