So I’ve got a strange case where everything is “status green” yet Graylog randomly stop ingesting new messages from 1 specific input.
We have a cluster of 3 Kafka’s, every topic has set partition 3 replication 1 but there is this one input which has problems. I’ve discovered that on Input “Show details” it says that only one Graylog node has any I/O for that input, the rest has
Network IO: 0B
Every other input works like a charm, literally same idea: kafka topic with 3 partition and 1 replication. I wouldn’t mind that only one Graylog node ingests anything from that one input but it seems that randomly Graylog stops ingesting from it AT ALL and that’s problematic. Logstash logs 0 problems, so does Kafka.
