Cloud Deploy shows metrics for how many deployments occur for a givendelivery pipeline, over time, and how many of those deployments succeed.

About Cloud Deploy metrics

All deployment metrics in Cloud Deploy have the followingcharacteristics:

• All metrics are measured per delivery pipeline.

• All metrics are for deployments to yourproduction target.

  The final target in your delivery pipelineprogressionis considered to be the production target.

• All metrics are measured for a rolling 30-day period.

  For example, the Deployments metric counts the number of successful and faileddeployments over the last 30 days.

• Metrics considersuccessful deployments, and some also report faileddeployments.

  A successful deployment is one for which the pod or pods report a ready state.The Deployment failure rate metric counts failures as a percentage of alldeployment attempts.

Cloud Deploy makes the following deployment metrics available inGoogle Cloud console:

• Deployments
• Deployment frequency
• Deployment failure rate

The Deployments metric

TheDeployments metric shows the number of successful and failed deploymentsfrom the selected delivery pipeline to your production cluster.

The Deployment frequency metric

TheDeployment frequency metric shows how often the delivery pipelinesuccessfully deploys to the production target per day. This is one of the fourkey metrics defined by theDevOps Research and Assessment(DORA) research program.

How Deployment frequency is calculated

Deployment frequency is calculated based on the number of deploymentdays, notthe number of deployments. That is, if the delivery pipeline generates fourdeployments to production on a given day, that's counted as one deployment day.

This metric is expressed per day, per week, or per month, depending on how manydeployments there are:

• If the median number of deployment days per week is greater than or equal to3, then the frequency is expressed as daily:

  ".8 times per day."

• Otherwise, if more than 2 weeks have more than 0 deployment days then it'sexpressed as weekly:

  "2 days per week."

• Otherwise, if there's at least one deployment day per month, then it'sexpressed as monthly:

  "2 days per month."

The Deployment failure rate metric

TheDeployment failure rate metric shows the percentage of deployments thathave failed.
