I am trying to use nginx-sflow module with Ganglia-3.4.0 I cannot get it to 
work. 

Looking at ganglia code it looks like it expects HID to be passed to it. 
However, the nginx-sflow module never passes that. 

Compiled new 0.9.4 version and no more segfaults, etc. Which is great.

BUT:

- i am only getting COUNTERSSAMPLE but i am missing FLOWSAMPLE.

How do i activate nginx to send FLOWSAMPLE, cant figure it out...

Compiled with nginx 1.0.2.

First if you dont have default configfile on filesystem, you are getting this 
error message from every http request:

[error] 3711#0: *1 stat(/etc/hsflowd.auto) failed while logging request

If you make 0 byte /etc/hsflowd.auto, nginx will segault on every http request

Then if trying with example configuration i am getting error:
[error] 3935#0: *2755 line=rev_start tokc=^@rev_start while logging request

So it seems sflow module (0.9.3) does not work atm. 

What steps will reproduce the problem?
1. set up centOS 7 minimal on hyper-v environment
2. make install nginx with the mod and dependencies
3. rpm install sflowtool

What is the expected output?
0:0 < counterBlock_tag < 0:5 or 0:1000 < counterBlock_tag < 0:1013

What do you see instead?
1012 < counterBlock_tag

What version of the product are you using? On what operating system?
latest as of Jan 7th 2015 on centOS 7 minimal (upgraded to latest as of Jan 7th 
2015

Please provide any additional information below.

What steps will reproduce the problem?
1. Run an sflow-enabled nginx without an existing, valid /etc/hsflowd.auto
2. Lots of noise to error logs


What is the expected output? What do you see instead?
Less noise :)


What version of the product are you using? On what operating system?
0.9.4 with nginx 1.1.0 and 1.1.1

Please provide any additional information below.
I run a lot of different types of servers with the same nginx build. It's 
really easy to generate a mountain of log entries to nginx error log on boxes 
that don't expect to be running sflow and /etc/hsflowd.auto doesn't exist (and 
if it does exist but is empty, I get piles of errors like "syntax error : 
agentIP=<IP address>|<IPv6 address> (on line 0) while logging request...").

I think it would be less surprising to default to 'sflow off;' and have it 
activated with 'sflow on;', rather than defaulting to on. Or alternatively, if 
/etc/hsflowd.auto exists but is empty, then disable sflow logging.

Love the module btw!

What steps will reproduce the problem?
1. "nginx -s quit" will put worker into "shutting down" state which never 
finishes
2. "nginx -s stop" stops nginx successfully


What is the expected output? What do you see instead?

I would expect nginx workers shut down. Instead they hang in "shutting down" 
status

What version of the product are you using? On what operating system?

0.9.7, Centos 6
