shmsnoop - Trace System V shared memory syscalls. Uses Linux eBPF/bcc.
shmsnoop [-h] [-T] [-p] [-t] [-d DURATION] [-n NAME]
shmsnoop traces System V shared memory syscalls: shmget, shmat, shmdt, shmctl
Since this uses BPF, only the root user can use this tool.
CONFIG_BPF and bcc.
- Trace all shm* syscalls:
- # shmsnoop
- Trace all shm* syscalls, and include timestamps:
- # shmsnoop -T
- Only trace shm* syscalls where the process contains "server":
- # shmsnoop -n server
This is from bcc.
Also look in the bcc distribution for a companion _examples.txt file containing example usage, output, and commentary for this tool.
Unstable - in development.
