ESAMON screens/ESAMAP reports:

Docker Containers

ESADOCK1 - Docker Configuration
ESADOCK2 - Docker Transaction Analysis
ESADOCK3 - Docker File System Report

Using zVPS to find information for solving issues with the Linux applications:

ESADOCK1 - Shows information about the Docker configuration.

Node - This shows the zTCP node name.

Container Index - This shows the first twelve characters of the container ID.

Container Image - This shows the Docker image name.

Container Name - This shows the container name.

ProcID - This shows the unique process id for the container.

Status - This shows the status of the container. This can be:

       Created - Created but not started
       Running - Created and started
       Restarting - The container has been restarted due to one of four restart policies - no, on-failure, always or unless-stopped.
       Exited - The process inside the container has terminated. In this state, no CPU or memory are consumed by the container.
       Paused - All the processes have been suspended for an indefinite time.
       A paused container consumes the same memory used while running but the CPU is released.
       Dead - The container is non-functioning - this happens when trying to remove the container but it can not be because some resources are still in use.

Create Date/Time - This shows the container creation date/time.

Start Date/Time - This shows the container start date/time.

Terminate Date/Time - This shows the container termination date/time.

ESADOCK2 - Shows information about the Docker transactions.

Node - This shows the zTCP node name.

Container Index - This shows the first twelve characters of the container ID.

Container Image - This shows the Docker image name.

Container Name - This shows the container name.

CPU Percent User - This shows the CPU utilization consumed by the processes of the container.

CPU Percent System - This shows the CPU utilization consumed by the kernel executing system calls on behalf of the process.

Storage Current Use - This shows the current memory usage.

Storage Max - This shows the maximum memory usage.

PageRate In - This shows the page in rate per second.

PageRate Out - This shows the page out rate per second.

Major Page Fault - This shows the major page fault rate per second - which requires the kernel to read the data from disk.

ESADOCK3 - Shows information about the Docker file system.

Node - This shows the zTCP node name.

Container Index - This shows the first twelve characters of the container ID.

Container Image - This shows the Docker image name.

Container Name - This shows the container name.

Utilization Size - This shows the size of the volume in megabytes.

Utilization Used - This shows the amount of storage used in megabytes.

Utilization Full - This shows the percentage used of the volume.

Mount Point - This shows the mount point of the volume which is preceeded by /var/lib/docker/containers.
