HMI Router Counters

The System Sentry provides counters to monitor CIMPLICITY router performance.

Accumulated totals since the project started

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

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.
