# syscalldist
**syscalldist** is the tool to profile syscalls.
## Build and run
```bash
# git clone https://github.com/Asphaltt/syscalldist.git
# cd syscalldist
# go generate && go build
# ./syscalldist -h
Usage of ./syscalldist:
--kernel-btf string kernel BTF file
-l, --list-syscall list syscalls of amd64 Linux used by Go syscall
--pid uint32 filter pid
--syscall uint32 filter syscall id
--syscall-name string filter syscall name
pflag: help requested

Histogram for syscall(0/read) (sum 1):
usecs : count distribution

2 -> 3 : 0 | |
4 -> 7 : 0 | |
8 -> 15 : 1 |****************************************|
Histogram for syscall(1/write) (sum 2):
usecs : count distribution
0 -> 1 : 0 | |
2 -> 3 : 0 | |
4 -> 7 : 2 |****************************************|
Histogram for syscall(9/mmap) (sum 1):
usecs : count distribution
0 -> 1 : 0 | |

```
## Raw tracepoints
`syscalldist` runs on raw tracepoints `sys_enter` and `sys_exit`.
