Description

Hi I am getting below error while running bcc tool inside container for a process running inside container. perf_event_open(/sys/kernel/debug/tracing/events/uprobes/p__proc_32829_root_opt_java_openjdk_lib_server_libjvm_so_0xd45575_bcc_35680/id): Invalid argument

raise Exception("Failed to attach BPF to uprobe")
Exception: Failed to attach BPF to probe. it refers correct libjvm.so path inside container (/proc/32829/root/opt/java/../server/libjvm.so) . any suggestion how to fix this issue ?

Research direction

Start with /usr/share/bcc/tools/lib/ustat at _attach_probes and bcc/__init__.py at attach_uprobe, using the provided traceback as the entry point. Reproduce the failure for the containerized Java process and determine why perf_event_open rejects the reported libjvm.so uprobe path. Done means documenting a confirmed cause and a validated fix or limitation.
