# Apache Input Plugin
The Apache plugin collects server performance information using the [`mod_status`](https://httpd.apache.org/docs/2.4/mod/mod_status.html) module of the [Apache HTTP Server](https://httpd.apache.org/).
Typically, the `mod_status` module is configured to expose a page at the `/server-status?auto` location of the Apache server. The [ExtendedStatus](https://httpd.apache.org/docs/2.4/mod/core.html#extendedstatus) option must be enabled in order to collect all available fields. For information about how to configure your server reference the [module documentation](https://httpd.apache.org/docs/2.4/mod/mod_status.html#enable).
### Configuration:
```toml
# 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
```
