getting memory statistics with sar

getting memory statistics with sar

getting memory statistics with sar

On most Unix flavours the sar -r command will give you real memory usage, but this does not appear to be the case on AIX. I checked the man page and I don't see another option to get real memory stats.

I know you can use vmstat to get memory stats, but unlike sar you can only get current stats and not historical stats. I need to be able to produce reports including memory usage.

Does anyone know if there is a sar option that will give me what I am looking for. Or is there another way to record and recall real memory usage?



RE: getting memory statistics with sar

Sorry to go off the point slightly.

Have you tried NMON.  Its an unsupported (but written by a nice man at IBM) utility which should produce all you need.  It provides cpu,memory,disk,etc reports which it puts out to an excel spreadsheet.  It has two parts, the app on the AIX box and the macro you need to format the data in the spreadsheet.

Try it, it works a treat!
