By default, when any of the EVMS interfaces is opened, the Engine logs the Default level of messages into the /var/log/evmsEngine.log file. However, if your system is having problems and you want to see more of what is happening, you can change the logging level to be higher; if you want fewer logging messages, you can change the logging level to be lower. To change the logging level, specify the -d parameter and the log level on the interface open call. The following examples show how to open the various interfaces with the highest logging level (everything):
GUI: evmsgui -d everything |
Ncurses: evmsn -d everything |
CLI: evms -d everything |

If you use the EVMS mailing list for help with a problem, providing to us the log file that is created when you open one of the interfaces (as shown in the previous commands) makes it easier for us to help you. |
The EVMS GUI lets you change the logging level during an Engine session. To do so, follow these steps:
Select
-> -> .Click the
you want.The CLI command, probe, opens and closes the Engine, which causes a new log to start. The log that existed before the probe command was issued is renamed /var/log/evmsEngine.1.log and the new log is named /var/log/evmsEngine.log.
If you will be frequently using a different log level than the default, you can specify the default logging level in /etc/evms.conf rather than having to use the -d option when starting the user interface. The "debug_level" option in the "engine" section sets the default logging level for when the Engine is opened. Using the -d option during the command invocation overrides the setting in /etc/evms.conf.
