What is Alibaba Cloud NIS Network Reachability Analysis?
This Openclaw Skills integration leverages the Alibaba Cloud Network Intelligence Service (NIS) to provide a comprehensive suite for network diagnostics. It allows developers and cloud architects to perform forward and reverse path analysis to verify connectivity between various resources like ECS, VPN gateways, and public IPs. By synthesizing data from NIS and CloudMonitor, the skill identifies specific bottlenecks, such as restrictive security group rules or missing route table entries, without ever modifying your live infrastructure.
Built with a focus on safety and visibility, the skill operates in a strict read-only mode. It excels at transforming complex JSON network data into human-readable Mermaid topology diagrams and correlating connectivity status with real-time performance metrics like CPU utilization and packet loss. This makes it an essential tool for maintaining high availability in complex cloud environments.
Alibaba Cloud NIS Network Reachability Analysis Use Cases
- Troubleshooting unreachable network paths between ECS instances or hybrid cloud environments.
- Validating security group and route table configurations for new deployments.
- Visualizing complex network topologies using Mermaid diagrams for documentation or debugging.
- Monitoring resource health along a specific network path during connectivity drops.
- Performing bidirectional connectivity checks to ensure full duplex communication.
How Alibaba Cloud NIS Network Reachability Analysis Works
- The user initiates a diagnostic request by providing source and target resource details.
- The skill performs a Forward Path Analysis by calling the Alibaba Cloud NIS CreateAndAnalyzeNetworkPath API.
- It polls the analysis status until the task is finished and retrieves the reachability results.
- A Reverse Path Analysis is automatically triggered, simulating return traffic by swapping source/target and using ephemeral ports.
- The skill extracts path metadata and generates a Mermaid diagram to visualize the link between resources.
- For each resource in the path, it queries CloudMonitor for performance metrics (CPU, bandwidth, errors) from the last hour.
- Finally, it presents a consolidated report including reachability status, root cause error codes, and monitoring anomalies.
Alibaba Cloud NIS Network Reachability Analysis Setup
To use this within Openclaw Skills, ensure you have the Aliyun CLI installed (v3.3.1 or higher) and properly configured with the necessary RAM permissions.
# Verify CLI version
aliyun version
# Enable automatic plugin installation
aliyun configure set --auto-plugin-install true
# Check your authentication status (Do not input secrets here)
aliyun configure list --user-agent AlibabaCloud-Agent-Skills
Alibaba Cloud NIS Network Reachability Analysis Data Schema & Taxonomy
The skill organizes analysis data based on the path direction and resource types involved. Metadata is categorized as follows:
| Data Category | Description |
|---|---|
| Analysis ID | Unique identifier for forward and reverse tasks. |
| Path Results | Includes Reachable status (Boolean), error codes, and specific block points (Security Groups, Routes). |
| Topology Data | A list of nodes (nodeType, bizInsId) and links defining the network graph. |
| Metrics | Time-series monitoring data for ECS, EIP, NAT, CLB, and VBR resources. |
Alibaba Cloud NIS Network Reachability Analysis Advanced Features
- Automated bidirectional analysis (Mandatory forward/reverse check flow).
- Dynamic ephemeral port simulation (49152-65535) for realistic reverse traffic analysis.
- Real-time Mermaid diagram generation for instant network visualization.
- Cross-service correlation between NIS path analysis and CloudMonitor performance metrics.
- Multi-resource support covering ECS, VSwitch, Internet IP, VPN, VBR, and CLB.
