Apache Integration

This integration periodically fetches metrics from Apache servers. It can parse access and error logs created by the Apache server.

Compatibility

The Apache datasets were tested with Apache 2.4.12 and 2.4.46 and are expected to work with all versions >= 2.2.31 and >= 2.4.16 (independent from operating system).

Access Logs

Access logs collects the Apache access logs.

An example event for access looks as following:

Status Metrics

The server status stream collects data from the Apache Status module. It scrapes the status data from the web page generated by the mod_status module.

An example event for status looks as following:
