NetWorker: RabbitMQ Server and Erlang Versions Used By NetWorker

The RabbitMQ service is included with the NetWorker server, it serves as a message broker for connections from the NetWorker Management Console (NMC) server and NetWorker Web User Inter Interface (NWUI) to the NetWorker server.

Erlang is the programming language and runtime platform that RabbitMQ runs on. The Erlang Run-Time System (erts) is the Erlang virtual runtime environment that executes RabbitMQ. These components are embedded into the NetWorker server package and cannot be managed separately.

RabbitMQ Server Versions:

• NetWorker 19.10.0.0 uses 3.11.16
• NetWorker 19.12.0.0 uses 3.12.13
• NetWorker 19.12.0.3, 19.13.0.0 use 3.12.14
• NetWorker 19.12.0.4, 19.13.0.2 use 4.1.1
• NetWorker 19.14.0.1 is expected to use 4.1.8 (or later)
• NetWorker 19.15.0.0 is expected to use 4.2.9 (or later)

Erlang Runtime Versions:

• NetWorker 19.10.0.0 uses 13.2.2.0
• NetWorker 19.12.0.0 uses 13.2.2.7
• NetWorker 19.12.0.3, 19.13.0.0 use 13.2.2.15
• NetWorker 19.12.0.4, 19.13.0.2 uses 14.2.5.11
• NetWorker 19.14.0.1 is expected to use 14.2.5.13 (or newer)

How To Verify the RabbitMQ and Erlang Server Version:

Linux:

1. Open an elevated shell on the NetWorker server.
2. Check if NetWorker services are running: systemctl status networker or ps -ef | grep nsr
3. If NetWorker is running, check the rabbitmq-server process's command path: ps -ef | grep rabbitmq-server

[root@nsr ~]# ps -ef | grep rabbitmq-server

Alternatively, if NetWorker is not running, check the /opt/nsr folder. The rabbitmq-server folder path includes the RabbitMQ server version. This folder contains the erts subfolder which includes the Erlang version.

Windows

1. Open Windows Task Manager on the NetWorker server.
2. Go to the Details tab.
3. Ensure the Command line column is enabled and visible.
4. Look for epmd.exe. The Command Line path shows the rabbitmq-server folder path, which includes the RabbitMQ server version. The epmd (Erlang Port Mapper Daemon) is part of the Erlang runtime (erts). The erts path shows the Erlang version.

Alternatively, open Windows File Explorer and browse to your NetWorker install path, default: C:\Program Files\EMC NetWorker\nsr

The rabbitmq-server folder is in the ..\nsr folder path and includes the RabbitMQ version.

This rabbitmq-server-x.x.x folder contains the erts-version folder, which shows the Erlang version.
