What physical size is a memory 'page' 1

[wmg]

Hello!

I'm trying to put together some capacity graphs and our monitoring tool tracks the number of memory pages free.

I know the amount of physical RAM installed in each box so if I could figure out what size a 'page' is, I could calculate a memory usage figure.

Thanks in advance!

#pagesize
#prtconf -v | grep -i memory

Woooohoooo - thanks for that barye!!

The pagesize command is exactly what I needed - I can now add a call to that in my script as it appears that it differs from Solaris box to Solaris box.

Excellent!

Hello Barye - sorry to bother you again....


I'm getting some really odd stats back out of our monitoring system. Sometimes, the system is reporting more memory pages free than what should be there based on ram size (kb) divided by pagesize (kb).

Is it possible that Solaris can and does dynamically change the memory page block size on the fly?

If it does then I think we'll abandon trying to get historical memory stats as the monitoring system should be storing both the block size and the free page number at one point in time to make it actually useful - and it's not.

If it doesn't, then I'm not sure what else could be getting in the way - probably some programming logic or something.... ;-)
