Log Context

Log “License [{}] mode [{}] – valid” classname is LicenseService.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                 }
                if (previousLicense != null) {
                    // remove operationModeFileWatcher to gc the old license object
                    previousLicense.removeOperationModeFileWatcher();
                }
                logger.info("license [{}] mode [{}] - valid"; license.uid();
                        license.operationMode().name().toLowerCase(Locale.ROOT));
            }
            updateLicenseState(license; currentLicensesMetaData.getMostRecentTrialVersion());
        }
    }
