NSM report

This report provides data from the NSM (Node Synchronization Manager) subsystem for a computer network.

Report output

The REPORT NSM statement is used to request the output of the NSM report.
The report can only be output if the SM2 administrator has activated the monitoring process using the statement START-MEASUREMENT-PROGRAM TYPE=*NSM.

The privileged user can use the SELECT-HOSTS statement to select the hosts to be displayed in the NSM report. If these include the local host, this is output in the first line, followed by the remaining hosts in the order specified in the SELECT-HOSTS statement. The header contains information on the first host for which valid data is found. If valid information cannot be found on a particular host, the string “**” appears in place of the monitored data.
Only the local host is displayed to the nonprivileged user.

Overflow screens may be requested for this report.

For further information, please refer to the description of the SELECT-HOSTS statement.

Monitoring information

MAX MSG LENGTH	Length of the NSM message buffer in the token in kB
USED MSG LENGTH	Percentage of the NSM message buffer used
CIRC TIME	Circulation time of the token in milliseconds
This data is output by the first host.
HOST	Name of the host on which the data is collected
DURATION TIME (MS)	Dwell time of the token in the host in milliseconds
#WAIT MSG	Number of messages waiting for space in the token
#LOCKSERVER	Number of lock servers Each lock server represents a resource. It is created at the first enqueue and released at the last dequeue.
TOTAL REQ (1/S)	Total number of requests (enqueue, dequeue, convert, cancel) per second
LOCAL REQ (%)	Percentage of all requests that are local requests A local request is a request in which the lock server already exists and is located on the local host.
