Newrelic Infrastructure – Apache2 Integration and Monitoring in Linux CentOS with Newrelic

Apache is an open source, cross-platform web server distributed under the Apache License version 2.0. Because of its durability, battle-tested SSL security, and dedicated user base, it’s one of the most widely used web servers in production on the Internet. The integration is available for customers with a subscription to New Relic Infrastructure Pro.

With this integration, you can use New Relic to collect valuable performance metrics and inventory data from your Apache web servers to help you gain complete visibility into your underlying infrastructure. Metrics and inventory data are sent to Infrastructure and New Relic Insights, which include pre-built dashboards of your Apache metric data. You can also easily create alert policies and your own custom queries and charts in Insights.

You can view pre-built dashboards of your Apache metric data, create alert policies, and create your own custom queries and charts.

Critical performance and health metrics for monitoring Apache web servers

The Apache Integration captures key performance metrics and attaches them to the ApacheSample event type. Using the metrics command, the integration collects the following metric data attributes:

• Requests per second, by host
• Status of busy workers
• Total, idle, and busy workers
• Bytes sent per second, by host
• Bytes sent per request, by host

The integration’s inventory command captures the version numbers from running Apache instances and from all loaded Apache modules, using Apache’s binary file.

Compatibility and requirements

• Newrelic integration is compatible with Apache versions 2.2 or 2.4.
• Apache status module enabled and configured for Apache instance.
• Apache status module endpoint (default server-status) available from the host containing the Apache integration.
• You must have the infrastructure agent installed on a Linux OS host that’s running Apache.
• nri-apache must be installed for Apache integration
