SAM 6.2.4 Port Requirements

In reading through the release notes for SAM 6.2.4 it specifies in the Before your upgrade! section that SAM 6.2.5 has new port requirements. Specifically it lists TCP/5671 (Rabbit MQ messaging), TCP/177991 (Agent comms to server 2008 R2), and TCP/17778 (SW Info Service, Agent Comms to Server 2012). My question is does this traffic originate from the polling engines to monitored nodes or are the comms over these ports end point/node initiated to the polling engines. Trying to determine requirements for firewall rules.

Thanks in advance

Well, we can summarise shortly, that RabbitMQ is alternative for MS Message Queuing (MSMQ).

But it says nothing, how it is used by Orion.

If the main question was "Do I need configure RabbitMQ TCP port for nodes monitored by Agent?"

So then answer is no - it is used just for communication between services which runs on Orion poller servers.

Had a typo - "TCP/177991 (Agent comms to server 2008 R2)" should have read TCP/17791 .... The port # was the typo. Sorry for my fat fingers

Great thing about the agent, it allows you to decide what's best! Either (Orion) Server/Poller Initiated or Agent Initiated communication. Here's an older blog on how that works. Port information aside you can still determine from the blog how communication routes are demonstrated. SAM 6.2 Beta - Because Sometimes You Feel Like A Nut - Part 2

mbussey - Thanks for the reply. I'm aware of the ability to have monitored nodes with the SAM agent in stalled to either initiate comms back to the pollers or visa versa. My question is specifically aimed at the new port requirements. If these new ports are only for the SAM agent then I know the answer to my question. But there was no mention as to what exactly tcp/5671 (MQ Rabbit Messaging) is used for.

The RabbitMQ queue is used by Orion components to send event messages. SWIS on the main polling engine reads queue and forwards messages to subscribers. Other queues are used by subscribers to receive notifications forwarded by SWIS.

So whole mechanism is used just by Orion poller machnies and Orion Agents don't use it - because Orion Agents don't need for their jobs.

I tried to use this page to install an agent on a cloud instance. As it turns out, port 17790 is the correct port for server-initiated communication with the agent. I'm putting this here just in case someone follows this thread in the future.

Hey there! If ever needing a link to follow and bookmark for ports and Orion Agents, check these:

We also have these documented in the Port Requirements information: Port requirements for all SolarWinds products - SolarWinds Worldwide, LLC. Help and Support This is the replacement for the port requirements PDF. Thanks!

Very enlightening. That was indeed what I was looking for.
