Nginx_status stub and backend question

Troubleshooting

My issue:
TCP expect network error: cannot connect to [[localhost]:5555]: [111] Connection refused

How I encountered the problem:
I am trying to monitor nginx_status stub using zabbix. After much investigation, I created a seperate nginx_status.conf file and placed it into the /etc/nginx/conf.d/nginx_status.conf

If I run curl the following
curl http://localhost:5555/nginx_status

I get a status report. shown below.
Active connections: 1
server accepts handled requests
1452 1452 1439
Reading: 0 Writing: 1 Waiting: 0

but … zabbix is reporting an error that the nginx service is down.
Below is an extract from the zabbix_agentd.log file.

Requested [net.tcp.service[http,“localhost”,“5555”]]
TCP expect network error: cannot connect to [[localhost]:5555]: [111] Connection refused
Sending back [0]

Solutions I’ve tried:
I have tried to place the status stub within the site config file and then it does not work at all. I don’t understand why I am getting a connection refused with status stub when it works on the commandline with curl.

I have read that this might be caused by a backend config missing, but I do not understand this at all.

My config:
/etc/nginx/conf.d/nginx_status.conf

server {
listen 127.0.0.1:5555;
server_name 127.0.0.1;
location = /nginx_status {
stub_status on;
access_log on;
allow 127.0.0.1;
# only allow access from 192.168.1.5 #
allow 192.168.1.31; # Zabbix server access
deny all;
}
}

Hope someone can advise me.
Thanks

I have now managed to resolve this issue.
It had nothing to do with nginx config.
All I had to do was modify the zabbix config to resolve the issue.

Please let me know if you would like to what was done.

Thanks
