What is exactly Virtual Memory in Solaris?

Specs: Linux
Hello, everybody!

I had been reading about "Virtual Memory" and I would like to know what exactly it is in the Solaris -maybe in UNIX- argot. Is it the same of "swap" space usage?

How could I measure the Virtual Memory utilization of a given server?

Thanks in advance!

Yes it is. iostat would probably be the utility you should check out to measure performance of a filesystem.

Thanks for your answer, sir!

I checked the iostat command (see below) but I can't figure out which field is exactly about Virtual Memory... for example, Virtual Memory Utilization. I looked in the iostat manual but I don't understood it.

Could you give me a hand, please?

$ iostat
tty sd1 sd2 sd4 ssd0 cpu
tin tout kps tps serv kps tps serv kps tps serv kps tps serv us sy wt id
1 19 207 16 205 208 16 238 0 0 3 76 3 4 1 1 0 98
