Also you can check the same in Execution Trackers (sys_execution_tracker) table for the name "Install Application" and calculate the starting and completion time it took for completing the installation. From the node logs, find out the application installation starting and completion time. This total time and the above progress worker/execution tracker starting and completion time should match. And with these details, we can confirm that the application installation is successful.
