Agent log configuration

Log management options

When the application server runs, it starts collecting the monitoring data. The collected data is stored in the log file.

log_rotation_enabled Boolean

Default true

The function to store agent log files by date is activated. The log file name is stored in the format of whatap-'yyyymmdd'.log. If the value is false, the log file name is stored in the format of whatap.log.
log_keep_days Int

Default 7

It sets the log file retention period. It works only when log_rotation_enabled is true.
log_datasource_lookup_enabled Boolean

Default true

The function to record the log is activated in case of DataSource upon InitialContext Lookup.
log_root String

You can set the path for the agent log files. The logs folder is created under the specified path, and the WhaTap log files are generated in this folder.

If you set an agent option as in the following example, the path for creating the whatap log file is as follows:

/Users/sample_user/workspace/nodejs_application/whatap_logs/logs/
whatap.conf
```
log_root=/Users/sample_user/workspace/nodejs_application/whatap_logs/
```

In Node.js agent 0.5.1 or later, the LogSink feature is provided for integrated application server monitoring.
