NGINX logs enrichment whether Dynatrace is enabled or not

[ahmad]

Hello all,

I've been following the article to enable Nginx logs enrichment and to include the DT in the Nginx logs however, I have Dynatrace implemented in one environment and it works fine but when I try to run Nginx on my local machine I get the following error:

[emerg] 1#1: unknown "dt_trace_id" variable
nginx: [emerg] unknown "dt_trace_id" variable

My config looks like this:

worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /tmp/nginx.pid;


events {
    worker_connections  1024;
}

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

    log_format  custom '$remote_addr - $remote_user [$time_local] "$request" '
                        '$status $body_bytes_sent "$http_referer" '
                        '[!dt dt.trace_id=$dt_trace_id,dt.span_id=$dt_span_id,dt.trace_sampled=$dt_trace_sampled] '
                        '"$http_user_agent" "$http_x_forwarded_for"';
    access_log  /var/log/nginx/access.log  custom;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

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

Anyone can advise on how I can do Nginx logs enrichment that can work whether Dynatrace is enabled or not?

Thank you.

@ahmad were you able to solve this issue or are you still experiencing it? If it was solved, what was the underlying problem?

Is nginx instrumented locally? What version of nginx is being run? Do you have the oneagent installed?

Nginx logs enrichment that can work whether Dynatrace is enabled or not? -- using this method depends on the nginx process being instrumented by the OneAgent
