Export docker stats to a file

May 01, 2023 · 1 min read · Post a comment

Exporting containers resource usage data to a file for a later debugging session is a good thing to have, as you don’t want to get SSH timeout-ed. So, here’s how to export Docker containers CPU, memory, Disk I/O, PIDs and such to a file.

Prerequisites

  • Docker

Solution

Step 1. Just run the following command to export all running containers resource usage in a json format:


docker stats --no-stream --format "{{ json . }}" > containers-stats.json

Note: This command will result only in pulling the first result. However, you could format and filter which resources to be displayed to your liking.

Step 2. Move the file out of the remote server for a possible debugging session.
