How to set up the period for automatic deletion of notifications

Description

The article contains instructions for the following scenarios:

• how to delete entries from the VMmanager notification center;
• how to set the notification lifetime;
• how to set up the period for automatic deletion of notifications.

Solution

Only automatic deletion of notifications is available in VMmanager. By default, entries from the Notifications → All notifications are automatically deleted after 30 days. You can set a different period for automatic deletion of notifications by adding a patch. This setting will make the Notifications section more informative and save free space on the server with the platform.

To set up the period for automatic deletion of notifications:

1. Connect to the server with the platform via SSH. For more information about connecting via SSH, see Workstation setup.
2. Create the patch file /opt/ispsystem/vm/patch_notificationttl.yaml with the following content:

   version: "3.5"
   services:
     vm_box:
       environment:
         NOTICE_LIFETIME_DAYS: <N_days>

   Comment

   <N_days> — notification lifetime in days. The value is set in step 2.
3. Apply the patch:
   

   sudo vm add-patch -p=notificationttl -f /opt/ispsystem/vm/patch_notificationttl.yaml

4. Check that the changes have been applied:
   

   sudo docker exec vm_box env | grep NOTICE_LIFETIME_DAYS 

   If the patch is applied successfully, the terminal will yield a new value for the variable NOTICE_LIFETIME_DAYS.

   Example output

   NOTICE_LIFETIME_DAYS=<N_days>

   Comment

   <N_days> — notification lifetime in days. The value is set in step 2.
