Dear all, I'm use snmp service and apps to check my SL 5.5 Servers, on real-time, with the software "What's Up 14.3" and I can check Ram, HDD,Networks and others. This work very fine, but I have diff. measures when check the free Ram on the ssh consoles, and use the classical tools, like "free" and "top". When the snmp report 100% of CPU in use, the "top" command, report only 72% of CPU in use. What do you think about that?? About the Ram, I found this link: http://www.rt-embedded.com/blog/archives/linux-memory-consumption/ What do you think about that?? Why the different values, reported between both tools.
