Invalid duration time in Jaeger

[narayanasamyr]

Hi,

I am trying to integrate nginx with jaeger, but in jaeger UI am getting long duration time for a nginx request.
When i hit / on my nginx server it takes less than a second to load, but in jaeger its showing 18+ seconds.

I have made a small fix in opentracing_request_instrumentor.cpp and after that its working as expected.
what i changed:
replaced the
"auto timepoint = ngx_timeofday()
auto finish_timestamp =opentracing::convert_time_pointstd::chrono::steady_clock(to_system_timestamp(timepoint->sec, timepoint->msec)); " to

auto finish_timestamp = std::chrono::steady_clock::now();

My env details:

1. Jaeger: all jaeger components running in single container
   docker run -d -e COLLECTOR_ZIPKIN_HTTP_PORT=9411 -p5775:5775/udp -p6831:6831/udp -p6832:6832/udp -p5778:5778 -p16686:16686 -p14268:14268 -p9411:9411 jaegertracing/all-in-one:latest

2. Nginx - Used the docker image which described in this project
   rnburn/nginx-opentracing:latest

3. My nginx conf file

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

load_module modules/ngx_http_opentracing_module.so;
load_module modules/ngx_http_jaeger_module.so;

events {
worker_connections 1024;
}

http {

jaeger_service_name nginx-opentracing-test-service;

opentracing on;

jaeger_sampler_type const;

jaeger_sampler_param 1;

jaeger_reporter_log_spans on;

jaeger_reporter_local_agent_host_port 10.112.81.82:6831;

include       /etc/nginx/mime.types;
default_type  application/octet-stream;

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

access_log  /var/log/nginx/access.log  main;

sendfile        on;
#tcp_nopush     on;

keepalive_timeout  65;

#gzip  on;

include /etc/nginx/conf.d/*.conf;

}
