Logging

By default, logging is enabled via the popular SLF4J API. Logging is optional: the driver will use SLF4J if the driver detects the presence of SLF4J API (class org.slf4j.Logger) in the classpath. Otherwise, the driver will log a single warning via JUL (java.util.logging) and otherwise logging will be disabled.

The driver uses the following logger names:

• org.mongodb.driver: the root logger
  • cluster: for logs related to monitoring of the MongoDB servers to which the driver connects
  • connection: for logs related to connections and connection pools
  • protocol: for logs related to protocol message sent to and received from a MongoDB server
    • insert: for logs related to insert messages and responses
    • update: for logs related to update messages and responses
    • delete: for logs related to delete messages and responses
    • query: for logs related to query messages and responses
    • getmore: for logs related to getmore messages and responses
    • killcursor: for logs related to killcursor messages and responses
    • command: for logs related to command messages and responses
  • uri: for logs related to connection string parsing
  • management: for logs related to JMX
