Yet another error while parsing line issue

[hedasp]

Environment

Ubuntu: 18.04
Nginx: 1.14.0
Prometheus_nginxlog_exporter: 1.9.2

issue

Parsing error, and no output:

# HELP nginx_parse_errors_total Total number of log file lines that could not be parsed
# TYPE nginx_parse_errors_total counter
nginx_parse_errors_total{fm="fm"} 436

Configurations:

nginx.conf:

       # Logging Settings
        ##
log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$request_time $status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for" "$ssl_protocol/$ssl_cipher"';

        access_log /var/log/nginx/access.log main;
        error_log /var/log/nginx/error.log;```

**exporter.hcl:**
´´´
listen {
  port = 4040
}

namespace "fm" {
  source_files = ["/var/log/nginx/access.log"]


  format = "$remote_addr - $remote_user [$time_local] \"$request\" $status $body_bytes_sent \"$http_referer\" \"$http_user_agent\" \"$http_x_forwarded_for\" \"$ssl_protocol/$ssl_cipher\""

  labels {
    app = "fm"
  }
  metrics_override = { prefix = "nginx"}
  namespace_label = "fm"
}
´´´

**example log output:**

From other servers(ubuntu 20.04, export versjon 1.8.0 though) the logs are read without issues.

What am I missing? Please help.🥺

Sorry for the late response. Looks like there is an additional value in your log file between "$request" and $status (log file says "GET /favicon.ico HTTP/1.1" 0.000 200 in that area.

Let me know if that helps.

There was indeed a missing value in hcl-conf. (For others as blind as me: $request_time)
Sorry for wasting your time, and thank you for always keeping a high standard in code and communication!
