6. QUEUE SUMMARY: The queue summary section provides information

about the disk queue used by the Queue Manager. The first part of the

section provides basic configuration and about the files in the queue; the

remaining subsections are discussed further below.

 NAME is the template for the queue file names, built from the

QSUBVOLUME and QFILEPREFIX

 FILES / VOL is the number of files per volume, from the

QFILESPERVOLUME attribute.

 PREALLOCATE indicates whether the file space on disk is pre-allocated or

dynamically allocated and deallocated as the files are used, from the

QPREALLOCATE attribute.

7. QUEUE SUMMARY - DISK USAGE: This sub-section shows the disk

space usage for each volume specified in the QVOLUMES attribute.

There is one line for each disk used, followed by a total line for all disks.

The final line presents the maximum usage over the measurement period

for all disks. The columns are:

 Row identification (no header). The rows in this table are:

o $<disk>: these rows contain the current usage for the specified

disk.

o TOTAL: this row contains the current usage over all disks.

o MAX USED: this row contains the maximum usage over the

measurement period for all disks.

 NUM is the number of files.

 ACT is the number of files that are active, that is, that have data that

either has not been sent or may need to be resent on a restart.

 AVAIL is the number of files that are available for saving data.

 ROLL is the number of files that are currently rolling. Note: ROLL will be

0 for the MAX USED line; they are considered available in that context.

 ALLOC is the total space allocated.

 USED is the total space in use.

 % USED is the percentage of the allocated space that is used.

8. QUEUE SUMMARY – ADT POSITION: This sub-section contains

information about the position in the audit data trail (ADT) of various

events related to the queue processing. Information about the last event

received from the Collector, the last event sent to the Consumer, the

Collector restart point and the Consumer restart point are presented. The

information includes:

 Row identification (no header). Identifies the information in the rest of

the row. The rows include:

o COLL (LAST RCVD): this is the ADT information for the last event

received and buffered for writing to the queue from the

Collector.
