4.2. Log file logging levels

There are several possible logging levels that you can choose to be collected in /var/log/evmsEngine.log. The "lowest" logging level, critical, collects only messages about serious system problems, whereas the "highest" level, everything, collects all logging related messages. When you specify a particular logging level, the Engine collects messages for that level and all the levels below it.

The following table lists the allowable log levels and the information they provide:
