# Telegraf Plugin: Tengine
### Configuration:
```
# Read Tengine's basic status information (ngx_http_reqstat_module)
[[inputs.tengine]]
## An array of Tengine reqstat module URI to gather stats.
urls = ["http://127.0.0.1/us"]
## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification
# insecure_skip_verify = false
## HTTP response timeout (default: 5s)
response_timeout = "5s"
```
### Measurements & Fields:
- Measurement
- bytes_in total number of bytes received from client
- bytes_out total number of bytes sent to client
- conn_total total number of accepted connections
- req_total total number of processed requests
- http_2xx total number of 2xx requests
- http_3xx total number of 3xx requests
- http_4xx total number of 4xx requests
- http_5xx total number of 5xx requests
- http_other_status total number of other requests
- rt accumulation or rt
- ups_req total number of requests calling for upstream
- ups_rt accumulation or upstream rt
- ups_tries total number of times calling for upstream
- http_200 total number of 200 requests
- http_206 total number of 206 requests
- http_302 total number of 302 requests
- http_304 total number of 304 requests
- http_403 total number of 403 requests
- http_404 total number of 404 requests
- http_416 total number of 416 requests
- http_499 total number of 499 requests
- http_500 total number of 500 requests
- http_502 total number of 502 requests
- http_503 total number of 503 requests
- http_504 total number of 504 requests
- http_508 total number of 508 requests
- http_other_detail_status total number of requests of other status codes*http_ups_4xx total number of requests of upstream 4xx
- http_ups_5xx total number of requests of upstream 5xx
### Tags:
- All measurements have the following tags:
- port
- server
- server_name
### Example Output:
Using this configuration:
```
[[inputs.tengine]]
## An array of tengine req_status_show URI to gather stats.
urls = ["http://127.0.0.1/us"]
```
When run with:
```
./telegraf --config telegraf.conf --input-filter tengine --test
```
It produces:
```
