Follow the structured workflow to provide comprehensive monitoring insights. ## 1. Overview ### Functional Overview Huawei Cloud ECS monitoring skill uses Cloud Eye Service (CES) to provide comprehensive monitoring and metric query capabilities for Elastic Cloud Server instances. Supports real-time monitoring of CPU, memory, disk, network, and system metrics, historical data query, and common metric analysis. ### Architecture Diagram ``` User Request → Huawei Cloud CLI (hcloud) → Cloud Eye Service (CES) → ECS Instance ↓ IAM Permission Verification ↓ Monitoring Data Return ``` ### Application Scenarios - Monitor ECS instance CPU, memory, disk, and network utilization - Query historical metrics for performance analysis - Set up basic monitoring dashboards - Troubleshoot performance bottlenecks - Analyze resource usage trends - Check system and custom metrics ### User Scenario Examples 1. **Basic monitoring request**: "Check my ECS instance performance" 2. **Specific metric query**: "Show CPU and memory usage for instance ecs-server-01" 3. **Historical data analysis**: "Show disk IO trends for the last 7 days" 4. **Troubleshooting**: "My ECS instance is slow, check all metrics" ## 2. Prerequisites ### CLI Installation and Verification Before starting any operations, you must install and verify Huawei Cloud CLI (hcloud): **Verify Installation:** ```bash hcloud --version ``` **If not installed, follow the detailed installation guide:** See `references/cli-installation-guide.md` for complete installation instructions for: - macOS - Linux - Windows ### Configuration Method Configure Huawei Cloud credentials: ```bash hcloud configure init ``` Follow the interactive prompts to set: - Access Key ID - Secret Access Key - Region - Project ID (optional) ### Security Rules **[MUST]** At the start of the Core Workflow (before any CLI invocation): ```bash hcloud configure list ``` **Security Rules:** - **NEVER** read, echo, or print AK/SK values (e.g., `echo $HUAWEICLOUD_ACCESS_KEY` is FORBIDDEN) - **NEVER** ask the user to input AK/SK directly in the conversation or command line - **ONLY** use `hcloud configure list` to check credential status **If no valid configuration exists, STOP here:** 1. Obtain credentials from [Huawei Cloud Console](https://console.huaweicloud.com/iam/#/mine/accessKey) 2. Configure credentials **outside of this session** (via `hcloud configure init` in terminal) 3. Return and re-run after `hcloud configure list` shows valid configuration ### IAM Permission Requirements This skill requires the following minimum IAM permissions: - `ecs:cloudServers:list` - List ECS instances - `ecs:cloudServers:get` - Get ECS instance details - `ces:metrics:list` - List available metrics - `ces:metricData:get` - Get metric data Additional optional permissions (e.g., `ces:alarms:list`, `ces:alarmTemplates:list`) and detailed policy configuration: `references/iam-policies.md` ### Permission Failure Handling When any operation encounters a permission error (e.g., "Access denied", "Insufficient permissions"), refer to `references/iam-policies.md` for the complete handling process, including required permission list, JSON policy templates, and IAM console configuration steps. ## 3. KooCLI Command Format Standards **[MUST]** Before executing any CLI command, read `references/related-commands.md` for command format standards. **Key Rules:** - Use proper command structure: `hcloud ` - Always specify region: `--cli-region=` - For ECS commands: use `ecs` service - For CES commands: use `ces` service - Use proper JSON formatting for complex parameters **[MUST] Command Format** - Every `hcloud` CLI command should follow Huawei Cloud CLI standards. ## 4. Core Workflow/Process ### Step 1: List Available ECS Instances First, list all ECS instances in the current region to help users identify the target instance. ```bash hcloud ECS NovaListServers --cli-region= --limit=50 ``` ### Step 2: Query Common Monitoring Metrics Based on user requirements, query relevant monitoring metrics. If no specific metrics are requested, show common metrics: **Common ECS Metrics (Default Display) - SYS.ECS Namespace:** 1. **CPU Utilization** (`cpu_util`) 2. **Memory Utilization** (`mem_util`) 3. **Disk Read/Write Rate** (`disk_read_bytes_rate`, `disk_write_bytes_rate`) 4. **Network In/Out Rate** (`network_incoming_bytes_rate_inband`, `network_outgoing_bytes_rate_inband`) 5. **Disk Utilization** (`disk_util_inband`) > **Note**: The above are SYS.ECS (base monitoring) metrics available without an agent. > For OS-level monitoring (AGT.ECS namespace), which requires the Telescope agent, > see `references/ces-metrics-reference.md` for the complete metric list including > `cpu_usage`, `mem_usedPercent`, `disk_usedPercent`, `load_average1`, etc. > Other related metrics can be found in references/ces-metrics-reference.md. **Namespace Selection and Fallback Strategy:** When querying ECS metrics, follow this namespace selection logic: 1. **Default**: Query SYS.ECS metrics first (no agent required, available for all instances) 2. **Fallback to AGT.ECS**: If any individual SYS.ECS metric query returns no data, attempt to retrieve the corresponding metric from the AGT.ECS namespace (e.g., `cpu_util` → `cpu_usage`). See `references/ces-metrics-reference.md` for the complete fallback mapping table. 