- OS command ?
- vmstat 1 2 (used in menu system - statistics -memory or via CLI)
- arcstat.pl (used in menu system- statistics - arc)
In doubt, I would trust the CLI commands like vmstat.
During usage, nearly all otherwise not used RAM is assigned as read cache. Maybe this is excluded by your command. It is quite normal for Solaris based systems to have only minimal free RAM due to this behaviour as this gives you a value for your RAM: performance.
Hi Gea, I didn't run a specific command, I used the OI version of Task manager (forget what it's called- system something or something).
it quite clearly shows that only 360mb-ish of ram is used but Napp-it is showing almost complete memory useage - i will try the other commands tonight to double check
