Factory Probe equation

trying to do an equation to determine if a node's traffic is below the avg of the other pool members traffic...here is the formula so far

channel(2075,1)/((channel(2075,1)+channel(2099,1)+channel(2107,1)+channel(4692,1)+channel(2121,1)+channel(2128,1)+channel(2135,1)+channel(2142,1)+channel(2149,1)+channel(2156,1))/10)

but when I submit it states ERROR IN CHANNEL "POOL[]" (1) : MULTIPLICATION OR DIVISION OF TWO DELTA CHANNELS. (CODE: PE2007)

Dear k4ape

That is correct. The SNMP traffic itself shows volume. PRTG computes the difference over time to get the bandwidth. These kind of channels cannot be used in all combination. To be more specific, you cannot

  • Add/subtract a delta to/from a gauge channel (and vice versa)
  • Multiply or divide two delta channels
  • Compare delta channels
