Description of problem:

The metric tekton_pipelines_controller_running_pipelineruns reports the number of Pipelines which have a Succeeded status of Unknown. This includes those in a Pending state and therefore not running

Workaround:
NA

Prerequisites (if any, like setup, operators/versions):

Steps to Reproduce

1. Connect to a k8s cluster with Tekton installed and no PipelineRuns
2. Observe the metric tekton_pipelines_controller_running_pipelineruns is 0 by port-forwarding with {{ kubectl port-forward -n tekton-pipelines services/tekton-pipelines-controller 9090:9090}} and fetching the metric with {{ curl localhost:9090/metrics -s | grep '^tekton_pipelines_controller_running_pipelineruns \d+'}}
3. Create the following PipelineRun:

apiVersion: tekton.dev/v1kind: PipelineRunmetadata: name: pipelinerun-is-pendingspec: status: "PipelineRunPending"pipelineSpec: tasks:

• name: echo-good-morningtaskSpec: metadata: labels: app: "example"steps:
• name: echoimage: mirror.gcr.io/ubuntuscript: | #Unable to render embedded object: File (/usr/bin/env bash echo "Good Morning) not found."
    # Observe the PipelineRun is not running

1. Observe the metric tekton_pipelines_controller_running_pipelineruns reports 1

Actual results:

The metric tekton_pipelines_controller_running_pipelineruns reports the number of Pipelines which have a Succeeded status of Unknown. This includes those in a Pending state and therefore not running

Expected results:

The metric tekton_pipelines_controller_running_pipelineruns reports the number of Pipelines which are in a Running state

Reproducibility (Always/Intermittent/Only Once):
