Export Data

This function helps you export the operation logs, alarm (and other data need to be exported) automatically. The operation logs, alarms (and other data) meeting the export criteria are backed up and exported to the specified path, and the exported data is deleted from the system.

Operation Procedure

1. Click the System Management tab, and on the navigation tree, click the Data Export link or click the data export icon.
   
2. On the Data Export Settings page, select a tab, for example, the Operation Log tab.
   
3. The Data Export Settings page provides the following operations:
   a. Select the By Space check box.
   b. Type the threshold for export space.
   c. Type the reserved space size after export.
   d. Select the By Time check box.
   e. Type the threshold for export time.
   f. Type the number of days for the data to be retained after the export in Export but those in last xxx Days.
   g. Select the target file type.
   h. Type the number of days for the file to be saved in Save File for.
   i. make proper settings in Execute Command After Export.
4. Click OK.

Precautions

• Data export function takes effect only after related components installed and deployed. For example: the alarm export function takes effect only after the basic network management components are installed and deployed.
• You can set the export space for only the data export type that supports setting the export space. The export space setting is exclusive with the export quantity setting.
• Modifying the system time may trigger data export. To ensure system operation, please modify the system time with caution.
• The alarm export function helps you export the recovered alarms. The unrecovered alarms cannot be exported. The parameters configured are for the recovered alarms. For example, export threshold 1000 indicates that the alarm export function is enabled when there are 1000 recovered alarms.
• If a duplicate trap, an intermittent trap, an unknown trap, or a trap of devices not in the system is escalated to an alarm, the trap can be dumped only when the alarm is recovered or does not exist.
• If the administrator selects both the By Quantity(or By Space) and By Time check boxes, the system automatically selects the export criteria that contains more entries and export the data.
• If the administrator selects only the Export Space option and does not configure the other parameters, export is performed as follows: the export space threshold is set to 10 MB, and the reserved space size after export is set to 5 MB. In each morning, the system automatically checks the records in the database. If the records reach 10 MB, the system automatically starts the export function, reserves the most recently received 5 MB records, and exports the earlier records (if the setting is for alarm export, the acknowledged alarm information is exported). Restricted by the database type and file system factors, the space size can be accurate to only the MB level.
• If the administrator selects only the By Quantity check box, the export process is as follows: When the threshold is set 8000 and the entries to be retained after the export is set 500, the system checks the entries in the database every morning. If the number of entries reaches 8000, the latest 500 records are retained and the rest are exported (For alarm export, only the confirmed alarms are exported).
• If the administrator selects only the By Time check box, the export process is as follows: When the threshold is set 30 and the entries to be saved after the export is set 15, the system checks the entries in the database every morning. If there are entries of 30 days before, the latest 15 days' entries are retained and the rest are exported (For alarm export, only the confirmed alarms are exported).
• Data export is usually exported at 02:00:00 every morning. Please ensure that the system server is not busy at 02:00:00. To modify the export time, please contact the technical support center.
• To change the export directory, click the Change Export Directory link on the upper right corner.
• To start data export tasks immediately, click Export Immediately link.The export directory can be an absolute path or relative path. If you use a relative path, the path must be created in the system installation directory.
• A command executed after the data export runs in the background service mode. Thus, you cannot open any window with this command and this command automatically exits after it is finished.
• Executing either Export Immediately or export as scheduled will trigger an export threshold check. If the threshold is not reached, no records will be exported.
• The data of the device updown alarms and interface updown alarms are large. Export of these alarms must be triggered by quantity, and is triggered by quantity by default.

Parameters

• Target File Type: The exported files can be retained in the CSV or the HTML type (For example, the file names may be 20061221171425.html or 20061221171425.csv).
• Save File for: The system checks whether the files exceeding the preset days exist in the target file path. If yes, the system deletes them.
• Target File Path: The path to save the exported files. The path is specified by the system, and you cannot change it.
• Execute Command After Export: Specify a command that needs no GUI operation. The command can be an executable or batch command.
• Last Export: The time of the latest success export.
