Summary
Poor performance is mostly visible from the lack of response in the website. The initial login page would display fine however the loading of subsequent pages and navigation through the site is not appropriate. It would be several minutes for a new page to load once it was clicked on at the worst times. Whilst this was occurring, it was noticed that the CPU on CUIC VM would often hit 100%
Basic Troubleshooting Steps
1. VM resource reservation
Try to reserve the resources for CUIC Virtual Machine via vSphere :
CPU --> 2000 Mhz
Memory --> 3GB
2. Infrastructure Polling interval
Increase "Infrastructure Polling interval" from default value to 60 min. This setting can be configured at Administration > Physical Accounts > Infrastructure System parameters
Increase "Infrastructure Polling interval" from default value to 60 min. This setting can be configured at Administration > Physical Accounts > Infrastructure System parameters
3. Monitoring property
Only enable property absolutely needed. Some customer has enabled all the properties in "Advance Configuration", it can significantly contribute the slowness on the system. You can adjust this setting at Administration > System Administration > Advanced Configuration
Note : As a course of troubleshooting, untick "Performance monitoring" or untick everything and monitor if the problem goes away.
4. Map Report
Review the map report to see if there is any VM in orverload status.
5. Collect all logs and system info (Adv)
If step1 to 4 does not help, collect "All logs" and "System Information (Advance)" and escalate to BU. To collect the logs, you need to click "System Information and Logs Link Page" as shown below :
