TOTALMEMORY statement does not work properly on Linux

[Brian C]

Hi,

I just started using monit on a SuSE 9.3 server to monitor 
Apache 2, sshd, and mysql. I love it.

/var/log/messages shows this error every time monit 
starts:

Warning: TOTALMEMORY statement does not work properly on 
Linux

I assume this is a reference to the directive in my 
monitrc that reads:

 if totalmem > 500 MB for 5 cycles then restart

So, what's the story here? Does this not work on GNU/Linux 
servers? Is there a bug filed or feature request filed to 
make it work? Thanks for any info.
