Apache

Apache web server is an open-source, web server creation, deployment, and management software. If Apache is installed on your environment, the Sysdig agent will connect using the mod_status module on Apache. You may need to edit the default entries in the agent configuration file to connect. See the Default Configuration, below.

This page describes the default configuration settings, how to edit the configuration to collect additional information, the metrics available for integration, and a sample result in the Sysdig Monitor UI.

Apache Setup

Install mod_status on your Apache servers and enable ExtendedStatus.

The following configuration is required. If it is already present, then un-comment the lines, otherwise add the configuration.

LoadModule status_module modules/mod_status.so
...

<Location /server-status>
    SetHandler server-status
    Order Deny,Allow
    Deny from all
    Allow from localhost
</Location>
...

ExtendedStatus On

Sysdig Agent Configuration

Review how to edit dragent.yaml to Integrate or Modify Application Checks.

Apache has a common default for exposing metrics. The process command name can be either apache2 or httpd. By default, the Sysdig agent will look for the process apache2. If named differently in your environment (e.g. httpd), edit the configuration file to match the process name as shown in Example 1.

Default Configuration

By default, Sysdig’s dragent.default.yaml uses the following code to connect with Apache and collect all metrics.

app_checks:
  - name: apache
    check_module: apache
    pattern:
      comm: apache2
    conf:
      apache_status_url: "http://localhost:{port}/server-status?auto"
    log_errors: false

Example

If it is necessary to edit dragent.yaml to change the process name, use the following example and update the comm with the value httpd.

app_checks:
  - name: apache
    check_module: apache
    pattern:
      comm: httpd
    conf:
      apache_status_url: "http://localhost/server-status?auto"
    log_errors: false

Metrics Available

The Apache metrics are listed in the metrics dictionary here: Apache Metrics.
