|  | ============= | 
|  |  | 
|  | NAME | 
|  | ---- | 
|  | perf-trace - strace inspired tool | 
|  |  | 
|  | SYNOPSIS | 
|  | -------- | 
|  | [verse] | 
|  | 'perf trace' | 
|  |  | 
|  | DESCRIPTION | 
|  | ----------- | 
|  | This command will show the events associated with the target, initially | 
|  | syscalls, but other system events like pagefaults, task lifetime events, | 
|  | scheduling events, etc. | 
|  |  | 
|  | Initially this is a live mode only tool, but eventually will work with | 
|  | perf.data files like the other tools, allowing a detached 'record' from | 
|  | analysis phases. | 
|  |  | 
|  | OPTIONS | 
|  | ------- | 
|  |  | 
|  | --all-cpus:: | 
|  | System-wide collection from all CPUs. | 
|  |  | 
|  | -p:: | 
|  | --pid=:: | 
|  | Record events on existing process ID (comma separated list). | 
|  |  | 
|  | --tid=:: | 
|  | Record events on existing thread ID (comma separated list). | 
|  |  | 
|  | --uid=:: | 
|  | Record events in threads owned by uid. Name or number. | 
|  |  | 
|  | --no-inherit:: | 
|  | Child tasks do not inherit counters. | 
|  |  | 
|  | --mmap-pages=:: | 
|  | Number of mmap data pages. Must be a power of two. | 
|  |  | 
|  | --cpu:: | 
|  | Collect samples only on the list of CPUs provided. Multiple CPUs can be provided as a | 
|  | comma-separated list with no space: 0,1. Ranges of CPUs are specified with -: 0-2. | 
|  | In per-thread mode with inheritance mode on (default), Events are captured only when | 
|  | the thread executes on the designated CPUs. Default is to monitor all CPUs. | 
|  |  | 
|  | --duration: | 
|  | Show only events that had a duration greater than N.M ms. | 
|  |  | 
|  | --sched: | 
|  | Accrue thread runtime and provide a summary at the end of the session. |
