Point of Service Performance Counters (POS for .NET v1.12 SDK Documentation)
2/27/2008
The Point of Service Performance Counters service application helps applications and management tools to monitor device statistics. It is included in the standard POS for .NET Package Installer. However, it is disabled by default.
Device statistics are supported by POS for .NET Basic classes. They contain the code used by Service Object developers to implement statistics. Device statistic values are periodically saved to an XML file where they can be persisted across sessions. The POS for .NET statistics service uses this XML file to expose the statistics as performance counters that can be monitored by management tools and do not require direct interaction with a Service Object. Even if the Service Object is claimed by another POS application, the counters can still be monitored by other tools.
The service application creates a counter for any statistic that is represented by a value that may be cast to an integer.
