Using sosreport

Before you begin to use sosreport, log into the node with the OS username and password that you created during the installation process. Once you are successfully logged in, use sudo -i to switch to root access.

Generating a report

To generate a basic report with default settings, run the command on the command line:

$ sosreport

You will be prompted to confirm that you want to generate the report. Press Enter to continue.

At the prompt, enter your first initial and last name. If you have been assigned a case number by your Rackspace support representative, enter it at the prompt.

Please enter your first initial and last name [ctrl]: jdoe
Please enter the case number that you are generating this report for: 1234

When the report is complete, the utility will display a message showing you where the report tar.xz file has been saved and the checksum for the report.

Your sosreport has been generated and saved in:
  /tmp/sosreport-jdoe.1234-20120907125725.tar.xz

The checksum is: acfcceaa72242483edece9e3b97687f1

You can now send the .tar.xz file to Rackspace Support.

If required, you can run sosreport with additional reporting options. For example, the --diagnose option includes diagnostic options, and the --report option generates an html-formatted list of the files copied in the report. Include additional options if requested by Rackspace Support.

Depending on your issue and the instructions of Rackspace Support, you may need to disable or enable certain plugins when the report is generated. To view a full list of the plugins, use sosreport -l. The output will be similar to the following example.
