Jenkins / JENKINS-56833 Hundreds of REST calls to JOB_URL/runs/2/nodes/?limit=10000 Issue Type: Bug Assignee: Unassigned Components: blueocean-plugin Created: 2019-04-01 12:46 Environment: Jenkins core 2.169 BO 1.14 at least 100 build agents Priority: Major Reporter: Ivan Fernandez Calvo When you are using a high number of agents running the BO UI increase the number of request to the URL JOB_URL/runs/2/nodes/?limit=10000, this could become insane and makes that the UI blinks every time making it unusable even when the jobs are done. Steps to replicate You need a system that can provision at least 100 agents to see the behavior Execute the following pipeline three times to try to provision more than 100 agents #!/usr/bin/env groovy pipeline { agent { label 'master' } stages { stage('test'){ steps{ script { def tasks = [:] for(def i = 0; i < 50; i++){ tasks["t-${i}"] = parallelTask() } parallel(tasks) } } } } } def parallelTask(){ return { node('immutable'){ timeout(time: 90, unit: 'SECONDS') { echo "NOOP" sleep 1 } } } } Open the BO UI on one of the builds Open the Chrome inspector on the network tab, after a minute or so you will start seen tons of REST request like 'JOB_URL/runs/2/nodes/?limit=10000' and 'JENKINS_URL/blue/rest/organizations/jenkins/computers/' meanwhile every few seconds the UI will blink Add Comment

Re: Hundreds of REST calls to JOB_URL/runs/2/nodes/?limit=10000 Yea we found out that every job/stage start/top will refresh the computers stuff. JENKINS-56773 has a fix, just needs to be merged.

Re: Hundreds of REST calls to JOB_URL/runs/2/nodes/?limit=10000 I think I'm still seeing this currently with the Blue Ocean Aggregator 1.22.0

I think I'm still seeing this currently with the Blue Ocean Aggregator 1.22.0

!BO-Network.png! !BO Nodes and Stuff.png! It also gives like... a pretty sexy view that's just locked to the bottom of the last step of the stage view. No matter where you scroll, the ?limit=10000 request gets made and the view is reset and snapped back to the bottom of the page. It's a super frustrating user experience.

Ryan Fenton-Garcia Please open a new issue This one was resolved by making executor info an optional plugin, so only those that need it (and I recommend you uninstall the executor plugin), and doesn't break things, can have it installed if its hitting a different endpoint. Its a new bug, and the new owners will need to take a look at it

Re: Hundreds of REST calls to JOB_URL/runs/2/nodes/?limit=10000

That's actually extremely helpful to know! Do you know what kind of things the executor info plugin actually provides? I tried to look at the github page for the plugin, but I only see a link to a presentation that I'm not sure what is or isn't specifically related to the plugin. Also, do you know what other plugins that potentially degrade blue ocean's performance are optional?
