Physical memory monitor

It is important to monitor the physical memory on each computer in your system in order to prevent failure.

The Network Management Console (NMC) uses the physical memory monitor on each computer within your AVEVA Enterprise SCADA system to monitor physical memory space. You can configure each computer for:

• A warning condition.

• A failure condition.

To ensure that its configuration is consistent, the physical memory monitor stores any properties within the local computer registry. When you start the physical memory monitor, it reads this configuration from the registry and publishes this information through the PubSub.

When the physical memory monitor publishes a failure status (or alternatively an OK status), it publishes a message to both the NMC physical memory monitor snap-in and the arbitration health server. The arbitration health server takes any arbitration actions required, as illustrated in the figure below.
