Admin Guide: Create a support diagnostic file

  1. Last updated
  2. Save as PDF

In some cases, Interana Customer Support will need more information about your cluster to resolve a problem. The support diagnostic file gives Support information about how your instance is configured and how it has been operating up to the point that when you created the file.

The diag command collects information about your Interana environment, including configuration information. It collects information from the machine such as server specifications, OS version, and file system information. It also collects information about the Interana application, such as application configurations, Interana log files, and cluster metadata.

Creating the diagnostic file

Run the following command on a node in your Interana cluster:

sudo /opt/interana/backend/deploy/debugdump.py

This creates a compressed diagnostic file of the logs from that node. 

The script will print the location of the completed diagnostics file. For example:

Interana diagnostics file successfully created, please include the following file with your support request:

/tmp/interanadiag1496858597.tar.gz
