In this section you can define settings for the QPR Metrics Server.

 

 

Time Interval for Replica Elements Refresh

Here you can define the settings for the time interval for refresh, which determines how often the replica elements are updated. The imported element, i.e. the replica elements, are copied from an another model and can be defined to be refreshed regularly. This can be done in the QPR Metrics client's Element Properties window's Replication Properties tab.

 

To change the settings, either enter a new value manually to the field or use the arrows on the right side of the field to scroll to the desired value.

Start date: Defines the Start date for refreshing data. The updating does not take place before the Start date.

Start time: Defines the Start time for refreshing data. The updating does not take place before the Start time. The Start time can be set by an accuracy of 5 minutes.

Interval days / hours / minutes: Defines how often the replica elements are updated. The Interval can be set by an accuracy of 5 minutes.

 

 

Remote Model Export

Here you can define the settings for responding to model requests, which determines how to operate when a remote server requests a model from the local server.

 

If the model is reserved, repeat export attempts: Tick this check box to repeat the attempt to export the model in the cases where the model is reserved, e.g. the user is editing the model at the same time when the remote server requests the model from the local server.

every __ seconds: Defines how often the export attempts are done. To change the value, either enter a new value manually to the field or use the arrows on the right side of the field.

for __ minutes: Defines how long the export attempts are done. If the model is still reserved after the export has been attempted long enough, the exporting of the element fails. To change the value, either enter a new value manually to the field or use the arrows on the right side of the field.

 

For example if you have defined the exporting to be done every 5 seconds for 3 minutes, the exporting is retrieved at 5 seconds intervals for three minutes or until the export succeeds.

 

 

Memory Usage

The Maximum memory usage setting defines the maximum amount of memory in megabytes that QPR Metrics Server and Plugin are allowed to use before non-critical caches are cleared and all measure values in all models are written to QPR EMS (Extended Memory Storage). QPR EMS is used by QPR Metrics Server and QPR Metrics Plugin as an extension to the memory for storing information such as measure values and calculation rules. Setting this to 0 (default) disables the limit. Otherwise the minimum value is 128 and the maximum value is 3072. This setting should be used only if you are experiencing problems with memory consumption.
