MSO monitoring and statistics provide detailed MVS resource utilization reports for a region or for all users. The information can be viewed immediately online or evaluated in MSOPRINT files. Four kinds of information are available:
|
In this section: |
Monitoring - reports MVS resource statistics for users at user specified intervals.
Short on Storage - displays console message when region reaches site-defined threshold.
Shutdown - reports summary statistics by service at termination for the MSO region.
On Demand statistics are produced whenever requested. To initiate monitoring, issue the MONITOR=ON command in either the Configuration file or from the MSO or MVS console. Any command can be turned on or off via the console. The extent of information collected is determined by the specific command set issued from the console or configuration file. All output defaults to MSOPRINT except Short on Storage messages that are also sent as non-scrollable messages to the operator console (WTO). Shutdown statistics are always produced and cannot be disabled.
These commands can be issued from MSO/MVS console only. To display statistics based on CONFIG file specifications, type:
F servername,DISPLAY STATS
To display all statistics regardless of CONFIG file specifications, type:
F servername,DISPLAY STATS,ALL
SOS_PERCENT = {nn|0}
where:
Short on Storage specifies the percentage of storage utilization, which when exceeded, will cause a warning message to be issued via non-scrollable messages to WTO and MSOPRINT. The message destination can be altered with the Enhanced Message Routing Facility.
Enhanced message routing allows MSO installations to control the printing/listing destination of all MSO messages. MSO installations can choose to route messages to the operator's console (WTO) or MSOPRINT or both.
Enhanced message routing is implemented by adding a control character to the MSO messages found in the members MSOERR1 and CMSO1ERR of the PDS prefix.ERRORS.DATA.
Standard MSO error messages look like this:
00000(MSO12345) TEXT
Enhanced routing replaces the blank field in position 16 (before text) with:
|
b,B |
to route the message to both the console and MSOPRINT. |
|
p,P |
to route the message to MSOPRINT only. |
|
w,W |
to route the message to the console only. |
|
_ |
Blank defers to the default output destination. |
If storage utilization falls below the defined SOS_PERCENT, a message is issued stating that the storage constraint has been relieved and the WTO message is deleted (unless suppressed by the Enhanced Message Routing Facility). The SOS_PERCENT check, if active, is made at every MRM_INTERVAL interval (MSO Resource Manager Interval).
Specifying 0 disables the SOS monitoring facility. SOS monitoring may be enabled or disabled dynamically by setting SOS_PERCENT to a non-0 or 0 value, respectively.
APF authorization is required.
These commands can be issued from either the MSO or OS/390 consoles.
Using MSO console:
MONITOR = {ON|OFF}
where:
Using OS/390 console:
F servname,MONITOR ={ON|OFF}
where:
MONITOR OFF resets current setting for MN_USER, and for MN_INTERVAL, etc. to original values in the CONFIG file. APF authorization is required.
Using MSO console:
MN_INTERVAL = nnn
where:
Using OS/390 console:
F servname,MN_INTERVAL = nnn
where:
Default: 1800 (30 minutes).
APF authorization is required.
Using MSO console:
MN_STORAGE = {OFF|ON}
where:
Using OS/390 console:
F servname,MN_STORAGE = {OFF|ON}
where:
To turn monitoring on, set MONITOR=ON.
APF authorization is required.
Using MSO console:
MN_REGION = {OFF|ON}
where:
Using OS/390 console:
F servname,MN_REGION = {OFF|ON}
where:
To turn monitoring on, set MONITOR=ON.
APF authorization is required.
Using MSO console:
MN_USERS = {OFF|ALL}
where:
Using OS/390 console:
F servname,MN_USERS = {OFF|ALL}
where:
To turn monitoring on, set MONITOR=ON.
APF authorization is required.
