MonItems - between real-time counters and storage

The MonItems class is the bridge between the counters and the storage.

The MemItems class either maps the contents of an existing memory-mapped file into MonItem objects or maps registered MonItem objects into a new or existing memory-mapped file.

If you want to write a utility that accesses the counters and reads their values, see the example that exports the counters in a manner compatible with Prometheus real-time monitoring, p4mon-prometheus-exporter.cc, which is located inside the Perforce filehost location for p4source.tgz

For more information, see p4 monitor realtime in Helix Core Command-Line (P4) Reference.
