Neither the png nor svg versions line up correctly the text and coloured boxes with each other. This may be a local rendering issue. At least the svg version has a proper white background (my png renders with a very dark grey background, making it very hard to make out some of the text). However, the svg version is unusable because none of the text is text: everything is svg:path with opaque d attributes (this may explain the alignment problems).<br>
<br>
Here are improved (more accurate) expressions for the various command syntaxes:<br>
<br>
$ lttng create [NAME] [--ctrl-url URL --data-url URL | --output PATH | --set-url URL | --no-output] [--snapshot]<br>
(the ctrl-url etc. options are in pre-emption order)<br>
<br>
$ lttng enable-channel (-k | -u) [--session NAME] NAME[,NAME2,...] [--discard | --overwrite] [--subbuf-size SIZE] [--num-subbuf NUM] [--switch-timer USEC] [--read-timer USEC] \<br>
[--output (mmap | splice)] [--buffers-uid | --buffers-pid | --buffers-global] [--tracefile-size SIZE [--tracefile-count COUNT]]<br>
<br>
$ lttng enable-event (-k | -u) [--session NAME] [--channel NAME] (--all [--tracepoint | --syscall] | \<br>
NAME[,NAME2,...] [--tracepoint [(--loglevel | --loglevel-only) LOGLEVEL] [--filter 'EXPRESSION'] | (--probe | --function) (addr | symbol | symbol+offset)])<br>
<br>
$ lttng add-context (-k | -u) [--session NAME] [--channel NAME] (--type TYPE)+<br>
<br>
$ lttng list (-k | -u)<br>
(not the full syntax, but rather the syntax that will get just a list of event names)<br>
<br>
$ lttng add-context --help<br>
(the only one that doesn't change!)<br>
<br>
Change "Kernelspace specific" into "Kernel specific".<br>
<br>
Add footnotes:<br>
* --session NAME defaults to the current session<br>
* --channel NAME in the enable-event case defaults to 'channel0', but only if the domain is virgin<br>
* --channel NAME in the add-context case defaults to all channels<br>
