The example is based around a template which configuers ICMP Packet Loss probes. This script will loop around the nodes, collect the required DCI values. The values are then ordered and the top 5 percent discarded, the remaining entries are averaged to give the required value;

<syntaxhighlight lang="c">
sub main()
{

trace(1, "Global Ping Loss 95");
array pValue;
arrayI = 0;

foreach(parent : GetNodeParents($node))
{
trace(3, "Parent object: name='" . parent->name ."' id=" . parent->id);
if (parent->name == "all voice")
{
foreach(vNode : GetObjectChildren(parent))
{
dciName = "ICMP: Packet loss to ".vNode->name;
dciId = FindDCIByDescription(vNode, dciName);
if (dciId > 0)
{
tmpValue = GetDCIValue(vNode,dciId);
if (tmpValue != null)
{
pValue[arrayI++] = tmpValue;
}
}
}
}
}

// Sort the Array
bubbleSort(pValue);

// Apply the 95 percent rule
upTo = arrayI * 0.95;
pLoss = 0;
pCount = 0;
for(ia = 0; ia < upTo; ia++)
{
pLoss += pValue[ia];
pCount = ia;
}
p95AvgLoss = pLoss / pCount;

trace(1, "Global Ping Loss 95 Summary: arrayI=".arrayI." upTo=".upTo." p95AvgLoss=".p95AvgLoss );

return p95AvgLoss;
}

sub bubbleSort(arr)
{
swapped = true;
while (swapped == true){
swapped = false;
for(ia = 1; arr[ia] != null; ia++)
{
ib = ia - 1;

if (arr[ib] > arr[ia]){
trace(3,"swap: ".ib.":".arr[ib]." with ".ia.":".arr[ia]);
swapped=true;
t = arr[ib];
arr[ib] = arr[ia];
arr[ia] = t;
swapped = true;
}
}
}
}

sub printArray(arr)
{
for(ia = 0; arr[ia] != null; ia++)
{
trace(1,"printArray: ".ia.":".arr[ia]);
}
}
