  Today, I would like to collaborate with the community about  the real usage of Insight for Jira in world instances and provide my feedback. As we know on Cloud, Insight for Jira has a limit of  400k objects for Enterprise subscription , 60k for other situations on the Cloud. So for the on-premises releases Insight for Jira has not any limitation, except  heap size requirement.   Objects in Insight JVM memory ~10.000 4Gb ~100.000 8Gb ~500.000 16Gb ~1.000.000 32Gb ~2.000.000 64Gb ~5.000.000 128Gb Note the next info: remember to always test the memory consumption in a test environment for a huge data set, because it's not always the number of objects, but the content of the object attributes as well at play.  i.e. one of my instance has  Jira/JSD/JSM version:  8.13.9 (3 nodes in DC) Insight version:  8.7.9 Java version:  11.0.11+9 GC Strategy:  G1GC   Heap Size:  38 GB Count of Objects:  1.6 mln objects Count of Units (Attribute values):  49 mln units At the moment, it works well, b

  Hello,  Today I would like to share a small story about the performance improvement of Confluence for one large company. They used that installation for more than 3.2k requests per minute based on the daily stats from frontend reverse proxy logs. The architecture of that is quite simple based on the reverse proxy (nginx),  Confluence app (tomcat), PostgreSQL as RDMS.  All those services work on CentOS 7.  On Confluence in (Tomcat logs and application logs), nothing informative logs were.  So in dmesg I found quite simple information about SYN flood on the Confluence app side. Of course, it’s quite crazy to see that situation in an organisation in  2020 ’s. # dmesg | tail [  734.711105] systemd[1]: Started Journal Service.

  Hi!  Today I would like to share just one of the customisations related to the UI. Of course, it's a small AJS, AUI trick :)   Still, most of my Jira instances are DC and Server.  And quite often request to see the standard Log work button on the next panel.  instead of here   That’s easy to set via console log: snippet: const logButton = '<a id="new-log-work" title="Log work" class="aui-button toolbar-trigger issueaction-log-work" href="/secure/CreateWorklog!default.jspa?id='+JIRA.Issue.getIssueId()+'" resolved=""><span class="trigger-label">Log Work</span></a>'; AJS.$('#opsbar-opsbar-operations').append(logButton);    We can set that change into an Announcement  banner  or use some app,  like JSincluder.  You can in marketplace or in github.   Hope it helps. Cheers, Gonchik

  Hello community,    Today, I would like to share a small snippet sql request to cleanup Insight object histories.  In the future, I will be happy to see the configuration in the Insight app as a retention policy. ( Please ,  Atlassian  provide retention policy feature in Insight)   We have 2mln+ objects in Insight, not so far, at the moment we do a cleanup and review existing potential weaknesses and improve performance of our Jira Service management DC setup.  Once our web navigation Insight tab was slow, If we do cleanup of history it starting to be fast then do review of records.  Every night our system syncs up with SAP, IdP and other external systems, also, event based sync up and updates objects from remote systems.  Therefore potential weakness is duplicated history, because change log we don’t need to keep longer than 3 months, as change log keeps on master systems.  Also, the next query helpful to find misconfigs.  SELECT hist."ID", hist."AFFECTED_ATTRI

Hi community,    Today I would like to share a small snippet to investigate DB and RDBMS PostgreSQL.  Before starting to check and do “explain analyze” of slowest and frequent slow queries I do: select sum(xact_commit) as commits, sum(xact_rollback) as rollbacks from pg_stat_database; Just to understand how often we  meet with rollbacks. I do recommend to run a few times that query with a small timeout to understand frequency.    Next one is used and remained connections  query : select max_conn,used,res_for_super,max_conn-used-res_for_super res_for_normal from  (select count(*) used from pg_stat_activity) t1,  (select setting::int res_for_super from pg_settings where name=$$superuser_reserved_connections$$) t2,  (select setting::int max_conn from pg_settings where name=$$max_connections$$) t3; After we are ready to check the  status of connections . Helpful to plan pooling. with states as    (select datname, client_addr, case        when now() - state_change < interval '10 seco
