The Top N Active DASD Activity inquiry produces two CSV files
that can be used to plot bar charts and time-series charts
using CA MICS reporting. You may select one to ten busiest
devices to be included in the CSV file.
CSV FILES:
1. Daily - DASD Usage by System & Volume
==> Four bar charts will be generated for each
system/date/volser combination. These charts
provides you the following graphics:
1) Pct Device Utilized by Hour
2) Avg Dev Response Time by Hour
3) Avg IO Service Time by Hour
4) Avg Dev Activity Rates by Hour
2. Daily - DASD Percent Busy by Hour
==> One time-series chart will be generated for each
system/date combination with one line per
volser. The chart compares how busy these
selected DASDs are.
Note: Because this inquiry does not produce a chart, no
sample is provided.
INQUIRY ID:
RMFED4
DATA SOURCE (file/timespan):
HARDVA at the DAYS timespan
OUTPUT CONTROL PARAMETER:
1. K4D4B (Four key columns, four bar charts per
system/date)
2. K3D1T24 (Three key columns, one time-series chart
per system/date)
DATA ELEMENTS USED:
SYSID - System Identifier
DATE - Date
VOLSER - Volser
HOUR - Hour
DVAPCUTL - Pct Device Utilized
DVAAVRES - Avg Dev Response Time
DVAAVSER - Avg IO Service Time
DVAACTRT - Avg Dev Activity Rate
DVAAVCNN - Avg Dev Connect Time
DVAAVDIS - Avg Dev Disconnect Time
DVAPCCNN - Pct Dev Connected
DVAAVDVB - Avg Dev Busy Pending Time
DVAAVIOS - Avg Dev IOSQ Time
DVAAVPEN - Avg Dev Pending Time
DEVNUM - Device Number
DEVCNAME - Device Name
CTLUNAME - Control Unit Name
RANK - Rank
CALCULATIONS:
DATE = MDY(MONTH,DAY,%YEAR4);
USAGE CONSIDERATIONS:
Not applicable
EXECUTION-TIME PARAMETERS:
Execution-time parameters enable you to produce a CSV
file containing just the information you want. This
reduces the:
o Amount of data extracted
o Network traffic during download
as well as makes the presentation more effective.

Enter one or more Data Base IDs for the Data Base(s) you want to process. -- Required. Specify database unit IDs (the IDs of the CA MICS database units from which files are read). To display a selection list of valid database unit IDs, specify ? (question mark). Enter range of CA MICS online file cycles or enter ARCHIVE for archive files. -- Required. These are the cycles of the specified timespan for the CA MICS files that are used as input to the analysis. You can specify a range of cycles in either ascending or descending order (for example, 01-03 or 03-01). The fields can contain any numeric value between 0 and 99, or "ARCHIVE" for archive files. Enter the range of dates (DDMMMYY) to be reported or leave blank for all. -- Optional. Specify the date range in DDMMMYY format (for example, 01OCT10). The first date range is the starting date and the last value in each date range is the ending date. The ending date must be higher than, or equal to the starting date. An input observation is selected if its date value is greater than or equal to the starting date and is less than or equal to the ending date of the specified date range. If only one value is specified, an observation is selected if its date value is equal to the specified value. Enter the range of hours to be reported or leave blank to report all. -- Optional. The first value is the starting hour and the last is the ending hour. The ending hour must be higher than, or equal to the starting hour. An input observation is selected if its hour value is greater than or equal to the starting hour and is less than or equal to the ending hour of the specified date range. If only one value is specified, an observation is selected if its hour value is equal to the specified value. Enter the SYSID(s) to be reported or leave blank to report all systems. -- Optional. Specify one or more 1-4 character SYSID value(s). Observations whose SYSID value is equal to any of the specified values are selected. If not specified, all are selected. Enter the number of most active DASD(s) to be reported (1-10). -- Required. Specify the number of busiest DASD(s) you want. Default is 5. The field must contain a number between 1 and 10.
