By default, you will receive a notification each time there is a network issue no matter if it's classified as information, warning, error or critical. If you have a few number of agents, this might work for you. However, depending on the number of agents or your network stability, you might receive too many notifications.
You have two options to reduce the number of email notifications you receive.
Option #1 - Notification Preference (recommended)
By changing the notification preference, you select the minimum severity required to send you a notification. If you are receiving too many notifications, we recommend to change the preference from Information to Error. This way, you will not receive email on small network issues classified as information or warning.
You can change the preference in your profile settings (Menu -> Click on your name -> Notifications). Learn more at How can I change the notification severity level?
The notification preference is a per-user configuration so it will only affect your notifications.
Option #2 - Monitoring Template Thresholds
Increasing the monitoring template thresholds to some less aggressive values is another option. This will reduce the number of notifications since it will reduce the number of reported network issues. However, it will also change the threshold used in the application for packet loss in the network response time graphs.
Since it is also affecting the graphs, it is not the preferred option if your objective is only to reduce the number of notifications.
You can change the thresholds in the monitoring template advanced parameters. Learn more at Network Alert Thresholds Configuration.
The thresholds configuration is for the entire template so it will affect the notifications of all users in the organization.
