Defining Log File Name and Trim Time Section 3Element Management System (EMS) 4.0 User Manual323.5 Defining Log File Name and Trim TimeUsing the Preferences window (shown in Figure 16 on page 30), you can perform the following tasks related to the EMS log file:• Select the directory (folder) where the EMS log file is stored.• Change the EMS log file name (EMSlog by default).• Define the trim time.EMS Log File—is a system-created file into which EMS periodically places network status information. This status information includes all parameter values and all alarm states for all NEs currently connected to the system. By default, EMS places new entries into the log file at time intervals of 30 minutes. This time interval can be changed for EMS as a whole, or for any particular NE, using a SET RECORD command in the NOC-NEM window. EMS also writes a status entry into the log file whenever any alarm changes in state (for example, from “no alarm” to “major alarm”). The log file can be viewed using a browser such as Internet Explorer (for more information, refer to Topic 3.15, Viewing the EMS Log File, on page 53).Trim Time—is the number of days that a log file entry remains in the file before it is automatically deleted by the system. When any entry reaches an age in days exceeding the trim time, the entry is deleted. EMS trims the log file once every 24 hours. Maximum trim time allowed is 60 days.NOTE: To avoid losing the entries trimmed from the EMS log file, you should periodically copy and paste the log file into another log folder. To do this, use Windows Explorer copy and paste functions. Save the file with a unique name such as the log file name plus the date on which the file was copied.To display the Preferences windowSelect EditÞPreferences.
