uwsgitop exception

[Manas Gupta]

Hi,
I have uwsgi running a stats server as follows -
stats = /tmp/uwsgi-statsock

uwsgitop is started as - uwsgitop /tmp/uwsgi-statsock
It loads up just fine and I see the 4 uwsgi processes.

However when I access the app via the browser, uwsgitop exists with the following message.

easilydo_executor@ip-10-112-249-191:~$ uwsgitop /tmp/uwsgi-statsock
Traceback (most recent call last):

Platform/Environment

• OS: Ubuntu 12 (Precise)
• uwsgi, uwsgi-plugin-python installed via apt-get
  ii uwsgi 1.0.3+dfsg-1ubuntu0.1 fast, self-healing application container server
  ii uwsgi-core 1.0.3+dfsg-1ubuntu0.1 fast, self-healing application container server (core)
  ii uwsgi-plugin-python 1.0.3+dfsg-1ubuntu0.1 Python WSGI plugin for uWSGI
• uwsgitop installed via pip
• Running a Django app. Nginx is the frontend to uWSGI.

I re-ran uwsgi with stats on a network socket. Same problem - but slightly different error message
