What confuses me is that Memory Info Collection is working correctly. And same to CPU info, Memory Info also use MIB: UCD-SNMP-MIB.txt. And checking from snmpwalk, both CPU and Memory info can be collected by S1 correctly. But why does the CPU info collection work with MRTG? Can any one gives me some info?</div><div><br></div><div>Thanks,</div><div><br></div><div><br></div><br><br><div><span class="Apple-style-span" style="font-family: STHeiti; font-size: 12px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>- Li Wei Nan</div><div><br class="webkit-block-placeholder"></div><div><br class="webkit-block-placeholder"></div><br class="Apple-interchange-newline"></div></span></div></div></div></body></html>
