Before you begin reading this guide, we recommend you run Elasticsearch Error Check-Up which can resolve issues that cause many errors.

This guide will help you check for common problems that cause the log ” License mode valid ” to appear. It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts: license and plugin.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).

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());
        }
    }
