Typically I would use the ssCpuIdle.0 to do so, but in my Linux-Version this vlaue is always 93, so I had to find an other way to do so.<br />On the Internet, I found a formula to calculate the cpu usage by using ssCpuRawIdle, ssCpuRawSystem, ssCpuRawNice and ssCpuRawUser. I transformed the formula into MRTG and looked at the graphs. Firstly I was wondering, why this is always the same value, but now it is clear: MRTG calculates the given values resulting in the average load since last clearing of the counters...<br /><br />In my opinion I (or better MRTG) would have to calculate the valuechanges within the interval of each value and then use the formula. But I don't know how to do so.<br /><br />Here is the Target formula I use:<br /><br />100 - ((100 * 1.3.6.1.4.1.2021.11.53.0&1.3.6.1.4.1.2021.11.53.0:public@123.123.123.123) / (1.3.6.1.4.1.2021.11.53.0&1.3.6.1.4.1.2021.11.53.0:public@123.123.123.123 + 1.3.6.1.4.1.2021.11.52.0&1.3.6.1.4.1.2021.11.52.0:public@123.123.123.123 + 1.3.6.1.4.1.2021.11.51.0&1.3.6.1.4.1.2021.11.51.0:public@123.123.123.123 + 1.3.6.1.4.1.2021.11.50.0&1.3.6.1.4.1.2021.11.50.0:public@123.123.123.123))<br /><br />I am using MRTG with RRDtool.<br /><br />Thanks for your help.<br /><br />Stephan</span></span></span></span></span></div> <br><br><table cellpadding="0" cellspacing="0" border="0"><tr><td bgcolor="#000000"><img src="https://img.web.de/p.gif" width="1" height="1" border="0" alt="" /></td></tr><tr><td style="font-family:verdana; font-size:12px; line-height:17px;">Neu: WEB.DE De-Mail - Einfach wie E-Mail, sicher wie ein Brief! <br>Jetzt De-Mail-Adresse reservieren: https://produkte.web.de/go/demail02</td></tr></table>
