The "System Logs" page displays all events of a running Carbon instance. Further, it facilitates downloading and viewing log files according to user preferences. The log files can be retrieved in two ways:

  • If syslog-ng is configured, log files are taken from the remote location where the log files are hosted using syslog-ng server. 
  • If syslog-ng is not configured, log files are taken from the local file system (super-tenant or Stand-alone apps).

You can refer to more information about logs and how to set log properties in section Logging. Statistics on system logs are provided by the following feature:

Name : WSO2 Carbon - Logging Management Feature
Identifier : org.wso2.carbon.logging.mgt.feature.group
