upstream_response_time slow on the Doors NG application
Recently installed Jazz in a Linux VM environment running with a DB2 database.
For the past 4 weeks the performance on the Doors NG has got progressively worse and now seeing upstream response times of 70 seconds.
Edited the nginx.conf to add logging for upstream stats. Example shown:-
[19/Oct/2021:11:24:24 +1100] "POST /rm/operations HTTP/1.1" 0000SGdQuNM55oCJbrzn0m9zcAY:6c7aa753-dea4-4cf2-bf59-3ce0a3a82b65 "{\x22@context\x22:\x22https://jazz.au.lmco.com/rm/jsonldcontexts/operations.json\x22,\x22@graph\x22:[{\x22@type\x22:\x22OperationsRequest\x22,\x22operation\x22:\x22com.ibm.rrs.team.saveArtifact\x22,\x22permissions\x22:[{\x22action\x22:\x22modify\x22,\x22processArea\x22:\x22https://jazz.au.lmco.com/rm/rm-projects/Em5cI5QEeuSRJMqOnX7Jg/components/K5HoI5QEeuSRJMqOnX7Jg\x22}]}]}"request_time=77.836 upstream_response_time=77.836 upstream_connect_time=0.003
Has anyone come across this issue before ? From a system point of view all is good. Seems like an application issue.
