Alibabacloud Kvstore Health Inspection

HARD RULES (violation = immediate failure)

Core Rule: All inspections MUST be executed via python3 scripts/health-inspect.py. The script encapsulates all correct API calls internally. The AI MUST NOT call aliyun CLI directly to collect inspection data.

1. Do NOT call aliyun CLI to collect data: All inspection data must be obtained through health-inspect.py. The AI must not bypass the script by running aliyun r-kvstore directly. The only aliyun commands allowed for direct AI invocation are: aliyun configure list (check credentials), aliyun version (check version), aliyun configure set (set configuration), aliyun plugin (plugin management)
2. Do NOT use CloudMonitor (cms) APIs: Performance monitoring data is obtained by the script via R-kvstore describe-history-monitor-values API. NEVER use aliyun cms describe-metric-list/describe-metric-data as a substitute
3. Do NOT connect to Redis directly: Do not install redis-cli clients, do not connect to Redis instances in any way, do not execute any Redis commands
4. Do NOT perform write operations: Do not call modify-instance*, create-instance*, delete-instance* or any other APIs that modify instance state
5. Report errors on API failure: If the script fails at any step, mark it as "retrieval failed" in the report. Do NOT attempt to obtain data through alternative methods

AI Behavior Rules (MUST follow)

1. Must use the script for inspection: All inspection operations can only be done via python3 scripts/health-inspect.py. The AI's role is: identify user intent -> assemble correct script parameters -> execute script -> present report to user. Do NOT call aliyun CLI directly to collect any inspection data
2. Inspection mode selection: Choose the correct execution mode based on user intent
   • User says "all instances" / "full account" -> use --all
   • User specifies multiple instance IDs -> pass multiple IDs: health-inspect.py r-xxx r-yyy
   • User specifies a single instance -> single-instance mode: health-inspect.py r-xxx
3. Inspection item selection: Map user's focus areas to --item parameters
   • User mentions "CPU" / "memory" / "resource usage" / "connections" / "bandwidth" -> --item resource
   • User mentions "session" / "connection" / "active connections" / "client IPs" -> --item session
   • User mentions "big key" / "hot key" / "large key" / "memory usage by key" -> --item bigkey
   • User mentions "slow log" / "slow command" / "latency" -> --item slowlog
   • User mentions "alert" / "alarm" / "warning" / "notification" -> --item alert
   • User mentions multiple areas -> combine multiple --item (e.g., --item resource --item slowlog)
   • User does not specify (e.g., "run inspection" / "full check") -> do not add --item, default to full inspection
4. Unified output: Multi-instance (>=2) reports go to a single directory with an index page (index.html) + individual detail reports; single-instance outputs a single file
5. Do not manually list instances then run one by one: The script's --all has built-in instance discovery. The AI does not need to call describe-instances first
6. On script failure: If the script reports an error at any step, relay the error message to the user. Do NOT call aliyun CLI to try alternative data retrieval methods
7. Do NOT ask follow-up questions after report output: This skill is inspection-only. Once the report is generated, the task is complete. Do NOT append questions like "Need further analysis?" or any similar follow-up prompts

AI Execution Flow (follow this order strictly)

1. Identify user intent, select correct inspection mode and parameters
2. Execute python3 scripts/health-inspect.py <params> — one command completes all data collection
3. The script automatically handles: Region discovery, R-kvstore API calls for performance data, report generation
4. Present the generated report file path to the user
5. Answer follow-up questions based on report content

Alibaba Cloud Redis (KVStore) Instance Health Inspection Skill

This skill performs resource usage health inspection of Redis instances and generates standardized reports.

Inspection Dimensions (7 Sections):

1. Instance Basic Information — ID, name, version, class, architecture, status
2. Current Sessions — Connection usage distribution, node topology
3. Resource Usage (Last 7 Days) — CPU, Memory, Connection, Bandwidth with ECharts charts
4. Big Key / Hot Key — Cache analysis Top10 big keys and Top10 hot keys
5. Slow Log Statistics (Last 7 Days) — Slow command aggregation by type
6. Alert History (Last 7 Days) — CloudMonitor (CMS) alert records
7. Inspection Conclusions & Recommendations — Risk-prioritized suggestions

Resource Metrics:

• Input/Output Bandwidth Usage
• Proxy metrics (cluster/splitrw only)
• Persistent Memory Usage (Tair only)
• Disk Usage (Tair only)

Architecture Support:

• Standard (single-node, master-replica)
• Cluster (cluster edition)
• SplitRW (read-write splitting)

Instance Type Support:

• Redis Community Edition
• Tair (DRAM)
• Tair (Persistent Memory, InstanceClass: tair.scm.*)
• Tair (ESSD, InstanceClass: tair.essd.*)

Architecture: R-kvstore API (DescribeHistoryMonitorValues) + Aliyun CLI

Prerequisites

Runtime Environment:

• Python >= 3.7
• Aliyun CLI >= 3.3.3
• OS: Linux / macOS / Windows

Required CLI Tools:

• aliyun CLI >= 3.3.3 (with valid credentials configured)
• No redis-cli needed (this skill completes all inspection via API, no direct Redis connection required)

Python Dependencies:

# Uses only Python standard library: subprocess, json, os, sys, datetime
# All Alibaba Cloud API calls are made through aliyun CLI

Installation Verification:

Pre-check: Aliyun CLI >= 3.3.3 required Run aliyun version to verify >= 3.3.3. If not installed or version too low, see references/cli-installation-guide.md for detailed installation instructions, or run curl -fsSL https://aliyuncli.alicdn.com/setup.sh | bash to install/update. Then [MUST] run aliyun configure set --auto-plugin-install true to enable automatic plugin installation. Then [MUST] run aliyun plugin update to ensure plugins are up-to-date.

