You should make sure http://localhost/status is the url where vts-module exposes its metrics.

I think this is the point you should take into account.

Yes, I can access http://localhost/status from my browser.

And this url should return json format metrics instead of html content.

Hi hnlq715,
Thanks for your help, I tried change nginx.conf and change the code "vhost_traffic_status_display_format html;" to "vhost_traffic_status_display_format json;" and now it's ok:
./nginx-vts-exporter &

But I have another questions, "nginx-vts-exporter" process will terminated automatically about in a day, do you konw how can I setup log and to find the root cause?

[sysulq]

Nice to hear that 😃
The log of nginx-vts-exporter would direcetly print into stdout, and you can use nohup ./nginx-vts-exporter & to capture log into nohup.out file.

I created log file for nginx-vts-exporter, but when the process terminated, no any other information:

tailf /var/log/nginx-vts-exporter.log

I don't know why the process terminted automatically, please advise.

[sysulq]

Maybe the process exits when your ssh terminal quits? Please try nohup ./nginx-vts-exporter & to launch this program

[smallfish01]

Yes, you are right, I used "nohup" and the process is running ok now.
Thanks you very much!

[sysulq]

Nice :-)

Scraping information from : http://localhost/status
How to replace it to more correct path like http://localhost/status/format/json ? I made
export NGINX_STATUS=http://localhost/status/format/json but unsuccessfully.
