8.4. LOG parameter

8.4. LOG parameter
	Chapter 8. Logging functionalities

Through the LOG parameter of each resource, logging functionalities and alarms can be activated.

The following table shows the meaning of the available options:

Table 8.1. LOG parameter table

Option	Meaning
`D`	Recording of the driver state changes and/or the meaningful events in Debug Log.
`S`	Recording of the driver state changes and/or the meaningful events in the System Log.
`A`	Periodic detection of alarms. The detected alarms can be displayed using the command alarm view or by the MDFIDE panel.
`L`	On alarm detection, acoustic signal plus a message on the LCD display are generated. This function depends on activation of alarm detection by the `A` option.
`T`	Generation by the SNMP Agent of traps corresponding to any change of the driver state and/or occurring of meaningful events.

The following values are also allowed:

Table 8.2. LOG parameter table

Option	Meaning
`NO`	All the logging functionalities, alarms detection and generation, above mentioned, are disabled.
`ALL`	All the logging functionalities, alarms detection and generation, above mentioned, are enabled.
`+E`	The value `ALL+E` activates all the options and extended Log of state changes. The value `NO+E` is meaningless, so it's ignored.

Options can be combined together. Some examples:

Setting LOG:DS+E, activates the extended logging functions for Debug Log and System Log;
Setting LOG:STA, activates the extended logging functions for System Log, SNMP traps generation and periodic detection of alarm states.

Adding or deleting one or more functionalities without setting from the scratch the value of the parameters can be done using + and - characters.

Some examples:

Suppose the current value of is LOG:DSTA. By setting LOG:-A, the periodic detection of eventual alarm states is removed, leaving unchanged all the remaining options; the final value is LOG:DST;
Suppose the current value of the parameter is LOG:ST. By setting LOG:+DA, the logging function of the events on the Events Log and the periodic alarm detection are added to the already activated options; the final value is LOG:DSTA.

	Note
	The changes made to this parameter are immediately activated, without the need of initialization commands.
