Question:
Have noticed that contrack_entries always reports a sawtooth pattern with a frequency of 2 minutes. The values peak to 2-3x and come down I,e for a given host connection tracking entries ramp up to 6000 from 2000 in 2 mins and fall back.
I don’t get any info on this behavior. I am planning to run a nodejs powered web socket service in Kubernetes that requires to have a persistent backend connection. Need a clarification if this will have any impact on the service
