gprofng - The next generation GNU application profiling tool
gprofng [option(s)] action [qualifier] [option(s)] target [options]
This is the driver for the gprofng tools suite to gather and analyze performance data.
The driver executes the action specified. An example of an action is collect to collect performance data. Depending on the action, a qualifier may be needed to further define the command. The last item is the target that the command applies to.
There are three places where options are supported. The driver supports options. These can be found below. The action, possibly in combination with the qualifier also supports options. A description of these can be found in the man page for the command. Any options needed to execute the target command should follow the target name.
For example, to collect performance data for an application called a.out and store the results in experiment directory mydata.er, the following command may be used:
$ gprofng collect app -o mydata.er a.out -t 2
In this example, the action is collect, the qualifier is app, the single argument to the command is "-o mydata.er" and the target is a.out. The target command is invoked with the -t 2 option.
If gprofng is executed without any additional option, action, or target, a usage overview is printed.
The following environment variables are supported:
When building and installing from the source, the user can set the path to this configuration file to a non-default location. If this is the case, the user may set the "GPROFNG_SYSCONFDIR" environment variable to point to this location.
Otherwise, the gp-display-text, gp-display-src, and gp-archive tools cannot find this file.
The gprofng driver supports the following commands.
Collect performance data:
Display the performance results:
Miscellaneous commands:
It is also possible to invoke the lower level commands directly, but since these are subject to change, in particular the options, we recommend to use the driver.
gp-archive(1), gp-collect-app(1), gp-display-gui(1), gp-display-html(1), gp-display-src(1), gp-display-text(1)
Each gprofng command also supports the --help option. This lists the options and a short description for each option.
For example this displays the options supported on the gprofng collect app command:
$ gprofng collect app --help
The user guide for gprofng is maintained as a Texinfo manual. If the info and gprofng programs are correctly installed, the command info gprofng should give access to this document.
