+# 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"
+```

+### Tags:
+
+- All measurements have the following tags:
+    - port
+    - server
+    - server_name

+  ## 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:
