Foglight for Apache enables you to quickly determine the status of each of your monitored Apache web servers by providing a visual overview of key access and traffic metrics. The Apache Web Server, also known as the Apache Httpd Server, is an open-source project hosted by the Apache Foundation. Through its server status (mod_status) and server information (mod_info) pages, the Apache web server provides a wealth of performance statistics, which Foglight for Apache displays in easy to use dashboards.
NOTE: In order for the Apache agent to monitor your web server, the server must have mod_info and mod_status enabled. For more information, see Configuring Apache web servers for monitoring . |
