Hello Alex, then how do we deploy this formula to MRTG to monitor network threshold? I did some testing and found that I did to divide by 300sec to derive a correct network utilisation percentage to be monitored for threshold alert. Furthermore, in MRTG, ThresMaxi derives its percentage from MaxBytes which is wrong then.

___if___ the ifInOctets counter counts bytes and ifSpeed is in bits then it is correct. This is __not__ the case. Both counters are of the same type (both bits or both bytes) and thus a percentage is 100 * x/y. -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi --------------------------------- Do you Yahoo!?
