Logging Parameters (D2000)

Event logging in the system

The "Log database" dialog box in the D2000 CNF process allows setting the log database parameters. The dialog box contains a table comprising the following columns:

  • Event - category of system events,

  • Log - [Yes/No] - enables/disables logging particular event into the log database,

  • History depth [days] - [0-3650] - writing period of event into the log database (in days). Configuration of history depth in D2000 version V21.1 R73 is moved into corresponding objects of type Data purpose.

  • Use device - [Yes/No] - enables/disables event logging to output device,

  • Device - the name of an output device. The output device is the type of device, where logged data will be written. There are these types of output devices:

    • PRN, LPT1, LPT2 - output to a specified printer,

    • FileName.Ext - saving to a text file of a given name.From V21.1 version, it is possible to use Windows environment variables. Usage example: "% userprofile%\Monitoring\logon.txt". When writing to a file, the existence of directories is checked and the missing directory is created. Here, for example, the "Monitoring" directory. The file size is controlled by the max_log_size parameter that is described in the Special Settings chapter.
