# Telegraf Plugin: Tengine # Tengine Input Plugin
The tengine plugin gathers metrics from the
[Tengine Web Server](http://tengine.taobao.org/) via the
[reqstat](http://tengine.taobao.org/document/http_reqstat.html) module.
### Configuration: ### Configuration:
``` ```toml
# Read Tengine's basic status information (ngx_http_reqstat_module) # Read Tengine's basic status information (ngx_http_reqstat_module)
[[inputs.tengine]] [[inputs.tengine]]
## An array of Tengine reqstat module URI to gather stats. ## An array of Tengine reqstat module URI to gather stats.
urls = ["http://127.0.0.1/us"] urls = ["http://127.0.0.1/us"]
## HTTP response timeout (default: 5s)
# response_timeout = "5s"
## Optional TLS Config ## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem" # tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem" # tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem" # tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification ## Use TLS but skip chain & host verification
# insecure_skip_verify = false # insecure_skip_verify = false
## HTTP response timeout (default: 5s)
response_timeout = "5s"
``` ```
