Poor performance has been reported in a Qlik Sense environment. End users are losing connectivity to the system. When end users are eventually able to log in after many attempts, navigation and app consumption is slow. Long response times each click are also reported.
A system administrator confirms the following:
* The network is stable and has good throughput
* The QliK Sense server is running virtual on dedicated resources with high-end CPUs
* The number of users in the system has NOT incrased
* The data model has NOT changed
* The number and size of apps have increased over time
Which combination of tools should be used to diagnose this issue?
