Description
The template available at:
Has a discovery rule "Network ports discovery" with key:
discovery[{#IFNAME},1.3.6.1.4.1.789.1.22.2.1.2,{#NODE},1.3.6.1.4.1.789.1.22.2.1.1,{#TYPE},1.3.6.1.4.1.789.1.22.2.1.15,{#ROLE},1.3.6.1.4.1.789.1.22.2.1.3,{#IFDESCR},1.3.6.1.4.1.789.1.22.1.2.1.2]
The data reported back looks like:
[{
"{#SNMPINDEX}": "8.100.99.45.99.108.45.48.50.3.101.50.100",
"{#IFNAME}": "e2d",
"{#NODE}": "dc-cl-02",
"{#TYPE}": "0",
"{#ROLE}": "2"
}]
This data fails to go through the preprocessing inside discovery section:
var data = JSON.parse(value); var descriptions = {}; var out = []; data.forEach(function(elem) { if (elem["{#IFDESCR}"]) { var parts = elem["{#IFDESCR}"].split(":"); var port = parts[parts.length-1].split(' '); descriptions[parts[0] + ':' + port[port.length-1]] = { "{#IFDESCR}": elem["{#IFDESCR}"], "{#SNMPINDEX}": elem["{#SNMPINDEX}"] } } }); data.forEach(function(elem) { if (elem["{#IFNAME}"]) { var port = descriptions[elem["{#NODE}"] + ':' + elem["{#IFNAME}"]]; elem["{#IFDESCR}"] = port["{#IFDESCR}"]; elem["{#IFSNMPINDEX}"] = port["{#SNMPINDEX}"]; switch(elem["{#TYPE}"]) { case '0': elem["{#TYPE}"] = 'physical'; break; case '1': elem["{#TYPE}"] = 'if-group'; break; case '2': elem["{#TYPE}"] = 'vlan'; break; case '3': elem["{#TYPE}"] = 'undef'; break; }; out.push(elem); } }); return JSON.stringify(out);
It prints:
Preprocessing failed for: [{..."{#SNMPINDEX}": "8.100.99.45.99.108.45.48.49.3.97.48.97",..."{#IFNAME}": "a0a",..."{#NODE}":... 1.
