This is a graphical log viewer for Python's standard logging module. It can be targeted with a SocketHandler with no additional setup (see Usage).
The program is in beta: it's lacking some features and may be unstable, but it works. cutelog is cross-platform, although it's mainly written and optimized for Linux.
This is my first released project, so the code is by no means stellar. Feedback and contributions are appreciated!
- Allows any number of simultaneous connections
- Fully customizable look of log levels and columns
- Filtering based on level and name of the logger, as well as filtering by searching
- Search through all records or only through filtered ones
- View exception tracebacks or messages in a separate window
- Dark theme (with its own set of colors for levels)
- Pop tabs out of the window, merge records of multiple tabs into one
If you're using Linux, install PyQt5 from your package manager before installing cutelog (package name is probably python3-pyqt5
or python-pyqt5
). Or just run pip install pyqt5
to install it from pip, which is sub-optimal.
$ pip install --upgrade cutelog
Or install the latest development version from the source:
$ pip install git+https://github.com/busimus/cutelog.git
- Python 3.5 (or newer)
- PyQt5 (preferably 5.6 or newer)
- Start cutelog
- Put the following into your code:
import logging
from logging.handlers import SocketHandler
log = logging.getLogger('Root logger')
log.setLevel(1) # to send all messages to cutelog
socket_handler = SocketHandler('127.0.0.1', 19996) # default listening address
log.addHandler(socket_handler)
log.info('Hello world!')
Afterwards it's recommended to designate different loggers for different parts of your program with log_2 = log.getChild("Child logger"). This will create "log namespaces" which allow you to filter out messages from various subsystems of your program.
