Introduction to HetuEngine Logs

Log Description

Log paths:

The HetuEngine logs are stored in /var/log/Bigdata/hetuengine/ and /var/log/Bigdata/audit/hetuengine/.

Log archiving rules:

Log archiving rules use the FixedWindowRollingPolicy policy. The maximum size of a single file and the maximum number of log archive files can be configured. The rules are as follows:
  • When the size of a single file exceeds the default maximum value, a new compressed archive file is generated. The naming rule of the compressed archive log file is as follows: <Original log name>.[ID].log.gz.
  • When the number of log archive files reaches the maximum value, the earliest log file is deleted.

By default, the maximum size of an audit log file is 30 MB, and the maximum number of log archive files is 20.

By default, the maximum size of a run log file is 100 MB, and the maximum number of log archive files is 20.

To change the maximum size of a single run log file or audit log file or change the maximum number of log archive files of an instance, perform the following operations:

  1. Log in to Manager.
  2. Choose Cluster > Services > HetuEngine > Configurations > All Configurations.
  3. In the parameter list of log levels, search for logback.xml to view the current run log and audit log configurations of HSBroker, HSConsole, and HSFabric.
  4. Select the configuration item to be modified and modify it.
  5. Click Save, and then click OK. The configuration automatically takes effect after about 30 seconds.

Log Level

Table 2 describes the log levels provided by HetuEngine. The priorities of log levels are OFF, ERROR, WARN, INFO, and DEBUG in descending order. Logs whose levels are higher than or equal to the specified level are printed. The number of printed logs decreases as the specified log level increases.

Table 2 Log levels

Level

Description

OFF

Logs of this level record no logs.

ERROR

Logs of this level record error information about the current event processing.

WARN

Logs of this level record exception information about the current event processing.

INFO

Logs of this level record normal running status information about the system and events.

DEBUG

Logs of this level record the system information and system debugging information.

To change the run log or audit log level of an instance, perform the following steps:

  1. Log in to FusionInsight Manager.
  2. Choose Cluster > Services > HetuEngine > Configurations > All Configurations.
  3. In the parameter list of log levels, search for logback.xml to view the current run log and audit log levels of HSBroker, HSConsole, and HSFabric.
  4. Select a desired log level.
  5. Click Save, and then click OK. The configuration automatically takes effect after about 30 seconds.

To change the HetuEngine Coordinator/Worker log level, perform the following steps:

  1. Log in to FusionInsight Manager.
  2. Choose Cluster > Services > HetuEngine > Configurations > All Configurations.
  3. In the parameter list of log levels, search for log.properties to view the current log levels.
  4. Select a desired log level.
  5. Click Save, and then click OK. Wait until the operation is successful.
  6. Choose Cluster > Services > HetuEngine > Instance, click the HSBroker instance in the role list, and choose More > Restart Instance.
  7. After the HSBroker instance is restarted, choose Cluster > Services > HetuEngine. On the overview page, click the link next to HSConsole WebUI to go to the compute instance page.
  8. Select a compute instance and click Stop. After the instance is stopped, click Start to restart it.
