Hi there,
Any advice on what can be collected and looked at more than the below would be much appreciated.
There is one heavy Dataminer user who has started to observe "Cube slow > laptop slow > fan is loud" issue on a Windows10 machine running on Intel i7-10610U with 32GB RAM.
Symptoms:
- DataMiner Cube app is using 100% of CPU for a long time - and slow with its GUI responsiveness.
- Cube freeze detection! in log file with listed "Stacktrace frozen UI" thread on various MS Windows processes.
Next step is to gather info about this setup and forward it to Skyline's support team.
The following things going to provide:
1) The above snapshots of the CPU load
2) Info from the Cube > About > Connection & versions tabs
3) Cube logging file after the issue detected from C:\Users\xxx\AppData\Local\Skyline\DataMiner\DataMinerCube\CubeLogging.
4) Memory dumps - might be challenging to follow this guide Collecting DataMiner Cube memory dumps | DataMiner Docs because the user on the machine in question has no admin permissions.
Many thanks in advance for any tips & tricks on the subject!
With excellent help from Skyline team, it was noticed that the Cube was computing heavily on the \"Severity Duration\" column (this is expensive column to compute each second) in the alarm tab pages of the alarm console.
The computing took quite some CPU because the benchmark of the CPU of the laptop (CPU: Intel i7-10610U and RAM:32GB, PassMark: circa 6800) was almost the bare minimum that is needed for DataMiner Cube.
