The UI server is made up of the OMNIbus WebGUI and the Operations Analytics Predictive Insights UI component.

WebGUI tuning

The OMNIbus Knowledge Center has a section on Performance tuning for WebGUI.
It should cover what needs to be considered for Operations Analytics Predictive Insights. It is expected that this will not be necessary for a deployment where only Predictive Insights feeds to the ObjectServer, but may be desirable in a shared environment.

If the system.alarm.autoclear setting in the Operations Analytics Predictive Insights Analytics component is kept as the default “true”, then the overall number of events in the objectserver at any one time should be relatively low. Consider choosing a worst-case scenario related to a percentage of the number of KPIs.
