Which statement is true regarding the limitation for automatically detected log files?

The correct statement regarding the limitation for automatically detected log files is that they must be opened constantly. This is an important requirement because Dynatrace needs to monitor log files in real time to provide meaningful insights and detect issues as they occur. If the log files are not continuously opened, there may be gaps in data collection, and relevant events could be missed, diminishing the effectiveness of monitoring and analysis.

Additionally, continuously opened log files allow for ongoing updates and ensure that Dynatrace can effectively process entries as they are written. This real-time analysis is crucial for applications that rely heavily on logging for performance tracking and troubleshooting.

Files having binary content, needing to be deleted within a minute, or being opened in read-only mode do not align with the requirements for automatic detection. Binary content may not provide the structured logging information required, while deletion and read-only access would hinder the monitoring capabilities necessary for effective performance management.
