Example of graphite_param in documentation only sends 0 for me

[tareq-khandaker-ck-xx]

Hi,

I managed to get graphite_default_data and graphite_data working for me successfully (I can see line items being sent, and field values fluctuate based on request behaviour like as expected). When I try to set up custom parameter as shown in https://github.com/mailru/graphite-nginx-module#nginx-api-for-lua , I only see values of 0 being sent. I'm not using compiling in any additional modules into nginx besides this graphite-nginx-module and I don't see any errors in the logs, so I am really puzzled as to what might be wrong.

Thank you once again,

Show your nginx.conf, please And the output of nginx -V

I think the issue it seems that both our ngx-lua-module and nginx versions are above the given range.

From what I see ngx-lua is version 0.10.11 and nginx is 1.13.6.

Do you by chance know if support for those versions would be added soon? Or perhaps you have an alternative suggestion?

Also, to answer your question, the output of nginx -V is:

The relevant part of nginx.conf for graphite is:

graphite_config prefix=[service_name] server=telegraf;

And then I made an endpoint like so:

    location /test {
        graphite_param name=resty.control.pass aggregate=sum interval=1m;
        content_by_lua_block {
           ngx.graphite("resty.control.pass", 1)
           ngx.say('hello')
        }
    }

In the end I got 0's:

[service_name],host=59696c210caf,instance=187b741bc47d,location=control,module=resty pass=0 1534526769000000000

[kirimedia]

I fixed it Try version 2.3

[coding-brigadier]

It works! I am getting the right values now:

[service_name],host=59696c210caf,instance=a487e449dbe3,location=control,module=resty pass=1 1534876993000000000
