# 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.

## Global configuration options <!-- @/docs/includes/plugin_config.md -->

In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.

[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins

## Configuration

```toml @sample.conf
# 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"]

  ## HTTP response timeout (default: 5s)
  # response_timeout = "5s"

  ## 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
```
