|
|
|
|
This plugin monitors full activity of file system like fsstat -f .
|

See man fsstat for more details.
|
|
|
|
Tested with Solaris 10 and 11. And should work with Solaris 10 11/06 or above.

|
global zone. (see man fsstat)

In global zone, this plugin gets stats of only global zone.
|
|
In non-global zones, this plugin reports stats of the non-global zones.
|
|
|
|
