One further type of profiler that is available in Odoo generates a graph for the executed method. This profiler is available in the misc package, so you need to import it from there. It will generate a file with statistics data that will generate a graph file. To use this profiler, you need to pass the path of the file path as an argument. When this function is called, it will generate a file on the given location. Take a look at the following example, which generates the make_available.prof file on the desktop:

from odoo.tools.misc import profile
...
@profile('/Users/parth/Desktop/make_available.profile')
def make_available(self):
    if self.state != 'lost':
        self.write({'state': 'available'})
        self.env['res.partner'].create({'name': 'test', 'email': '[email protected]'})
    return True

When the make_available method is called, it will generate a file on the desktop. To convert this data into graph data, you will need to install the gprof2dot tool and then execute the given command to generate the graph:

gprof2dot -f pstats -o /Users/parth/Desktop/prof.xdot   /Users/parth/Desktop/make_available.prof

This command will generate the prof.xdot file on the desktop. Then, you can display the graph with xdot with the given command:

xdot /Users/parth/Desktop/prof.xdot

The preceding xdot command will generate the graph shown in the following screenshot:

Here, you can zoom in, check the call stack, and look at details of execution times for the methods.
