Daemon run not outputing result to file for HTTP request per second display mode

[ooctavv]

Hello,

I have installed httpry-0.1.8-1.el7.x86_64.rpm on CentOS and i am running httpry in the following way:

sudo httpry -d -s -i eth0 'tcp dst port 3000' -o pry.txt

I want to have HTTP request per second display mode in that pry.txt output.

It creates the file with the following content:

[centos@nifi1-qa ~]$ cat pry
# httpry version 0.1.8
# Fields: host

but, unfortunately, no other output like:
"```
