What does the Solaris client use to get this data? vmstat? (free is not a native solaris tool).

Could you show me the client data behind this report? Assuming you have the "hostdata" task running, it should be available from the historical status log via the "Client data available" link near the bottom of the page.
It is the "[free]" section that is interesting for the memory report.
Here are two separate [free] sections (from history), that resulted in red alerts:
[free] total used free shared buffers cached Mem: 3921396 3894772 26624 0 302132 3887292 -/+ buffers/cache: 18014398509187332 4216048 Swap: 2104472 904 2103568
- and
[free] total used free shared buffers cached Mem: 3921396 3851576 69820 0 319192 3903296 -/+ buffers/cache: 18014398509111072 4292308 Swap: 2104472 904 2103568
I have to plead "not guilty" on behalf of Xymon, then. The data reported by "free" in the "+/- buffers/cache" line is obviously bogus - but it is what Xymon uses for the "Actual" memory calculations. If Xymon gets bogus data, then you will also have bogus results.
