What the heck is erl9.2?

[Yakov]

I just installed LabView 2020 and something called erl9.2 got installed. Now my firewall is going bonkers because this erl is creating like 20 network connections.

What is erl? Do I need it? Can I just remove it?

Thanks.

It appears to be related to something called RabbitMQ and Erlang.  Both appear to have been around since at least 2014, but other than that, I don't know.

Erlang and RabbitMQ are open-source components used by NI products.

Some links:

What is Erlang?

(Further down it say it is used by RabbitMQ)

I am sure they are safe. 🙂

[Yakov]

I kinda assumed that they were safe, but which LabView component requires them?

Are those Erlang and RabbitMQ going to need to be deployed to a run-time system?

I'm in a regulated industry, so I'm going to document them, list ports that they require to be open etc.

I can not find much anything about these things in NI documentation.

[RavensFan]

I know InsightCM uses them.

I don't know if any other NI software does.

SystemLink maybe?

[Yamaeda]

That'd make sense. Ericsson Language is after all tailored for that kind of Communication.

LabVIEW 2020 includes some SystemLink support out of the box, which is what is pulling along RabbitMQ and Erlang.  These components will not be included in your runtime distribution unless your application uses any of the SystemLink VIs.

[Yakov]

Yeah, I think, that is it.

Thank you, everybody.