3. **AGT.ECS only metrics**: Some metrics only exist in AGT.ECS namespace (e.g., `load_average1`, `net_tcp_total`, `disk_readTime`, `disk_inodesUsedPercent`). Query these directly with `--metrics.N.namespace="AGT.ECS"` and `--period=60`. **Common reasons for SYS.ECS metrics returning no data:** - The instance image does not have UVP VMTools installed (affects `mem_util`, `disk_util_inband`, `network_*_inband`) - The instance was recently created and metrics have not yet been generated (wait 5-10 minutes) - The instance is not in ACTIVE state **Command example - SYS.ECS query:** ```bash hcloud CES BatchListMetricData \ --metrics.1.namespace="SYS.ECS" \ --metrics.1.metric_name="cpu_util" \ --metrics.1.dimensions.1.name="instance_id" \ --metrics.1.dimensions.1.value="" \ --from=$(date -d '-1 hour' +%s)000 \ --to=$(date +%s)000 \ --period=300 \ --filter="average" \ --cli-region= ``` **Command example - AGT.ECS query (when SYS.ECS has no data, or for AGT.ECS-only metrics):** ```bash hcloud CES BatchListMetricData \ --metrics.1.namespace="AGT.ECS" \ --metrics.1.metric_name="cpu_usage" \ --metrics.1.dimensions.1.name="instance_id" \ --metrics.1.dimensions.1.value="" \ --from=$(date -d '-1 hour' +%s)000 \ --to=$(date +%s)000 \ --period=60 \ --filter="average" \ --cli-region= ``` > Other relevant commands are documented in references/related-commands.md. ### Step 3: Analyze and Compare Metrics Based on the monitoring data returned: - Compare current values against recommended thresholds - Identify metrics approaching or exceeding thresholds - For AGT.ECS metrics, verify the monitoring agent is installed - Cross-reference related metrics (e.g., CPU usage with load average) - **[MUST] Handle empty data**: If SYS.ECS metric query returns no data points: 1. Check if the instance is in ACTIVE state 2. Try the corresponding AGT.ECS metric (see fallback mapping in Step 2) 3. If AGT.ECS also returns no data, check if the Telescope agent is installed 4. Inform the user about possible reasons (UVP VMTools missing, instance too new, agent not installed) ### Step 4: Format and Present Results Present monitoring data in a clear, actionable format: - Show metric values with timestamps - Identify trends and anomalies - Provide recommendations if thresholds are exceeded - Suggest next steps for optimization ### Optional Path: Alarm Management If users need to view or manage alarms: ```bash # List alarms hcloud CES ListAlarms --cli-region= # List alarm templates hcloud CES ListAlarmTemplates --cli-region= ``` ## 5.

Output Format ### Monitoring Report Format ``` ## ECS Monitoring Report **Instance**: () **Region**: **Time Range**: to ### Key Metrics Summary - CPU Utilization: XX.XX% (avg), XX.XX% (max), XX.XX% (min) - Memory Utilization: XX.XX% (avg), XX.XX% (max), XX.XX% (min) - Disk Read Rate: XX.XX MB/s (avg) - Disk Write Rate: XX.XX MB/s (avg) - Network Inbound: XX.XX Mbps (avg) - Network Outbound: XX.XX Mbps (avg) ### Detailed Metrics | Time | CPU Usage | Memory Usage | Disk Read | Disk Write | Network In | Network Out | |------|-----------|--------------|-----------|------------|------------|-------------| | ... | ... | ... | ... | ... | ... | ... | ### Recommendations 1. [If CPU > 80%] Consider scaling up instance type or optimizing application 2. [If Memory > 85%] Consider adding memory or optimizing memory usage 3. [If Disk > 90%] Consider expanding disk or cleaning up files 4. [Network bottlenecks] Consider optimizing network configuration ``` ## 8. Verification Method Skill verification and testing methods: `references/verification-method.md` ### Basic Verification Steps 1. **Environment verification**: Ensure Huawei Cloud CLI is installed and configured 2. **Permission verification**: Verify IAM permissions are sufficient 3. **Function verification**: Test core monitoring functionality 4. **Error handling verification**: Test handling of various error scenarios ### Test Cases - Normal scenario: Successfully query monitoring data - Insufficient permissions scenario: Handle permission errors - Instance not found scenario: Handle instance lookup failures - Network error scenario: Handle connection issues ## 9. Best Practices Please refer to `references/best-practices.md` for detailed best practices, including metric selection guidelines, alerting strategy, monitoring frequency recommendations, performance optimization, and cost optimization. ### Core Principles 1. **Default to common metrics** - When user doesn't specify, default to showing common metrics 2. **Provide actionable insights** - Not just raw data, provide analysis and recommendations 3. **Batch query related metrics** - Reduce API call frequency by querying multiple metrics in a single request ## 10.
