django-profiler 1.1.1

Requirements

• python 2.7+

Installation

Install via pip or copy this module into your project or into your PYTHON_PATH.

Configuration

django settings.py constants

PROFILING_LOGGER_NAME
PROFILING_SQL_QUERIES

It is possible to change default django-profiler logger name by defining PROFILING_LOGGER_NAME = ‘logger_name’ in your django settings.py.

To log also sql queries into profiler logger set PROFILING_SQL_QUERIES to True in your django settings.py module.

Examples

Example 1

Using context manager approach. Output will be logged to profiling logger.

from profiling import Profiler
with Profiler('Complex Computation'):
    # code with some complex computations

Example 2

Using context manager approach. Output will be logged to profiling.Computation logger.

from profiling import Profiler
with Profiler('Computation'):
    # code with some complex computations

Example 3

Using standard approach. Output will be logged to profiling logger.

from profiling import Profiler
profiler =  Profiler('Complex Computation')
profiler.start()
# code with some complex computations
profiler.stop()

Example 4

Using standard approach and starting directly in constructor. Output will be logged to profiling logger.

from profiling import Profiler
profiler =  Profiler('Complex Computation', start=True)
# code with some complex computations
profiler.stop()

Example 5

Using decorator approach. Output will be logged to profiling.complex_computations logger.

from profiling import profile

@profile
def complex_computations():
    #some complex computations

Example 6

Using decorator approach. Output will be logged to profiling.ComplexClass.complex_computations logger.

from profiling import profile

class ComplexClass(object):
    @profile
    def complex_computations():
        #some complex computations

Example 7

Using decorator approach. Output will be logged to profiling.complex_computations logger. profile execution stats are logged to profiling.complex_computations logger.

from profiling import profile

@profile(stats=True)
def complex_computations():
    #some complex computations

Example 8

Using decorator approach. Output will be logged to profiling.complex_computations logger. profile execution stats are printed to sys.stdout.

import sys

from profiling import profile

@profile(stats=True, stats_buffer=sys.stdout)
def complex_computations():
    #some complex computations

Example 9

Using decorator approach. Output will be logged to profiling.ComplexClass.complex_computations logger. profile stats will be logged to profiling.ComplexClass.complex_computations.

from profiling import profile

class ComplexClass(object)
   @profile(stats=True)
   def complex_computations():
       #some complex computations
