Lightweight, web-based server monitoring.
The Python backend uses Flask and Tornado to serve JSON data thanks to psutil, while the frontend uses Smoothie Charts for the live graphs.
What does it look like?
Windows Server 2012 users
diskperf -y to enable disk activity monitoring. Without doing so,
psutil and lookout will fail to run properly. As a side effect, doing so allows
you to also view disk activity in Task Manager.
Running directly from source
To run Lookout from source, install Python 2.7, pip and a C compiler. Windows users should use MSVC++ 2008 (not even a newer version) for the least headaches.
Then install dependencies with
pip install -r requirements.txt.
lookout.py to start monitoring. You can optionally supply the
port to listen on as the first argument (e.g.
lookout.py 8080), but the
default is port 80.
Skype users, please note that ports 80 and 443 are taken by default; you will need to turn off "Use 80 and 443 for incoming connections" and restart Skype to use those ports.
If you're using Debian, Ubuntu or relatives, setup might look like this:
apt-get install git build-essential python python-dev python-pip git clone git://github.com/delan/lookout.git cd lookout pip install -r requirements.txt python lookout.py
How to build a standalone executable
Werkzeug does some crazy import magic that breaks PyInstaller's module
detection, so please edit werkzeug's
__init__.py and remove everything after
the line where
__version__ is defined.
Download PyInstaller and in this directory, run
path/to/pyinstaller.py -F lookout.spec.
The resulting executable will be found as
dist/lookout.exe. Run it to start
monitoring, again with an optional port argument.
