Which statement is true when configuring external log hosts for IBM Watson applications on Bluemix?

When configuring external log hosts for IBM Watson applications on Bluemix, the ability to stream logs to an external log host is an important feature. This facilitates better log management and monitoring, allowing developers and administrators to direct and analyze logs outside the standard infrastructure provided by the cloud platform. Many organizations prefer sending logs to a centralized logging solution for easier access and insights, especially for security and compliance requirements.

Using external log hosts enhances the flexibility and scalability of log management, enabling integration with various log analytics tools and frameworks. This configuration supports a broader ecosystem where logs can be filtered, searched, and analyzed according to specific organizational needs.

The other options suggest limitations or misconceptions about the capabilities of Bluemix with respect to log configuration. However, the ability to stream logs allows for more robust and effective monitoring and troubleshooting of applications deployed in the cloud.
