|
- Start tracing a specific process by its PID:
|
2015-03-21 00:01:05 +00:00
|
|
|
|
|
|
|
|
`strace -p {{pid}}`
|
|
|
|
|
|
2016-01-07 17:31:27 +00:00
|
|
|
- Trace a process and filter output by system call:
|
2015-03-21 00:01:05 +00:00
|
|
|
|
2018-10-29 11:14:25 +00:00
|
|
|
`strace -p {{pid}} -e {{system_call_name}}`
|
2015-03-21 00:01:05 +00:00
|
|
|
|
2016-01-07 17:31:27 +00:00
|
|
|
- Count time, calls, and errors for each system call and report a summary on program exit:
|
2015-03-21 00:01:05 +00:00
|
|
|
|
2015-03-21 01:02:35 +00:00
|
|
|
`strace -p {{pid}} -c`
|
2016-01-03 18:17:07 +00:00
|
|
|
|
2016-01-07 17:31:27 +00:00
|
|
|
- Show the time spent in every system call:
|
2016-01-03 18:17:07 +00:00
|
|
|
|
|
|
|
|
`strace -p {{pid}} -T`

|
|

|
|
|
- Start tracing a program by executing it:
|
2016-08-22 12:59:39 +01:00
|
|
|
|
|
|
|
|
`strace {{program}}`
|
2017-12-07 19:16:57 +00:00
|
|
|
|
|
|
|
|
- Start tracing file operations of a program:
|
|
|
|
|
|
|
|
|
|
`strace -e trace=file {{program}}`
|
