Integrating Apache Web Server

Before configuring the log collection, you must have the IP address of the USM Anywhere Sensor.

To configure Apache to send log data to the USM Anywhere Sensor

  1. Enter

    ErrorLog syslog:local1

    This tells Apache to send the error log output to the syslog facility called local1.

    You must also tell your syslog server to send this log output to the USM Anywhere Sensor and to write it to a log file.

  2. To send log entries to the USM Anywhere Sensor, enter


To send Apache log data on AWS through CloudWatch

  1. Follow the instructions on the AWS website to install the CloudWatch Agent on your host.

    Note: If you choose to enable CloudWatch Logs in your Amazon Web Services (AWS) environment, you should make sure that you are not collecting more data than you need because this service incurs AWS costs based upon usage. See the CloudWatch pricing information to plan and configure your usage.

  2. Configure the agent to send Windows logs to the group Apache-Access-Logs.
  3. In USM Anywhere, go to Settings > Scheduler and enable the CloudWatch - Apache-Access-Logs job.

    This enables USM Anywhere to find the logs automatically.

    Enable the default Apache-Access-Logs job in the Scheduler

  4. Wait for events to appear in the Events page.

Plugin Enablement

The Apache plugin automatically processes all messages that have "apache" as the syslog tag.
