Description
The DISPLAY IOSTATS command is used to display logged input/output statistics. SET IOSTATS must be ON for I/O statistics to be logged.
Environment settings
The first part of the display shows current settings (certain are internal and cannot be changed):
- cluster
- replication
- iologging
- syslogging
- iostats
- dcache
- fcache
- icache
- dcache
- development
- compile
- locktype
Statistics
The statistics follow:
- opens
- creates
- closes
- icreates
- iopens
- icloses
- reads
- writes
- deletes
- appends
- dcachereads
- dcachewrites
- icachereads
- icachewrites
- ireads
- iwrites
- gcachereads
- gcachewrites
- gcachehits
- gcacheturns
- readlocks
- writelocks
- unlocks
- fstatfs
- keystrokes
- popens
- pcloses
- doprocs
- dofuncs
- copies
- disk reads
- disk writes
- elapsed time
- disk operations
- locking operations
DISPLAY commands differ from LIST commands in that they pause every screen until a key is pressed. You can cancel any further output at this point by pressing the [ABANDON] key. Where the output is sent to a file or printer, the pause is disabled.
Output keywords
| Keyword | Description |
|---|---|
| TO FILE <file> | The display output will be sent to the specified file. The filename can be substituted with a <expC>, enclosed in round brackets, which returns a valid filename. If no file extension is specified, then ".txt" will be used. The command SET PAGELENGTH governs the output file pagination and SET PAGEWIDTH defines the width of each page. Page numbers are centered on the bottom of the page according to width. |
| TO PRINT | Syntax support only. |
