  author: princechaddha
  severity: medium
  description: |
    Ensure that Guest-Level Diagnostics feature is enabled for your Azure virtual machines (VMs) in order to gather diagnostic data useful to create notification alerts and get vital information about the state of your VM applications using advanced metrics.
  impact: |
    Not having Guest-Level Diagnostics enabled may lead to insufficient data collection for troubleshooting and lack of visibility into application performance and operational health.
  remediation: |
    Enable Guest-Level Diagnostics on your Azure virtual machines to ensure comprehensive data collection and enhance monitoring capabilities.
