Orbix Interview Question:

How you can configure Orbix logging?

Submitted by: Administrator

Orbix logging is configured through the event_log filters. These sequences of variables set the logging level for each of Orbix's subsystem. For example, the following configures the IT_POA subsystem to display only error messages:
event_log:filters = ["IT_POA=ERROR"];

Similarly, the following sets the IT_POA subsystem to display only error messages and also the IT_PSS_DB subsystem to display only warning, error and fatal messages:
event_log:filters = ["IT_POA=ERROR", "IT_PSS_DB=WARN+ERROR+FATAL"];

An asterisk can be used as a wildcard character, either to specify all subsystems, or all message levels. For example, the following configures the IT_POA subsystem to display all messages:
event_log:filters = ["IT_POA=*"];

Similarly, the following configures all subsystems to display all messages:
event_log:filters = ["*=*"];
If unconfigured, a subsystem will display no messages.
