Can someone give me an example of a transform script that pulls a value from a DCI table into a variable?
Line like this:
table = AgentReadTable($node, "System.Processes");
will read agent table (System.Processes in this example) into variable. It will be object variable of class Table (https://wiki.netxms.org/wiki/NXSL:Table). Then you can walk through table using it's methods. For example, to read value of column "NAME" in first row you can use the following code:
colIndex = table->getColumnIndex("NAME");
value = table->get(0, colIndex);
You can iterate through table using rowCount attribute as stop indicator:
for(row = 0; row < table->rowCount; row++)
{
value = table->get(row, colIndex);
}
Best regards,
Victor
P.S. If you meant transformation script of a table DCI, then you don't need to read table - variable $1 will hold table object.
