Thank you for putting forth your request here. You can do a configuration change to support getting alert only for an attribute that you and your alert group are concerned about. You need to use attribute alert groups for this.
Here are the steps to follow.
1. Open user alert group from Admin > User & Alert Management > User Alert Group (you can also search for it from admin tab)
2. Click on the User alert group you are interested. Create a new attribute alert group. You may select the attributes you are interested in. In the screen grab I selected memory attributes of the server.
Now, for the configured alert group only server's memory attributes are configured.
3. Now apply the user alert group for the monitor you are interested in getting alert for. You can do that by doing to the monitor list page and selecting the edit option from the hamburger icon in the far left. You can then apply this user alert group.
Now you get alerts only for memory threshold breaches. This particular alert group will not receive alert for CPU threshold breaches or any other attributes This would help you in segregating alerts among your teams.
I hope this make sense for your requriment. Feel free to get back to us for any clarifications.
