Good night to everyone,

I am using the netxms and enjoying it, however i need a help.
I would like to sum some dci values from my nodes.
My nodes are inside containers Ex: Servers\Server1 , Servers\Web1
I would like to sum, For example , Network in and out and iis current users .
What is the better way to do this ?

Take a look in this thread, it discusses something very similar:

H itomaskir,

Tks for reply!
I see topic, but the sum is from values of a single node.

I need make sum of values from two nodes.
Exemple:

Node 1, = Name: Server1 , DCI NetworkIN
Node 2, = Name: Server2 , DCI NetworkIN

So how can i make a sum from DCI NetworkIN from server1 and server 2 ?

Tks!

Its pretty much the same thing:

Code Select


val1 = GetDCIValueByDescription(FindObject("node1"), "DCI1 description");
val2 = GetDCIValueByDescription(FindObject("node2"), "DCI2 description");

if (val1 == null || val2 == null)
  return 0;

return val1 + val2;

I'm trying to build a variable script to find all objects beneath a template contain and sum a value from a DCI .1.3.6.1.4.1.17713.21.1.2.10.0. that is common to every device within the container.

is there a way to take the node and DCI values and create them in a dynamic fashion? the goal is to read the total number of connected subs to an AP and have this read additional APs over time automatically. I've gotten spoiled with the auto-bind functions :)

val1 = GetDCIValueByDescription(FindObject("node1"), "DCI1 description");
val2 = GetDCIValueByDescription(FindObject("node2"), "DCI2 description");

if (val1 == null || val2 == null)
return 0;

return val1 + val2;

Find template function using https://wiki.netxms.org/wiki/NXSL:FindObject function and then iterate over children using https://wiki.netxms.org/wiki/NXSL:GetObjectChildren function and for every netObject with type Node execute GetDCIValueByDescription.
