# Telegraf Plugin: nginx_plus
Nginx Plus is a commercial version of the open source web server Nginx. The use this plugin you will need a license. For more information about the differences between Nginx (F/OSS) and Nginx Plus, [click here](https://www.nginx.com/blog/whats-difference-nginx-foss-nginx-plus/).
Structures for Nginx Plus have been built based on history of
[status module documentation](http://nginx.org/en/docs/http/ngx_http_status_module.html)
### Configuration:
```
# Read Nginx Plus' advanced status information
[[inputs.nginx_plus]]
## An array of Nginx status URIs to gather stats.
urls = ["http://localhost/status"]
```
### Measurements & Fields:
- nginx_plus_processes
- respawned
- nginx_plus_connections
- accepted
- dropped
- active
- idle
- nginx_plus_ssl
- handshakes
- handshakes_failed
- session_reuses
- nginx_plus_requests
- total
- current
- nginx_plus_upstream, nginx_plus_stream_upstream
- keepalive
- zombies
- nginx_plus_upstream_peer, nginx_plus_stream_upstream_peer
- requests
- unavail
- healthchecks_checks
- header_time
- response_time
- state
- active
- downstart
- healthchecks_last_passed
- weight
- responses_1xx
- responses_2xx
- responses_3xx
- responses_4xx
- responses_5xx
- received
- selected
- healthchecks_fails
- healthchecks_unhealthy
- backup
- responses_total
- sent
- fails
- downtime
### Tags:
- nginx_plus_processes, nginx_plus_connections, nginx_plus_ssl, nginx_plus_requests
- server
- port
- nginx_plus_upstream, nginx_plus_stream_upstream
- upstream
- server
- port
- nginx_plus_upstream_peer, nginx_plus_stream_upstream_peer
- id
- upstream
- server
- port
- upstream_address
### Example Output:
Using this configuration:
```
[[inputs.nginx_plus]]
## An array of Nginx Plus status URIs to gather stats.
urls = ["http://localhost/status"]
```
When run with:
```
./telegraf -config telegraf.conf -input-filter nginx_plus -test
```
It produces:
```
