[APM/Elastic] Install APM Elastic inside container WordPress.

Hôm qua mình mới khám phá thêm thanh niên khá hay ho. Đó là APM trong họ hàng nhà Elastic
Elastic APM is an application performance monitoring system built on the Elastic Stack. It allows you to monitor software services and applications in real-time, by collecting detailed performance information on response time for incoming requests, database queries, calls to caches, external HTTP requests, and more.

######################### APM Server Configuration #########################

################################ APM Server ################################

apm-server:
  # Defines the host and port the server is listening on. Use "unix:/path/to.sock" to listen on a unix domain socket.
  host: "192.168.101.24:8200"

  # Configure authorization via a common `secret_token`. By default it is disabled.
  # Agents include the token in the following format: Authorization: Bearer <secret-token>.
  # It is recommended to use an authorization token in combination with SSL enabled,
  # and save the token in the apm-server keystore.
  #
  # WARNING: This configuration is deprecated and replaced with `apm-server.auth.secret_token`, and will be removed
  # in the 8.0 release. If that config is defined, this one will be ignored.
  #secret_token:
  secret_token: "<input password>"
#-------------------------- Elasticsearch output --------------------------
output.elasticsearch:
  # Array of hosts to connect to.
  # Scheme and port can be left out and will be set to the default (`http` and `9200`).
  # In case you specify and additional path, the scheme is required: `http://localhost:9200/path`.
  # IPv6 addresses should always be defined as: `https://[2001:db8::1]:9200`.
  hosts: ["192.168.101.24:9200"]
