Apache Input Plugin

The Apache plugin collects server performance information using the mod_status module of the Apache HTTP Server.

Typically, the mod_status module is configured to expose a page at the /server-status?auto location of the Apache server. The ExtendedStatus option must be enabled in order to collect all available fields. For information about how to configure your server reference the module documentation.

Configuration:

# 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
