Operating Systems Solaris File cache portion of memory on Solaris Post 302309531 by Devyn on Wednesday 22nd of April 2009 07:19:02 AM

Hi,

Thanks. Going through it I don't see any specific calculation for Page Cache total used by fs execs and libraries etc. To put it differently, I'm basically interested to know how mdb -k using ::memstat calculated the below values:

Exec and libs 9215 35 5%
Page cache 10138 39 5%

I'm interested in getting the same numbers using kstat or other built ins but can't find decent documentation or an explanation of kstat values to be able to tell what all of them mean. I'm also interested to know if this value resides within the used portion of memory as reported by vmstat 'free' field, which I would expect as I'm finding hints here and there that this portion resides elsewhere and wanted to clear this up.

Thanks,
