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.
