After the information is filled out, click the check box to enable the SLO and then click the green "Save" icon on the top right. To undo changes, click the circular arrow button to the left of the save button. The SLO should now be visible on the Service Summary page overlaid on the respective metric chart. For example, after setting an SLO of 100mb for a service's memory utilization, you should see how the SLO compares with the service's actual memory utilization on the Memory Utilization chart. To delete an objective, click the red trash can icon next to the SLO name.
