+# Apache Input Plugin
+
+This plugin collects performance information from [Apache HTTP Servers][apache]
+using the [`mod_status` module][mod_status_module]. Typically, this module is
+configured to expose a page at the `/server-status?auto` endpoint the server.
+
+The [ExtendedStatus option][extended_status] must be enabled in order to collect
+all available fields. For information about configuration of your server check
+the [module documentation][mod_status_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
+
+```toml @sample.conf
+# Read Apache status information (mod_status)
+[[inputs.apache]]
+  ## An array of URLs to gather from, must be directed at the machine
+  ## readable version of the mod_status page including the auto query string.
+  ## Default is "http://localhost/server-status?auto".
+  urls = ["http://localhost/server-status?auto"]
+
+  ## Credentials for basic HTTP authentication.
+  # username = "myuser"
+  # password = "mypassword"
+
+  ## Maximum time to receive response.
+  # 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
+```
