kafka-manager-2.0.0.2 not displaying anything consumers tab

[af4007]

I've installed confluent-5.1.2 with Apache Kafka 2.1.x version, still we wont be able to see anything under 'Consumers' tabs and 'Consumers consuming from this topic' in Kafka-Manager.

We have already enabled below configurations:

1. Poll consumer information (Not recommended for large # of consumers if ZK is used for offsets tracking on older Kafka versions)
2. Enable Active OffsetCache (Not recommended for large # of consumers)

Appreciate your help here.

Thanks, Amol

By the way, is this project still "actively" supported? If not, I'll look towards something else.

@jeisea Came here by Google and sry I have to say this, but... ...that's not the spirit of open source software. If a project is only valuable for you if and as long others spent their time to maintain it, then please use something else. At least to me your statement sounds like a threat: Work in it or I will leave.

In case I got this wrong I apologize in advance.

We are using Kafka 2.2.0 Kafka Manager/CMAK 2.0.0.2 and had the same behavior

But I guess we figured it out... Is anybody of you using SASL/SSL?

We do and it turns out, that we need to set the security protocol and mechanism accordingly. In our case:

Also we changed a few SASL settings in conf/consumer.properties:

security.protocol=SASL_SSL
sasl.mechanism=PLAIN
key.deserializer=org.apache.kafka.common.serialization.ByteArrayDeserializer
value.deserializer=org.apache.kafka.common.serialization.ByteArrayDeserializer

I thought they should be overwritten be the config set in the UI, but for us it worked that way...

Hope this helps anybody
