Integrating Microsoft IIS Server

Two versions of this plugin are available, depending on the version of the IIS.

  • Microsoft IIS (pre 8.0) Plugin
  • Microsoft IIS 8.0+ Plugin

To configure Microsoft IIS on AWS to send log data 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 IIS logs to the group IIS-Logs.

    Important: USM Anywhere expects all the log streams in a group to be the same content type (use the same plugin), in this case, Microsoft IIS 8.0+ plugin or Microsoft IIS (pre-8.0) plugin.

  3. In the USM Anywhere web UI, go to Settings > Scheduler and enable CloudWatch - IIS Logs.

    This enables USM Anywhere to find the logs automatically without your needing to create a scheduled job.

    Important: Only the Microsoft II 8.0+ plugin allows USM Anywhere to match the logs automatically. For this reason, if you need to use the Microsoft II (pre-8.0) plugin, you must schedule a job manually. For instructions, see Collect Amazon CloudWatch Logs.

    Enable the default CloudWatch - IIS Logs job in the Scheduler

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