SANnav configuration fails to start kafka

Hi All

I have a problem with my SANnav installation in Stor2rrd 7.90, the Kafka consumer deamon is not running.

System info:  Ubuntu 22.04.4 LTS (GNU/Linux 5.15.0-112-generic x86_64)

My (from the GUI) SANnav host connection test looks like this:

STOR2RRD version: 7.90 (free)

API host network connection: OK

TCP connection to 10.x.x.y:443 is OK.

STOR2RRD version: 7.90 (free)

API host network connection:

KAFKA network connection (usually on the same machine as STOR2RRD): Warning

TCP connection to 10.x.x.x:8081 has failed! Open it on the firewall.

TCP connection to 10.x.x.x:9092 has failed! Open it on the firewall.

Crontab test: OK

API authorization: OK

Switches : 80

Fabrics : 10

Kafka data test: NOK

Kafka consumer daemon is not running (sannavperf.py 10.x.x.x).

Try this connection test again after 10 minutes.

---------------------------------------------------------------

The log looks like this:

stor2rrd:/home/stor2rrd/stor2rrd$ sudo cat logs/error.log-kafka-consumer-10.x.x.x

Traceback (most recent call last):

 File "/home/stor2rrd/stor2rrd/bin/sannavperf.py", line 2, in <module>

   from kafkian import Consumer

ModuleNotFoundError: No module named 'kafkian'

I've used the Ubuntu / Debian installation dokumentation:

apt install python3-pip

apt install python3-requests

apt install python3-dev

apt install librdkafka-dev
