Update the Apache Configuration File

Tenable Enclave Security uses a dedicated Apache configuration file, mpm-tes.conf, to manage the MaxRequestWorkers setting. This setting controls the maximum number of simultaneous requests Apache handles and should be tuned to match the size of your deployment.

Tenable Enclave Security uses higher MaxRequestWorkers values than a standalone Tenable Security Center deployment to account for increased internal service-to-service communication introduced in the Tenable Security Center 6.9 microservice architecture.

Note: If you previously customized mpm.conf in a Tenable Security Center environment, apply those same customizations to mpm-tes.conf in your Tenable Enclave Security environment.

To update MaxRequestWorkers:

  1. Open mpm-tes.conf in a text editor.

  2. Locate the MaxRequestWorkers directive.

  3. Set the value based on the number of active IPs in your deployment, using the following table:

    Active IPs Recommended MaxRequestWorkers

    Fewer than 10,000

    39

    10,000 - 25,000

    77

    25,001-100,000

    154

    100,001 or more

    307
  4. Save the file and restart Apache.
