Jenkins: Performance trend is empty

[lalkhum]

I use gatling as my load test tool and I have problem viewing the performance trend.

The error is as follows.

Uncaught TypeError: Cannot read property 'CategoryAxisRenderer' of undefined

I wonder if someone also has come across this issue?

I think I'm seeing the same issue.

Jenkins ver. 1.565.2
Jenkins Gatling Plugin 1.1.1

When clicking on Gatling in the left sidebar of the Project page, it shows the Performance Trend page but there are no graphs visible on the page, along with a few console errors.

Hello guys,

First, thanks for this very nice plugin! :-)

I'm facing the exact same problem with the following versions:

• Jenkins: 1.628, running on Windows
• Gatling plugin: 1.1.1

I'm trying to visualize the performance trend with Firefox 41.0.1 and Chrome 45.0.2454.

The error shown in Firefox is attached.

Let us know about a possible workaround, since this is affecting all the major new versions.

having similar issue with firefox and chrome.
The gatling jenkins plugin version is: 1.1.1
Jenkins version is: 1.596

@slandelle can you give us any hints on why is this happening? Maybe you can enlighten us, and then, I could hack around a bit to come up with a fix (or, at least, try to). :-)

[slandelle]

I'd say that, once again, the Jenkins people broke compatibility...
Maybe something like jQuery version.

I am working on integrating Gatling to our CI process and would be great to see this bug get addressed. If there is anything i can do to help please let me know.

[slandelle]

@esramirez We're pretty busy here, sorry. Please consider contributing. Or if you can't and are really in a rush, you can also consider our support offer.

I've started digging in to this to figure out what's wrong, and so far I actually haven't been able to reproduce on a clean install of jenkins.

docker pull jenkins:1.565.2
docker run -p 8080:8080 jenkins:1.565.2

# open up jenkins on 8080, 
# install gatling plugin
# install github plugin
# install maven in jenkins system preferences
# create maven project, add git repo https://github.com/gatling/gatling-maven-plugin-demo
# add post build step for gatling
# "build now"

and it worked swimmingly for the most recent version of Jenkins as well as the specific version where I was seeing the error. So, I'm pretty confused as to what else could be causing the issue. I've asked our SiteOps people for a list of installed plugins to see if there's some unexpected conflict there.

In my case, I've found that the issue is that jQuery.jqPlot is entirely undefined, so of course none of the graphs will appear since the jqPlot library isn't available to do its job, but as mentioned, I'm not sure why this is happening, or how to fix it.

[esramirez]

i am also using jenkins 1.56.2 but i noticed there is a new version, 1.635. Have you tried it yet?

[gsmachado]

The issue remains with Jenkins 1.635.

[gsmachado]

@gempesaw, the funny thing is: the "Mean response time trend" works fine, which also uses the jqPlot object (as far as I've could see).

I'd say that, once again, the Jenkins people broke compatibility...
Maybe something like jQuery version.

Oh, I see, slandelle's comment was actually exactly the issue, I just didn't understand it! Installing the jQuery plugin along with the gatling plugin makes the problem occur immediately. Uninstalling the jQuery plugin makes the issue go away. Still not sure how to fix it yet.

I verified that with 1.596 and 1.635 but it seems pretty evident that the plugin conflict is the issue, not the Jenkins version.

[gsmachado]

Hello all,

It's an incompatibility with the jQuery Jenkins plugin (https://wiki.jenkins-ci.org/display/JENKINS/jQuery+Plugin).

[gsmachado]

Oh, yes, it seems we posted/found at the same time. :-) Good. 👍

[esramirez]

the workaround worked for me! thanks alot
