Reduce processing time by extracting all upgrade related logs into a separate file named database-upgrade_\<timestamp\>.log. You can also zip the file and attach it to upgrade history.

## Before you begin

Role required: admin.

## About this task

When the upgrade starts, the upgrade log messages are written to both the localhost_log file and the database-upgrade_\<timestamp\>.log file. When the upgrade is done, the database-upgrade_\<timestamp\>.log file is
uploaded to the upgrade history table.

## Procedure

1. Navigate to AllSystem LogsUtilities.  
   Note:  
   You can implement this step to view the extracted database-upgrade_\<timestamp\>.log file only after the upgrade is done.
2. Click Node Log File Download.  
   The database-upgrade_\<timestamp\>.log file appears in the list of log files.  
   Note:  
   The localhost_log file consists of all the logs. The database-upgrade_\<timestamp\>.log file consists of logs only related to the upgrade.

   The database-upgrade_\<timestamp\>.log file appears only if the `glide.db.upgrade.log.save_to_db.enabled` property is set to True. By default, the
   `glide.db.upgrade.log.save_to_db.enabled` is set to True.
3. Go to Upgrade CenterUpgrade History.  
   A list of upgrades shows up.
4. Click the required upgrade from the list.  
   You can see database-upgrade_\<timestamp\>.log file is automatically attached to the upgrade.  
   Note:  
   The database-upgrade_\<timestamp\>.log file gets attached only if the `glide.db.upgrade.log.save_to_db.enabled` property is set to True. By default, the `glide.db.upgrade.log.save_to_db.enabled` is set to True.
5. Download the zipped database-upgrade_\<timestamp\>.log file.  
   Note:  
   The database-upgrade_\<timestamp\>.log file has been zipped to reduce the download time.
