I just open an issue about adding the total duration trend to gatling plugin: https://issues.jenkins-ci.org/browse/JENKINS-39476
This duration is visible in the top-right section of gatling html report page, but it is probably not store in the same format as other metrics.
I am new with gatling plugin development, but I could try to contribute if the feature is accepted, and if I got some tips about how to implements this.
What do you think about this feature?
In the issue, Cédric comment about using a jenkins plugin to track the build step duration, but I can’t find one (I just found a jenkins issue: https://issues.jenkins-ci.org/browse/JENKINS-24900).
Timestamper plugin (https://wiki.jenkins-ci.org/display/JENKINS/Timestamper) can help, but it won’t be easy.
Alternatively, I could try to send the duration by email, using the email-ext plugin, but then, I will have to create the chart manually, day by day.
Would love to hear about your opinion about this!
