BCAM-CONNECTION

Monitored data on connection sets

The BCAM-CONNECTION monitoring program supplies monitored data for connections that are combined in connection sets. It provides monitored variables for DCAM applica- tions (with NEA names) and socket applications (with port numbers) only. Information is recorded on INWAIT, REACT, INPROC and OUTPROC times.

–The INWAIT time is defined as the time between the display of a BCAM message at an application and the retrieval of this message by the application.

–The REACT time is defined as the time between an application’s send call and the receive call which immediately precedes it. If the send and receive calls are logically linked, then the REACT time can be seen as the time it takes for the application to respond. In dialog-oriented applications, each input is normally followed by the appro- priate output.

–The INPROC time is defined as the time between the arrival of a message at BCAM and the retrieval of this message by the application. The INPROC time includes the INWAIT time.

–The OUTPROC time is defined as the time between a send call and the transfer of the last byte of a message to the network. Data transfer to the network may also be delayed by the receiving party.

In addition, statistics are recorded on incoming and outgoing data (jobs, the volume of data, packets, etc.).

The SM2 administrator can use the SET-BCAM-CONNECTION-PARAMETER and ADD- BCAM-CONNECTION-SET statements to define global and connection-specific monitoring parameters respectively.

The SET-BCAM-CONNECTION-PARAMETER statement must be entered before the first ADD-BCAM-CONNECTION-SET statement.

Global parameters

Time statistics are recorded bucket-specifically. The BUCKET parameters consist of a list of the maximum INWAIT, REACT, INPROC and OUTPROC times, arranged in order of magnitude. The ranges defined in these lists apply to all connection sets defined in the ADD-BCAM-CONNECTION-SET statement.

<integer 1 .. 99999> is an integer which defines a limit value. The number of limit values in this list implicitly determines the number of ranges. This may vary from list to list, but four limit values is the maximum.
