Hello NetniV,
Thank you for the reply, I wish it was that easy on linux, however when you have a lot of read/writes in linux your Cache can take up all of the Free ram, this is still treated as Free ram by the linux system. I would monitor the Cache, however this can change depending on the amount of read/writes at the time, so the only way I can think of is to either monitor the Cache+Free or the Used on the graph I use, Thold will not monitor the Used memory being it is not a data source, and I can not figure out a way to add the data sources together to monitor them.
I think the net-snmp templates do break out the linux memory usage properly (at least I thought so). I'd have to look at one I setup as a test a while ago and see if it's still configured. If it is, that may help you.
I think you miss understood what I was meaning there. I run Cacti ONLY on Linux, but I grab memory from Windows servers and Linux Servers. The NetSNMP templates are different to the standard hmib-based templates in they create a stacked graph like what you are after.
