BCAM CONNECTION report

This report supplies information on the data sent and received as well as bucket-specific time statistics for defined connection sets.

Report output

The REPORT BCAM statement is used to request the output of the BCAM CONNECTION report.

The report can only be output if the SM2 administrator has

• defined the monitoring parameters using the SET-BCAM-CONNECTION-PARAMETERS statement

• defined the connection sets to be monitored using the ADD-BCAM-CONNECTION-SET statement

• started the monitoring process using the START-MEASUREMENT-PROGRAM TYPE=*BCAM-CONNECTION statement

A separate screen is output for each of the connection sets to be monitored (up to 32). If the number of connections to be monitored within a connection set is zero, no report is output for that connection set.

Monitoring information

SET	Name of the connection set
# CONNECTIONS	Number of connections in the connection set. The computation includes connections that were active both at the current monitoring time and at the end of the preceding monitoring cycle, or were opened and/or closed during the monitoring cycle.
# REJECTED	Number of rejected attempts to open a connection
IN/OUT	Data sent and received
TSDU	Number of TSDUs per second TSDUs (Transport Service Data Units) correspond to application jobs on BCAM.
DATA	Average volume of data in KB per TDSU
BUFFER %	Amount of cache space occupied by unretrieved messages in KB and as a percentage of the maximum buffer size. This value describes the status at the end of the monitoring cycle, and not the mean value over the entire monitoring cycle.
PWIN	Number of packets without user data (Packet WINdow) per second
PDATA	Number of packets with user data (Packet DATA) per second
SCOM	Number of send jobs per second in the event of a resource bottleneck (Send Call Over Maximum)
ZWR	Number of packets with Zero Window Information per second, i.e. where the partner application does not allow the sending of any further data
INWAIT TIME	Time between the display of a message and the retrieval of that message from the application
REACT TIME	Time between an application’s send call and the receive call which immediately precedes it
INPROC TIME	Time between the arrival of a message at BCAM and the retrieval of that message by the application
OUTPROC TIME	Time between a send call and the transfer of the last byte of a message to the network
BUCKET	Limit values in milliseconds of the ranges within which the monitored data is arranged by order of magnitude. > indicates overflow values.
COUNT	Number of messages sent/received in the individual ranges
AVG	Average time per transmitted/received message in millseconds. Times under one millisecond for a transmitted/received message are valued as zero when caluculating the average value.

Connections which were established and/or cleared down during the monitoring cycle are also recorded.
