An Instana agent administrator reviews the following block in configuration.yaml: com.instana.plugin.mysql with nested fields for user, password, and poll_rate set to 30. Which of the following correctly describes the purpose of this configuration block?
Select an answer to reveal the explanation.
Short Explanation and Infographic
In configuration.yaml, entries prefixed with com.instana.plugin.* configure individual technology sensors. This block provides the MySQL sensor with the credentials needed to connect to the database instance and the poll_rate defining how frequently the sensor queries MySQL for performance metrics and status data. Without this block the agent would use default autodiscovery with no authentication.

Full Explanation
In configuration.yaml, entries prefixed with com.instana.plugin.* configure individual technology sensors. This block provides the MySQL sensor with the credentials needed to connect to the database instance and the poll_rate defining how frequently the sensor queries MySQL for performance metrics and status data. Without this block the agent would use default autodiscovery with no authentication. The correct answer is 'It configures the Instana MySQL sensor with connection credentials and a 30-second polling interval'. The incorrect options — 'It creates an alert rule that fires when MySQL response time exceeds 30 milliseconds', 'It defines a monitoring profile that limits MySQL data collection to 30 metrics per polling cycle', 'It registers MySQL as a custom metric source with a 30-second data retention override' — are wrong because they do not align with IBM Instana's architecture or recommended practices for this scenario. Understanding this concept is essential for the Domain 2: Configuration domain of the IBM Instana Observability certification.
