How to get memory details for a process and a container


(Sunilthemaster) #1


I have multiple elasticsearch containers, each running with 16 GB memory and 8 GB JVM memory.

When i run command to get memory used by container, I see its peaking with 16 GB memory whereas JVM is just even taking 8 GB

Below is memory consumption of container.

As you can see even when JVM is not even consuming 8 GB, my container is peaking at 16 GB. When I go inside container and run top command, i see this. Its just using 17% memory

Can someone please explain me

  • Where is 16GB being utilized?
  • Where is 99% memory usage coming from?
  • How can i get details of which process using up 99% memory?
