---------------------------------------
Summary: Add "process last N builds for trend" in jenkins
configuration.
Key: JENKINS-13372
URL: https://issues.jenkins-ci.org/browse/JENKINS-13372
Project: Jenkins
Issue Type: Bug
Components: performance-plugin
Affects Versions: current
Environment: Performance Plugin 1.7
Reporter: Piotr Czachur
Assignee: Manuel Carrasco
Generating trend graphs in case there are hundreds of builds is very resource
intensive task. Currently there is an option for setting this limit in browser
cookie (btw I have just filled issue - it doesn't work) but before user set it
to explicit value, all available builds are taken into consideration. This can
be very bad and block Jenkins from responding because it's crazy busy parsing
gigs of data.
Cookie has also important disadventage: can expire, be cleared and is attached
to one browser. If user logs in from another location limit setting is lost.
My proposition is to add this limit to Jenkins "Configure System" page just
like it's done for many popular plugins.
Cheers!
