Device Overview Report

The purpose of this report is to observe the utilization and response time for devices of interest in your installation.

The template consists of a variable part which must be repeated for each device included in the Overview Record and a fixed part with one statement reporting the processor utilization.

Template:

-------------- Variable Part, replace vvvvvv with
-------------- the VolSer of the device
OVW(QTvvvvvv(DQTAVG('vvvvvv')))      Average IOS Queue Time
OVW(PTvvvvvv(DPTAVG('vvvvvv')))      Average Device Pending Time
OVW(DTvvvvvv(DDTAVG('vvvvvv')))      Average Device Disconnect Time
OVW(CTvvvvvv(DCTAVG('vvvvvv')))      Average Connect Time
OVW(ARvvvvvv(DART('vvvvvv')))        Device Activity Rate
                          ------------------------
OVW(CPUBUSY(CPUBSY))                 should be added at the end

You can either use the macro Create Overview Control Statements to generate control statements for any device in your installation, or you can use the function Create Exceptions which is part of the macro DASD Activity Report, pointing to your most important volumes.

If you want to use the template to monitor the two devices MVS215 and MVS217, you can create the following overview control statements:

Example:

OVW(QTMVS215(DQTAVG('MVS215')))
OVW(PTMVS215(DPTAVG('MVS215')))
OVW(DTMVS215(DDTAVG('MVS215')))
OVW(CTMVS215(DCTAVG('MVS215')))
OVW(ARMVS215(DART('MVS215')))
OVW(QTMVS217(DQTAVG('MVS217')))
OVW(PTMVS217(DPTAVG('MVS217')))
OVW(DTMVS217(DDTAVG('MVS217')))
OVW(CTMVS217(DCTAVG('MVS217')))
OVW(ARMVS217(DART('MVS217')))
OVW(CPUBUSY(CPUBSY))

The macro Device Overview Report processes converted Overview Records which have been created based on this control set.
