Get or Set Custom Fields

The following example illustrates how to get or set custom field values by using the SetCustomField and GetCustomField API.

function Flow_CustomMetaData (dpiMsg, ruleEngine)

  require 'LOG'

  local customName1 = "VPNData"

  local customValue1 = "Tunnel"

  local customValue2 = "SkypeTraffic"

  local customName2 = "Voice"

  SetCustomField(dpiMsg, customName1, customValue1);

  SetCustomField(dpiMsg, customName1, customValue2);

  SetCustomField(dpiMsg, customName2, customValue1);

  local customTable1 = {GetCustomField(dpiMsg, customName1)};

  local customTable2 = {GetCustomField(dpiMsg, customName2)};

  for k,v in pairs(customTable1) do

    EZINFO("Table 1: Value: ", v);

end

  for k,v in pairs(customTable2) do

    EZINFO("Table 2: Value: ", v);

end

end
