Hi, can you try the version 3.0.0.6 which will contain https://github.com/yahoo/CMAK/pull/793 which added 2.3.1 support. Looks like 3.0.0.6 isn't out yet though

[poyyi]

i tried with 3.0.0.5 Master consumer group Lags are still not showing up... cmak..3.0.0.5 kafka version: 2.3.1 (upgraded from 0.11.0.0) server.properties inter.broker.protocol.version=2.3-IV1 log.message.format.version=0.11.0-IV2

connecting thru sasl_ssl and plain Tried multiple kafkaversion from drop down while setting it up with Addcluster option when i chose 2.3.1(which is kafka version), It shows this exception no cluster is configured..

Ask timed out on [ActorSelection[Anchor(akka://kafka-manager-system/), Path(/user/kafka-manager/PROD_SSAF_DADC_v231/kafka-state)]] after [2000 ms]. Message of type [kafka.manager.model.ActorModel$KSGetBrokers$] was sent by [Actor[akka://kafka-manager-system/user/kafka-manager/PROD_SSAF_DADC_v231#-1454503522]]. A typical reason for AskTimeoutException is that the recipient actor didn't send a reply.

But with 0.11.0.0 except of consumer lags (Lag unavailable ) everything shows up..

At the start up i see schema exception as

org.apache.kafka.common.protocol.types.SchemaException: Error reading field 'owned_partitions': java.nio.BufferUnderflowException at org.apache.kafka.common.protocol.types.Schema.read(Schema.java:110) at org.apache.kafka.clients.consumer.internals.ConsumerProtocol.deserializeSubscriptionV1(ConsumerProtocol.java:190)

And below timeout exception thrown repeatedly org.apache.kafka.common.errors.TimeoutException: Failed to get offsets by times in 30000ms 2020-09-15 21:23:52,779 - [ERROR] k.m.a.c.KafkaStateActor - KafkaTopicOffsetGetter exception

Also tried tweaking acls to give describe and read access Kmoffsetcache group...nothing worked Any Help is appreciated...

Thanks

I also encountered this error, Kafka-manager does not show offset, lag for all topics.

2022-04-18 02:56:16,458 - [ERROR] k.m.a.c.KafkaStateActor - KafkaTopicOffsetGetter exception
org.apache.kafka.common.errors.TimeoutException: Failed to get offsets by times in 30000ms

My environment:

kafka: v2.8.0
cmak: v3.0.0.4
number of topic partitions: 5k

It's hard to believe that it takes more than 30 seconds to get offset. So I try to get topic offsets one by one:

for consumer in `cat consumers`
do
    docker run -it --rm bitnami/kafka:2.8.0 /opt/bitnami/kafka/bin/kafka-consumer-groups.sh --bootstrap-server 10.0.0.1:9092 --group $consumer --describe &> $consumer
done

grep Error *

I found that several topics could not get offsets:

Error: Executing consumer group command failed due to org.apache.kafka.common.errors.TimeoutException: Call(callName=listOffsets on broker 1, deadlineMs=1650336669074, tries=1, nextAllowedTryMs=1650336669177) timedout at 1650336669077 after 1 attempt(s)
...
Caused by: org.apache.kafka.common.errors.DisconnectException: Cancelled listOffsets on broker 1 request with correlation id 5754 due to node 1 being disconnected

Then, I found similarities between these topics: a partition is blocked in the Under Replicated phase, so it cannot be connected by producers and consumers. Finally, I deleted these topics and recreated them. Kafka-manager now displays offsets for all topics.
