I have a Kubernetes Cluster running with 3 nodes setup. Things were running smooth but from 27th March onwards, I see a sudden spike in Outgoing Max going as high as 1 GB/s which is leading to massive Public Bandwidth usage for the droplet. Please help me dignose this.

Hello,
Is it only the bandwidth that has increased or is it also the CPU and memory?
I could suggest checking a few things:
-
Check your logs to see if there is any suspicious amount of traffic hitting the cluster
-
Check your network connections using
netstat -cWplant -
Use
lsof -i |grep -v 'localhost'to check all open files matching an internet address -
Use
ntopto monitor the network activity on a process level
Best,
Bobby
