HA Logs

  • cmdb.ha.log – This log displays informational messages in short format. In case of exception only the message appears.
  • cmdb.ha.detailed.log – This log also has exception stack trace, and provides more details in TRACE mode. For example, each HA request has a request ID, and you can follow the request’s trace between the servers.
