Log level

This dropdown lets you select the verbosity level for the log files. The options are:

Debug
Info
Warning
Error

The logging system options have an increasing level of verbosity, from the least verbose to the most verbose. Error < Warning < Info < Debug.

Error: Creates a minimalistic log, only unexpected errors are logged
Warning: Creates extra errors that might show on some operating system (OS)s, but that are generally considered as acceptable
Info: Logs relevant successful events, it shows the program’s progress (recommended)
Debug: Logs extra events that are normally useful for debugging purposes. Given its verbosity it is best to activate it only when debugging activities are involved

Execution time

This field lets you set the time that Arc will run to collect data. This is applicable for One-shot and Offline modes.

Note:

When this is set to 0, the execution time is interpreted as infinite.

Maximum disk space

This field lets you control the maximum amount of disk space in megabyte (MB) that will be used for Offline mode.

Offline archive naming strategy

This lets you select the information that will be included in the name of archive files created while running Offline mode.

Restore default

Once the settings have been saved, you can use this button to restore the default configuration.
