An adaptive log system and method may include calculating a complexity of the change set, comparing a current log message with a previous log message created as a result of the test operation during a previous run, to determine a log difference between the current log message and the previous log message, determining a module sensitivity for each module of the change set, identifying a trust level of a developer of the change set, dynamically adjusting log level settings, and analyzing a serviceability of the change set made to the continuous delivery pipeline based on: (i) the complexity of the change set, (ii) the log difference, (iii) the module sensitivity of each module of the change set, and (iv) the trust level of the developer, wherein, as a function of the analyzing, the sufficiency of log messages for each module of the change set is determined.
