You also asked: > what one of these would I use to graph how much memory I am useing? > enterprises.ucdavis.memory.memTotalSwap.0 = 131504 > enterprises.ucdavis.memory.memAvailSwap.0 = 131504 > enterprises.ucdavis.memory.memTotalReal.0 = 192872 > enterprises.ucdavis.memory.memAvailReal.0 = 88588 > enterprises.ucdavis.memory.memTotalFree.0 = 220092 > enterprises.ucdavis.memory.memMinimumSwap.0 = 16000 Apart from the real memory in your machine, you can also use virtual memory. This is called swap. It is a bit more complicated than I'm going to describe here but it is sufficiently explained for this purpose: When you run out of memory, (parts of) programs that are not in use at the moment are taken out of real memory and placed on disk in the swap area. When your computer needs those programs again, another program is placed on the swap and the desired program is loaded back into real memory. Memory in use can therefore be memTotalReal.0+memTotalSwap.0 and memory in use can be (memTotalReal.0+memTotalSwap.0)-memTotalFree.0 I don't know how UCD snmp handles this but it is common to count the number of memory pages, size is then 512 or 1024 bytes. If you are on a Linux system, have a look at /proc/meminfo cheers, -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
