Apache (Windows)

This template retrieves Apache server statistics from the built-in Apache server-status web page using PowerShell script.


Perl, access to the Apache server-status page.

You need libwww-perl installed. You can install using this command: yum install perl-libwww-perl.noarch

Access Configuration

Configuring Apache to allow access to the server-status page:

  1. Log on to your Apache Windows server.
  2. Locate the Apache configuration file, typically in httpd.conf.
  3. Append the following lines to your httpd.conf. You should allow access to server-page for your domain. Replace APM_host with th IP address or hostname of Orion server.
    <Location /server-status>
    SetHandler server-status
    Order Deny,Allow
    Deny from all
    Allow from APM_host
    ExtendedStatus On
  4. Ensure that following line is uncommented and present in the httpd.conf file: LoadModule status_module modules/
  5. Restart the Apache server.


Administrator on the SolarWinds server (all monitors run locally).

Before using this template, the correct arguments should be set in all monitors. All monitors require the following arguments:



  • server – This is the hostname or IP address of the target Apache server. You should set this argument to ${IP} which automatically replaces this argument with the target host IP address.
  • server_port - This is the Apache port under which the site is running. By default it set to port 80.

The following is an example using the Scripts Arguments field:${IP},8080

If you receive the error Cannot connect to local host, refer to this article to solve.

Monitored Components

For details on monitors, see SAM Component Monitor Types.

Server Uptime

This counter returns the time, in seconds, that the server has been up.

Idle Workers

This counter returns the number of free workers ready to handle client connections. This value should be as high as possible. If you have no idle workers, or very few, Apache may be using all of the processes it is allowed and new, incoming requests must wait for older requests to finish before they can be handled. If this is the case, increasing the maximum number of allowed processes in your configuration file might help with performance.

Total Accesses

This counter returns the total number of accesses.

Total Traffic

This counter returns the total number of kilobytes this server has served.

Server Requests Per Second

This counter returns the average rate of all requests per second. The result is calculated as the total number of requests throughout the life of the server (count) and divided by the total uptime in seconds (up_time).

Server kB Per Second

This counter returns the average rate of kilobytes served per second..

Server kB Per Request

This counter returns the average number of kilobytes per request.

Busy Workers

This counter returns the number of busy workers serving requests. This counter should be as low as possible.
