Re: Build stats graph configuration lost after Jenkins Restart

I can confirm this is an issue with our RHEL5 Linux server with Jenkins ver. 2.23, and plugin 1.4 revison.

Solution:
I confirmed the .../jenkins/global-build-stats/jobresults/ directory contained two jobResults... files, one of which, jobResults-2016-04.xml, contained only "<null/>". The other file appears to contain the build results as you would expect. I removed the jobResults-2016-04.xml file and did a safeRestart on the machine. The graph survived the restart process so I'd say this was the cause of our issue. Hope this helps others.

(i) Removing a job results file containing "<null/>" at {{../jenkins/global-build-stats/jobresults/jobResults-2014-07.xml}} fixed this issue for me too.

I've encountered similar issue. I'm gathering data from 9 Jenkins instances (will be more soon).
Charts are dissapearing on one of them after safeRestart. Please see some details below.
root@*******:/home/jenkins/jenkins# ls -al global-build-stats.xml
rw-rr- 1 jenkins bm 22064 Jan 7 19:20 global-build-stats.xml
root@*******:/home/jenkins/jenkins# ls al global-build-stats.xml #<-- after (

{jenkins_url}

/safeRestart)
rw-rr- 1 jenkins bm 220 Jan 7 19:27 global-build-stats.xml

I've found temporary workaround by restarting jenkins server (and tomcat):
service jenkins stop/start
Right now global-build-stats.xml file is not cleared but I'm wondering what was the root cause.

I've also noted that file is frequently accessed (each few minutes):
rw-rr- 1 jenkins bm 22064 Jan 9 14:06 global-build-stats.xml
(...)
rw-rr- 1 jenkins bm 22064 Jan 9 14:24 global-build-stats.xml

Would it be possible (at least) to add button to upload/reload global-build-stats.xml file to easy restore charts (I keep xml files in a separate repository) when such an issue come back again?

Jenkins ver: 2.7.4
Global build stats plugin: 1.4

Re: Build stats graph configuration lost after Jenkins Restart

I have the problem on 2 (out of 9) jenkinses and I was able to fix the issue on one of them with described: "removing a job results file containing "<null/>" at"
C:\jenkins\global-build-stats\jobresults\jobResults-2011-06.xml (the was also jobResults-2011-07.xml with "null" to remove)
Jenkins ver. 1.509.2 (installed as a service on Windows Server 2008 R2 Standard, with SP1)
Global build stats plugin: 1.3
