The Agent Skills Directory

Diagnostic Command Execution: The skill incorporates standard system utilities such as jstack, jmap, top, and fuser to perform node health checks and heap analysis. These operations are essential for identifying OOM conditions and process stalls in database environments.
Network Connectivity Verification: Diagnostic steps include the use of curl and wget to verify reachability for external storage services like AWS S3 and HDFS. These checks are directed at well-known service endpoints or internal cluster APIs to troubleshoot data lake connectivity.
Log and Metadata Ingestion: The instructions guide the agent to analyze Apache Doris logs (fe.log, be.log) and audit records. While this involves processing external data, the activity is scoped to specific grep patterns and metric extraction required for performance tuning.
Resource Management Interface: The skill interacts with Linux cgroups and process limits to monitor and adjust resource isolation. This is standard practice for managing high-performance database workloads.
