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 Server memory usage limit setting defines the maximum amount of memory in megabytes that QPR Metrics Server is allowed to use before non-critical caches are cleared. Setting this to 0 (default) disables the limit. Setting this to a too low value may lead into Metrics server continuously trying to release more memory than is possible, potentially causing performance issues.
