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:
- 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
Output keywords
| Keyword | Description |
|---|---|
| TO <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 | The display output will be sent to a printer. The TO PRINT option will default to a local printer unless the command SET PRINTER TO \\SPOOLER is issued. The print request will then be spooled to the system printer, which is defined by the environment variable DB_PRINT. |
Example
list iostatsProducts
