Within a protocol I want to detect when an SNMP table result is an empty array.
When this condition is discovered I will use QAction to update a standalone parameter to alert of the null data response from the array.
When the parameter is receiving data, I'll update the other parameter again
What's the best way to detect a returned empty snmp arrays in a protocol?
it is possible to use conditional triggers for QActions. Please take a look at this. I'm assuming in your case you will create a QAction that triggers on the table parameter only when tableparameterId == "", or something along those lines. Keep in mind that check for NULL will happen before the QAction is even executed, and not inside of it.
Let me know if this helps or you have any further questions.
