Michael Neale updated an issue   Jenkins / JENKINS-42137 REGRESSION: A lot of unnecessary requests for pipeline run details and events Change By: Michael Neale The BlueOcean main pipeline screen (https://ci.blueocean.io/blue/pipelines) appears to be receiving events for running pipelines that are not visible, and then fetching data, creating more than expected traffic. On a regular basis this sends event from the backend to the frontend detailing things that are running. To reproduce: * Open /blue/pipelines/ in one tab * Run a job like bwalding-alwaysBlue from a classic screen in another tab * Note that /blue/pipelines/ receives events for this job and does requests. So:   * Events shouldn't realy arrive as there was nothing subscribing to that pipeline run right? * Fetching data about this uninteresting event also seems wrong. Some details: (I hope the 80shtgg3w8q5hpelba9k9 ID isn't something important https://ci.blueocean.io/sse-gateway/listen/jenkins-blueocean-core-js-1487311928759-80shtgg3w8q5hpelba9k9 {noformat} open  {"dispatcherId":"jenkins-blueocean-core-js-1487311928759-80shtgg3w8q5hpelba9k9","dispatcherInst":1238701885}   16:15:00.445 job {"jenkins_object_type":"org.jenkinsci.plugins.workflow.job.WorkflowRun","jenkins_event_uuid":"6c1358f1-f887-41bb-beb9-3228dda99df8","sse_subs_dispatcher_inst":"1238701885","job_run_status":"SUCCESS","job_name":"scratch/bwalding-alwaysBlue","jenkins_org":"jenkins","job_run_queueId":"5246","jenkins_object_name":"#2","blueocean_job_rest_url":"/blue/rest/organizations/jenkins/pipelines/scratch/pipelines/bwalding-alwaysBlue/","jenkins_object_id":"2","jenkins_event":"job_run_ended","sse_subs_dispatcher":"jenkins-blueocean-core-js-1487311928759-80shtgg3w8q5hpelba9k9","blueocean_job_pipeline_name":"scratch/bwalding-alwaysBlue","jenkins_object_url":"job/scratch/job/bwalding-alwaysBlue/2/","jenkins_channel":"job"} {noformat} Once the frontend receives those events, the frontend then makes a call to retrieve details about the run. https://ci.blueocean.io/blue/rest/organizations/jenkins/pipelines/scratch/pipelines/bwalding-alwaysBlue/runs/2/ However the important thing to note is that the bwalding-alwaysBlue job is not visible on the front screen - so the frontend is querying the backend for details on jobs that will not change the state of the front end (afaik) In a large instance that is running a lot of jobs all the time, this could be problematic.
