Having strange issue within Monitoring:
We had node failure and during shards relocation we had zero event indexing in monitoring. However we've seen events entering pipeline and than indexed in ES cluster.
A bit info:
We have ES + Kibana 5.3 and Logstash 2.4 . All events are moving though Kafka and we can see offsets moving, so logstash getting data.
We are sending monitoring data in parallel to Datadog and seen indexing happening.
Half an hour after relocation completed we started to get indexing rates in kibana monitoring.
Thanks in advance
