  2. Click on the diagnostic scripts tab from the left-hand menu
  3. Click the browse button under Upload diagnostic script to vSZ , select the KSP file attached, and upload it.

Upon successful upload, the script ("script name ") will be visible in the section below the "upload" section.

Step 3: Execute the script on the vSZ node's CLI:
