Plugin Setup

  • The Boundary Apache HTTP Server plugin depends on the server-stats module for collecting metrics. The sections below provide the procedures to enable and configure the server-stats module.

Enable the server-status Module

  1. Modify the Apache HTTP Server httpd.conf by adding the following: xml <Location /server-status> SetHandler server-status </Location>

Secure the EndPoint with a User Name and Password

  1. Create as password file to secure the endpoint. The example shown here is using the path /etc/httpd/my_password_file. $ sudo htpasswd -c /etc/httpd/my_password_file
  2. Enable authentication by modifying the <Location/> added previously as shown here : xml <Location /server-status> SetHandler server-status AuthType basic AuthName "Apache status" AuthUserFile /etc/httpd/my_password_file Require valid-user </Location>
  3. Restart Apache HTTP server reload the httpd.conf configuration.
  4. Verify that statistics are being collected by visiting http://yourserver.com/server-status
  5. To also capture the 'requests per second' metric, add ExtendedStatus On outside of your <Location /> block: xml <Location /server-status> SetHandler server-status AuthType basic AuthName "Apache status" AuthUserFile /etc/httpd/my_password_file Require valid-user </Location> ExtendedStatus On
