I understand the MRTG has 2 ways of dealing with unknowns. The default is to assume the previous value, and the other option is to assume zero.
However, while computing a large expression from different hosts, specifically an average in my case. If any of the values in the expression or unknown then the whole target reverts to either zero or flat line. For example, I'm trying to get the average cpu usage in a room (among many other averages ram usage, disk usage, network throughput), if host A goes offline for whatever reason I would prefer that the calculation go on assuming that Host A's cpu usage is zero(or use the previous value of host A's cpu usage) and have the calculated target still give out a meaningful value instead of it reverting to zero or the previous value of the target. Is there anyway to do this? -- David Grohmann Senior Student Associate Applied Research Lab : UT Austin : ESL - S206 Office: 512-835-3237 Cell: 210-861-6882 -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
