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. |
Example
display iostats
