ngxtop is not working at all

[manas86]

hi all,

As, I stated above ngxtop doesn't work other than ngxtop info.
can anyone have similar issue, if so then how did they solve it( i have python 2.7.5).
Or i'm doing something silly here?

sh-4.2$ ngxtop info
nginx configuration file:
/etc/nginx/nginx.conf
access log file:
/var/log/nginx/access.log
access log format:
$remote_addr - $remote_user [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent" "$http_x_forwarded_for"
available variables:
body_bytes_sent, http_referer, http_user_agent, http_x_forwarded_for, remote_addr, remote_user, request, status, time_local
sh-4.2$ ngxtop top remote_addr

I was getting roughly the same error when I was passing in a log that was completely empty.

This was because the offical Docker image I was using here, links /var/log/nginx/access.log to /dev/stdout, so when you do ngxtop -l /var/log/nginx/access.log, you are actually reading stdout, which is empty :)
