Understanding Inter-System Publish/Subscribe (ISPS) performance counters

Inter-System Publish/Subscribe (ISPS) performance statistics are published as Windows Performance Counters, under the OASyS DNA Inter System PubSub category. When selecting a particular counter, select Show Description to display a short description of the data being collected.

These performance counters are collected from the perspective of the local PubSub system agent and record the subscriptions and publications exchanged between SCADA systems.
