Nothing showing up for kafka_consumergroup_members

[ervikrant06]

Hello,

We are using the kafak-exporter (1.6.0) from a long time to monitoring our small 3 broker strimzi kafka cluster. It worked fine but from last 2-3 weeks we started noticing gap or completely missing metrics for the following series:

kafka_server_brokertopicmetrics_bytesin_total kafka_consumergroup_lag kafka_consumergroup_members

Updating the kafka exporter to latest version 1.7.0 doesn't help. Nothing shows up in the exporter logs.

Strimzi kafka version: 2.2.1

nothing changed at strimzi end. we are using following settings from the beginning. (it's a common endpoint for all kafka brokers)

        - --kafka.server=centrallogging-kafka.example.com:9094
        - --tls.enabled
        - --tls.ca-file=/etc/tls-certs/ca-file
        - --tls.cert-file=/etc/tls-certs/cert-file
        - --tls.key-file=/etc/tls-certs/key-file
        - --log.level=info
