You have to go to Advance Alert and create a new alert for High CPU or High Memory for any node.
firstly it's necessary to configure SMTP server in Setup - Advanced Setup - SMTP Configuration menu.
Then each Alert has Notification tab where you can define email address:
For further info please visit SolarWinds documentation (Alerts - Notifications menu).
I have created the alert only for email notification and in trigger action page i added the email ids but problem is when alert is generating it generating the alert too, and alert is showing in alert dashboard,
i want only email notification.
please suggest for same.
In this case I'd recommend Data Export. You can choose to export:
1) static set of VMs (, Hosts, ..): in "Search Results" module choose VMs you want to monitor and press "Export" button
2) dynamic set based on Search Query: perform a Search Query and press "Export Results" button
Then choose attributes you want to see and run the export. As soon as the report is finished then you can run the report periodically incl. sending results over email (see Schedule reports - SolarWinds Worldwide, LLC. Help and Support for further details).
You can also create an alert with "Private" permission to hide the alert from displaying for other users.
Does one of the solutions fit your needs?
