This alert identifies a GCP Persistent Disk with critically low storage capacity. It triggers when the minimum provisioned size across all your disks falls below a predefined threshold (typically set to 3GB or another value you define). Customization Guidance: Threshold: The default threshold is set at a specific value (e.g., 3GB). You can adjust this based on your storage needs and acceptable usage levels. Applications with large data requirements might necessitate a higher threshold. Disk Specificity: While this alert monitors minimum provisioning size across all disks, you can investigate further to identify the specific disk nearing capacity. Notification Frequency: Balance responsiveness with alert fatigue by setting an appropriate notification frequency. Consider the criticality of the data stored on the disks when determining the frequency. Action: When triggered, this alert prompts immediate action to free up space or expand storage. This may involve transferring data to another disk, deleting unnecessary files, or resizing the affected disk.
