| TRACE-CMD-STREAM(1) |
| =================== |
| |
| NAME |
| ---- |
| trace-cmd-stream - stream a trace to stdout as it is happening |
| |
| SYNOPSIS |
| -------- |
| *trace-cmd stream ['OPTIONS']* ['command'] |
| |
| DESCRIPTION |
| ----------- |
| The trace-cmd(1) stream will start tracing just like trace-cmd-record(1), except |
| it will not record to a file and instead it will read the binary buffer |
| as it is happening, convert it to a human readable format and write it to |
| stdout. |
| |
| This is basically the same as trace-cmd-start(1) and then doing a trace-cmd-show(1) |
| with the *-p* option. trace-cmd-stream is not as efficient as reading from the |
| pipe file as most of the stream work is done in userspace. This is useful if |
| it is needed to do the work mostly in userspace instead of the kernel, and stream |
| also helps to debug trace-cmd-profile(1) which uses the stream code to perform |
| the live data analysis for the profile. |
| |
| |
| OPTIONS |
| ------- |
| These are the same as trace-cmd-record(1), except that it does not take |
| the *-o* option. |
