<![CDATA[Accessing Custom Attributes from node's parent containers]]>Hi,
I have a relatively large NetXMS deployment and I have nodes organized in multi-level container hierarchy, e.g.:

-Infrastructure
|__Client1
    |___PDC
            |___Node1
            |___Node2
            |___Node3
    |___DRC
            |___Node1
            |___Node2
            |___Node3
    |___Branches
            |___East-Side
                      |____Node1
                      |____Node2
                      |____Node3
            |___West-Side
                      |____Node1
                      |____Node2
                      |____Node3
|__Client2
    |___PDC
            |___Node1
            |___Node2
            |___Node3
    |___DRC
            |___Node1
            |___Node2
            |___Node3
    |___Branches
            |___East-Side
                      |____Node1
                      |____Node2
                      |____Node3
            |___West-Side
                      |____Node1
                      |____Node2
                      |____Node3
.... and so on..

What i want to achieve is to set few custom attributes on higher-level containers (e.g. Client1, Client2) with general client-specific info such as contact details, email notification recipients, etc. that i can use in events and actions.
In order to achieve that i need some sort of Custom Attribute "inheritance" from top to bottom, or alternatively a way to access parent containers custom attributes.

Is there a way to achieve that?

I'll give it a try and post feedback.

below is an example of the script that walks all parents of a node and collects values of custom attribute "contacts" into single string separated by semicolons:

global contacts = "";

foreach(o : GetObjectParents($node))
{
	add_contacts(o);
}

println "Contacts: " . contacts;

sub add_contacts(curr)
{
	c = GetCustomAttribute(curr, "contacts");
	if (c != null)
	{
	   if (length(contacts) > 0)
			contacts = contacts . ";" . c;
		else
			contacts = c;
	}

	foreach(o : GetObjectParents(curr))
	{
		add_contacts(o);
	}
}

The only drawback is that it will not detect duplicate values. Duplicates can be eliminated like this:

global contacts = "";
global presense = %{ };

foreach(o : GetObjectParents($node))
{
	add_contacts(o);
}

println "Contacts: " . contacts;

sub add_contacts(curr)
{
	c = GetCustomAttribute(curr, "contacts");
	if ((c != null) && (presense[c] == null))
	{
	   if (length(contacts) > 0)
			contacts = contacts . ";" . c;
		else
			contacts = c;
		presense[c] = true;
	}

	foreach(o : GetObjectParents(curr))
	{
		add_contacts(o);
	}
}

Note that this script version requires server 2.0-RC1 or higher as it uses hash maps.

Best regards,
Victor

Its a bit painful, and not usable everywhere, but it might help you atleast a little.
