The management log (balancer.log and controller.log) levels are initially configured in ase.conf file by setting log_level to one of the following five values. The default value is INFO:
  • FATAL
  • ERROR
  • WARNING
  • INFO
  • DEBUG
You can change the log level of management logs during run-time by using the log_level command. The log_level command works in an identical way for both sideband and inline ASE modes. In an ASE cluster set up, run the log_level command on all the ASE nodes. The change in log-level is also recorded in Audit logs. Following is an example CLI output of the log_level command to change the log-level to warn. The other values for the command are info, error, fatal, and debug. 
#./bin/cli.sh -u admin -p admin log_level warn
You can also verify the current log level by using the ASE status command. 
#./bin/cli.sh -u admin -p status
