At the Jülich Supercomputing Centre (JSC), we address this challenge with LLview, an open-source system and job reporting framework. LLview provides near real-time metrics for analysis through a web portal with role-based access for users, administrators, and support staff. In this paper, we present a series of use cases demonstrating how LLview enables efficient diagnosis and resolution of system and application issues, enhancing both reactive and proactive support for HPC users. 001048907 536__ $$0G:(DE-HGF)POF4-5112$$a5112 - Cross-Domain Algorithms, Tools, Methods Labs (ATMLs) and Research Groups (POF4-511)$$cPOF4-511$$fPOF IV$$x0 001048907 536__ $$0G:(DE-Juel-1)DB001492$$aBMBF 01 1H1 6013, NRW 325 – 8.03 – 133340 - SiVeGCS (DB001492)$$cDB001492$$x1 001048907 536__ $$0G:(EU-Grant)101033975$$aEUPEX - EUROPEAN PILOT FOR EXASCALE (101033975)$$c101033975$$fH2020-JTI-EuroHPC-2020-1$$x2 001048907 536__ $$0G:(DE-Juel-1)ATMLAO$$aATMLAO - ATML Application Optimization and User Service Tools (ATMLAO)$$cATMLAO$$x3 001048907 588__ $$aDataset connected to CrossRef Book Series, Journals: juser.fz-juelich.de 001048907 7001_ $$0P:(DE-Juel1)200513$$aSankaran, Aravind$$b1$$ufzj 001048907 7001_ $$0P:(DE-Juel1)132108$$aFrings, Wolfgang$$b2$$ufzj 001048907 773__ $$0PERI:(DE-600)2018930-8$$a10.1007/978-3-032-07612-0$$x0302-9743 001048907 8564_ $$uhttps://juser.fz-juelich.de/record/1048907/files/978-3-032-07612-0.pdf$$yRestricted 001048907 909CO $$ooai:juser.fz-juelich.de:1048907$$pec_fundedresources$$pVDB$$popenaire 001048907 9141_ $$y2025 001048907 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)162225$$aForschungszentrum Jülich$$b0$$kFZJ 001048907 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)200513$$aForschungszentrum Jülich$$b1$$kFZJ 001048907 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132108$$aForschungszentrum Jülich$$b2$$kFZJ 001048907 9131_ $$0G:(DE-HGF)POF4-511$$1G:(DE-HGF)POF4-510$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5112$$aDE-HGF$$bKey Technologies$$lEngineering Digital Futures – Supercomputing, Data Management and Information Security for Knowledge and Action$$vEnabling Computational- & Data-Intensive Science and Engineering$$x0 001048907 920__ $$lyes 001048907 9201_ $$0I:(DE-Juel1)JSC-20090406$$kJSC$$lJülich Supercomputing Center$$x0 001048907 980__ $$acontrib 001048907 980__ $$aVDB 001048907 980__ $$acontb 001048907 980__ $$aI:(DE-Juel1)JSC-20090406 001048907 980__ $$aUNRESTRICTED
