Cumulative Sum of Aborted Rollouts

[johnmwood]

We are currently onboarding multiple teams on Argo Rollouts. My organization would like a proxy metric for Potential Avoided Incidents. Using PromQL, I have come up with the following query to see the number of aborted rollouts:

sum(rollout_info{kubernetes_namespace="argo-rollouts", phase="Abort", namespace!~"$excluded"} == 1)

The issue here is that we can get a time series of the number of aborted rollouts but we cannot see the cumulative sum of all aborted rollouts. I have tried other queries like using sum(count(<query)) or sum_over_time({query}[3m] == 1 but they either don't fulfill the requirement or don't work due to the nature of the time series.

Is there a better way to get this kind of cumulative sum of aborted rollouts without patching the controller and adding a counter metric?
