The following is a demonstration of the hotspot.d script.
|
|
|
|
Here the script is run while a large file is copied from one filesystem
|
|
(cmdk0 102,0) to another (cmdk0 102,3). We can see the file mostly resided
|
|
around the 9000 to 10999 Mb range on the source disk (102,0), and was
|
|
copied to the 0 to 999 Mb range on the target disk (102,3).
|
|
|
|
# ./hotspot.d
|
|
Tracing... Hit Ctrl-C to end.
