New Relic APM's Deployments page lists recent deployments and their impact on your end user and app server's Apdex scores, response times, throughput, and errors. Deployments will also show in any charts showing metrics for an app within the NR UI. This gives engineers more context as to what might have affected application performance and when.
Herman is set up to send the Bamboo release ID and the Git revision to the New Relic application deployments REST endpoint after each successful app deploy for apps that are set up to use the New Relic agent.
Herman will show if an application was found and if an application deployment record was added. The link to the application in New Relic will be shown if the application was found in NR.