[MUST] CLI User-Agent — Every business API aliyun CLI invocation (e.g. aliyun r-kvstore …, aliyun das …, aliyun cms …) MUST carry the --user-agent flag with the full UA template defined in the Observability section below. System / utility commands MUST NOT carry --user-agent (see the exclusion list in the Observability section). Do NOT rely on the deprecated aliyun configure ai-mode mechanism or the ALIBABA_CLOUD_USER_AGENT environment variable — both have been retired.

Observability (MUST follow before any aliyun CLI invocation)

This skill emits observability headers via the --user-agent flag on every business API aliyun CLI command. The deprecated aliyun configure ai-mode enable / disable / set-user-agent commands and the ALIBABA_CLOUD_USER_AGENT env var MUST NOT be used.

Scope rule (SA-2.11):

• ✅ Business API commands (carry --user-agent): aliyun r-kvstore <action>, aliyun das <action>, aliyun cms <action>, etc.
• ❌ System / utility commands (MUST NOT carry --user-agent): aliyun configure … (e.g. aliyun configure list, aliyun configure set), aliyun plugin … (e.g. aliyun plugin update, aliyun plugin install, aliyun plugin list), aliyun help, aliyun version, aliyun upgrade, aliyun --help.

Step 1 — Generate a session ID (once per skill invocation)

# 32-char lowercase hex without dashes (UUID v4)
export ALICLOUD_SKILL_SESSION_ID="$(uuidgen | tr -d '-' | tr 'A-F' 'a-f')"

Step 2 — UA template (MUST use full format including session-id segment)

AlibabaCloud-Agent-Skills/alibabacloud-kvstore-health-inspection/${ALICLOUD_SKILL_SESSION_ID}

The /{session-id} segment is mandatory — a UA without it will be rejected by SA-2.11 review.

Step 3 — Pass --user-agent on every business API aliyun CLI command

Applies only to business product commands (r-kvstore / das / cms / etc.). System commands listed in the scope rule above MUST NOT have --user-agent appended.

# ✅ Business API command — UA REQUIRED
aliyun r-kvstore describe-instances \
  --user-agent "AlibabaCloud-Agent-Skills/alibabacloud-kvstore-health-inspection/${ALICLOUD_SKILL_SESSION_ID}"

# ❌ System / utility commands — UA MUST NOT be passed
aliyun configure list
aliyun plugin update
aliyun version

The Python script scripts/health-inspect.py automatically injects this UA on every internal business API aliyun invocation, and never on system commands. When the AI issues direct CLI calls, it MUST append --user-agent "AlibabaCloud-Agent-Skills/alibabacloud-kvstore-health-inspection/${ALICLOUD_SKILL_SESSION_ID}" to business API commands only — and MUST NOT append it to aliyun configure …, aliyun plugin …, aliyun help, aliyun version, aliyun upgrade, or aliyun --help.

Do not skip the UA, alter the format, or omit the /{session-id} segment.

Required RAM Permissions

This skill uses read-only APIs only. No write permissions are required.

For the full permission policy and detailed descriptions, see references/ram-policies.md.

[MUST] Permission Failure Handling: When any command or API call fails due to permission errors at any point during execution, follow this process:

1. Read references/ram-policies.md to get the full list of permissions required by this SKILL
2. Use ram-permission-diagnose skill to guide the user through requesting the necessary permissions
3. Pause and wait until the user confirms that the required permissions have been granted

Authentication

Pre-check: Alibaba Cloud Credentials Required

Security Rules:

• NEVER read, echo, or print AK/SK values
• NEVER ask the user to input AK/SK directly in the conversation or command line
• ONLY use aliyun configure list to check credential status

aliyun configure list

Check the output for a valid profile.

If no valid profile exists, STOP here. Guide the user to configure credentials outside of this session.

Core Workflow

Recommended: Use the Automated Script (one-command inspection)

python3 scripts/health-inspect.py <INSTANCE_ID> [options]

CLI Arguments:

Examples:

# Single instance (auto-discover Region)
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx

# Multi-instance
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx r-bp2yyyyyyyyyyyyyy

# All instances in account
python3 scripts/health-inspect.py --all

# All instances in specific Region
python3 scripts/health-inspect.py --all --region cn-hangzhou

# Custom time range (last 3 days)
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --days 3

# Resource usage only (CPU/memory/connection/bandwidth)
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --item resource

# Big key and hot key analysis only
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --item bigkey

# Slow logs only
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --item slowlog

# Slow logs and alerts only
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --item slowlog --item alert

# Batch + specific items
python3 scripts/health-inspect.py --all --item resource --item slowlog

# Markdown format
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --format markdown

# Custom output directory
python3 scripts/health-inspect.py --all -o /tmp/redis_report

# Full parameters
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx -p myprofile -r cn-hangzhou -d 14 -o ./report

The script completes all inspection steps automatically. For multi-instance runs, reports are output to a single directory with a summary page (index.html).

Item Selection Examples:

When the user specifies particular inspection items, map their intent to --item parameters:

# User says "check CPU and memory" -> resource item
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --item resource

# User says "analyze slow commands" -> slowlog item
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --item slowlog

# User says "find big keys" -> bigkey item
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --item bigkey

# User says "check sessions and connections" -> session item
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --item session

# User says "review alerts" -> alert item
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --item alert

# User specifies multiple items
python3 scripts/health-inspect.py r-bp1xxxxxxxxxxxx --item resource --item bigkey --item slowlog

When the user does not specify items, omit the --item parameter to run full inspection (all 7 sections).
