This monitor is available in the Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector. The Smart Agent Receiver lets you use existing Smart Agent monitors as OpenTelemetry Collector metric receivers.
Using this monitor assumes that you have a configured environment with a functional Smart Agent release bundle on your system, which is already provided for
x86_64/amd64 Splunk Distribution of OpenTelemetry Collector installation paths.
To activate this monitor in the Splunk Distribution of OpenTelemetry Collector, add the following to your configuration file:
receivers: smartagent/apache type: collectd/apache ... # Additional config
To complete the integration, include the monitor in a
metrics pipeline. To do this, add the monitor to the
service > pipelines > metrics > receivers section of your configuration file. For example:
service: pipelines: metrics: receivers: [smartagent/apache]

Apache configuration 🔗
After you deploy the monitor in the Splunk Distribution of OpenTelemetry Collector, follow these steps to configure the Apache web server to expose status metrics:
mod_statusmodule in your Apache server. Make sure that the URL you provide for your
mod_statusmodule ends in
?auto. This returns the status page as
text/plain, which the monitor requires.
Add the following configuration to your Apache server:
ExtendedStatus on <Location /mod_status> SetHandler server-status </Location>
Restart the Apache web server.
These metrics are available for this integration.
