Huawei Cloud MRS Alarm Diagnosis Skill

Overview

This skill diagnoses Huawei Cloud MRS (MapReduce Service) cluster alarms. Given alarm information (alarm ID, alarm name, occurrence time, cluster ID, node, related service/role), it locates the root cause and outputs repair steps and a verification method.

Architecture: Caller (Agent) → lakewatch_api_client.py (Python, scripts/) → LakeWatch API → MRS cluster (node resource data, logs, MRS Manager proxy); per-alarm knowledge base (alarms/<alarm_id>.md) drives the diagnosis flow.

Note on language: This SKILL.md, the documents under references/, and the per-alarm knowledge base under alarms/ are all written in English per the repository spec. Commands and code blocks are English throughout.

Applicable Scenarios:

• An MRS cluster raises an alarm and the root cause must be located
• An on-call engineer needs guided, per-alarm diagnostic steps
• Alarm triage where an alarm ID is provided
