NetXMS Support Forum

Yes, it must be named "Dummy". This is what I wrote in my previous message:

You can create additional DCI with source "Internal" and name "Dummy" (of course description can be any).

You can change description of the DCI, but not the name. Description is a free form text intended to be read and understand by humans, but name is a parameter's identifier understandable by server and/or agents. "Internal" origin means that values for these parameters generated by NetXMS serer itself, without asking any external entities. One of supported internal parameters is named "Dummy", and it always returns 0 when polled for value. It was added specifically for providing "ticks" for calculated DCIs.

So it is not a "workaround", it's just correct system configuration

Best regards,

My mistake to overlook that "Quotation"  though "Quotation" is my practice as well.

I'm indded sorry for that unusual term. However I's not only pointing about this "Dummy" problem. I've co-related all my experience with NetXMS, like Cluster node disapper, OS hang without n/w, etc. For this "Dummy", if you cannot allow any other name then can't it make some select-only/drop-down type input there?

Finally Yes, this thread can be closed but this has something to go into Mantis

Can I create DCI for dummy summary node with help of Array as below?
array monitornodes;
monitornodes = {"system-1" , "system-2", "system-3"};
summary=0;
for (i=1; monitornodes != NULL ; i++)
{
  inode = FindNodeObject($node, monitornodes);
  ivalue = GetDCIValue(inode, FindDCIByDescription(inode, "TotalAuth"));
  summary = summary + ivalue;
}
return summary;

I see array initialization is not been supported as above syntax. However I get success with below syntax
array monitornodes;
monitornodes[1] = "system-1";
monitornodes[2] = "system-2";
monitornodes[2] = "system-3";

My point of asking is primary about array initialization syntax.

Hi!

The only possible initialization of array is like

monitornodes[1] = "system-1";
monitornodes[2] = "system-2";
monitornodes[2] = "system-3";

I like the idea of having array initializers, I will add it to NXSL. Also, your script has an error if for loop condition - it should be monitornodes != NULL, not monitornodes != NULL. So, correct version of the script should looks like this:


array monitornodes;

monitornodes[1] = "system-1";
monitornodes[2] = "system-2";
monitornodes[2] = "system-3";

summary=0;
for (i=1; monitornodes[i] != NULL ; i++)
{
  inode = FindNodeObject($node, monitornodes[i]);
  ivalue = GetDCIValue(inode, FindDCIByDescription(inode, "TotalAuth"));
  summary += ivalue;
}

return summary;
