Re: [EXTERNAL] Phoebus alarm server with Kafka 4.0

Late answer…

 

The setup example from https://github.com/ControlSystemStudio/phoebus/blob/master/app/alarm/Readme.md still refers to Kafka 3.6 with Zookeeper. The alarm server and the CS-Studio desktop still build with kafka version 3.6.1.

In a first test, however, that seems to work fine with a kafka 4 installation.

Rough diffs to the Readme.md mentioned above:

 

Get kafka_2.13-4.0.0 instead of 2.13-3.6.1

There is no config/zookeeper.properties

In config/server.properties, there is no zookeeper.connection.timeout.ms,

but you should still update the “log.dirs” to be something other than /tmp

and set “auto.create.topics.enable=false”.

 

Starting kafka is now different, see https://kafka.apache.org/documentation/#quickstart:

KAFKA_CLUSTER_ID="$(bin/kafka-storage.sh random-uuid)"

bin/kafka-storage.sh format --standalone -t $KAFKA_CLUSTER_ID -c config/server.properties

bin/kafka-server-start.sh config/server.properties

 

From then on, it’s the same:

sh create_alarm_topics.sh Accelerator

Start alarm server, start desktop, …

I have been using Kafka 3.7 on our alarm server and we are building a new one on Rocky9.  The (current)  Kafka 4.0.0 no longer uses zookeeper, so our configuration in the Kafka server.properties file is a bit different..  

 

Will the  Phoebus alarm server operate with Kafka 4, or should I stick with 3.x ?   I ask because I'm having some issues with Phoebus connecting with the alarm server.  The alarm log table does work for us.
