Solution

Follow these steps to identify and troubleshoot the cause.

WARNING
Because this is a critical alert, it is highly recommended you complete Step 1 before you try to troubleshoot the issue (Step 2 onwards).
  1. Check if an Adobe Commerce support ticket exists. For steps, refer to Track your support tickets in our support knowledge base. Support may have received a New Relic threshold alert, created a ticket and started working on the issue. If no ticket exists, create one. The ticket should have the following information:

  2. In New Relic, review disks for highest use. For steps refer to Storage tab on New Relic Infrastructure monitoring Hosts page:

    • If in New Relic you see a slow increase in disk usage, try the following options:
    • Optimizing disk space by adjusting space allocation. For steps, refer to Manage Disk space in our developer documentation. You may also need to request more disk space (contact your Adobe Account Team).
    • Clear up disk space for MySQL. Refer to MySQL disk space is low in our support knowledge base for steps.
    • If New Relic shows rapidly increasing disk usage, this could indicate that there is a problem that has caused a file to increase very quickly in a directory. Do the following checks:
  3. Check overall disk space to identify the problem by running the following command in the CLI/Terminal: df -h

  4. After you identify a directory with unexpectedly large and increasing disk usage, you need to check the affected file system. The following example shows how to check the file directory pub/media/. This is the directory Commerce uses for storing logs and big media files. However, you should run this command for any directory that shows unexpected disk usage: du -sch ~/pub/media/*

If the output from the terminal shows a file in one of these directories rapidly increasing in disk usage and you know that the file’s content is not needed, consider removing the file. If you are not comfortable taking this action, submit an Adobe Commerce support ticket.
