Analyzer gen-core-dump

Name

gen-core-dump - Generate the core dump file via gcore

This analyzer generates a core dump file of a running process using the gcore utility to preserve the fault scene before process restart. It captures a complete snapshot of the process’s memory state, including all loaded libraries, stack frames, heap data, and register states. The generated core dump enables post-mortem analysis of critical issues such as CPU 100% utilization, memory leaks, or abnormal process behaviors without interrupting the running application. This is essential for troubleshooting production incidents where immediate process restart is required but forensic evidence must be preserved for root cause analysis.
