Alibaba Cloud EBS Disk Monitoring, Metric Analysis and Resource Overview

This skill enables you to:

1. Answer disk performance questions — how busy a disk is, whether it is hitting its IOPS/bandwidth ceiling, how it trends over time, and how it compares with other disks, instances, or availability zones (via aliyun ebs describe-metric-data).
2. Answer fleet composition questions — how many disks and how much capacity the account holds, how that splits across disk categories, regions, and billing types (both absolute and as percentages), and what disk events occurred (via aliyun ebs get-report / aliyun ebs list-reports, the same data set behind the EBS Lens Resource Overview console page).
3. Point users at the right dashboard — console URLs for CloudMonitor and CloudLens for EBS, optionally with a quick text summary so the user knows what to look at before clicking through.

Scenario Description

A. Disk Performance Metrics

Monitor and analyze cloud disk performance to track read/write IOPS and bandwidth (BPS), see how they trend over time, compare disks against each other, aggregate by disk type / instance / availability zone, and pinpoint bottlenecks and tuning opportunities.

B. Resource Overview Reports (CloudLens for EBS)

Retrieve aggregated resource reports covering: overall disk usage, disk count and capacity broken down by category (cloud_essd, cloud_essd_entry, cloud_auto, local_ssd_pro…), by region, and by billing (pay) type — each available as absolute values and as percentage shares — plus a disk event summary with event counts by event name and by region.

[MUST] Scope limit — do not over-promise. The 14 report cards this API returns are listed in references/related-commands.md · Report Card Titles. Encryption coverage, ESSD AutoPL adoption/burst usage, async replication pair count, dedicated block storage cluster count, and over-provisioned-disk detection are not among them. If the user asks for those, say the resource overview report does not expose them and point to the ECS console instead of inventing a figure.
