A Workstation data viewer for a metric grouping shows message "Data limited to 100 matching metrics". This is also impacting the export of all the required data i.e. data is limited to only 100 metrics.
The default workstation data viewer limit is 100 metrics and is designed to prevent a workstation performance problem.
It can be increased by adding hidden property introscope.enterprisemanager.workstation.viewerMetricLimit to the IntroscopeEnterpriseManager.properties file.
However care should be taken to avoid any negative Workstation performance impact.

The safer option is to use the Command Line Workstation (CLW) to export all the required agent metric data
To run CLW you just need a local copy of the CLWorkstation.jar file and you can run it to connect to a remote Enterprise Manager server
