HMI Router Counters

The System Sentry provides counters to monitor CIMPLICITY router performance.

Accumulated totals since the project started

For	Counter	Counts the Number of:
A	Messages Sent	Messages sent by the router.
A	Messages Rec	Messages received by the router.
A	RCM Requests	Connection management requests. When a viewer needs to attach to a project, it makes an RCM request.
N	Socket Errors	TCP/IP sockets are used to communicate. For example, if a cable is accidentally pulled off a socket, an error will be counted. Typically, there should not be many socket errors.

Indicators of current performance

For	Counter	Displays the
N	Messages Sent/sec	Messages sent by the router per second.
N	Messages Rec/sec	Messages received by the router per second.
N	Sockets	Sockets that are currently in use by the router. The router opens a socket for each connection to each computer. The router also uses sockets for other reasons. Example The router creates a separate connection between redundant nodes beyond the router message queue connection to show if the element has gone away. That can add extra sockets.
N	Socket Errors/sec	Socket errors per second show if there currently is a problem. For example, a cable needs to be tightened.
N	Connected Nodes	Nodes that are connected to the selected node.
E	Ports	Application ports in use by the router. This may be a well-known or anonymous port that is being sent out to a process. This indicates the current level of use.
E	RR Outstanding	Response required messages from a process that are on the router's queue waiting to be received by another process. If the router knows that the receiving process is unavailable, it informs the originating process.
