You can edit an existing Service from the manage option. From the manage dialog, you’ll be able to add properties to your Service, change which instances belong to your Service, add your Service to a Service group, add an IP address or DNS name for your Service, and change what metrics are aggregated.

Edit Service membership
To change which instances belong to a Service, simple edit an existing row, add a new row, or delete an existing row from the ‘Members’ section of the manage dialog. Note that we suggest that you make this membership dynamic. See the Adding Service help page for more detail.
Add an IP address / DNS name
You can add an IP address or DNS name for a Service from the manage dialog. You may want to do this, for example, if your Service represents a cluster that has its own IP address.
Edit aggregate datapoints

You can also edit the DataSource that was auto-created during the Add Service wizard directly - it is just a regular DataSource with a new collection method of ‘Aggregate Data’, where datapoints specify what data should be aggregated and how.
Edit service level thresholds
Thresholds can be changed on the Alert Tuning Tab for the Service-level DataSource:
