I upgrade elastic-stack from 5.6.8 to 6.6.2,there is no new messages into elasticsearch indices . When I just rollback logstash to 5.6.8 use the same configuration file than elk is work
I try to delete index template
DELETE /\_template/logstash
but not work
logstash.conf:
input {
kafka {
bootstrap\_servers =\> "node1:9092,node2:9092"
auto\_commit\_interval\_ms =\> "1000"
max\_poll\_records =\> "100"
session\_timeout\_ms =\> "30000"
request\_timeout\_ms =\> "40000"
group\_id =\> "logstash-662-2"
topics =\> ["webv2\_pre\_iis"]
decorate\_events =\> true
consumer\_threads =\> 5
codec =\> "json"
}
}
output {
if[kafka][topic] == "webv2\_pre\_iis" {
elasticsearch {
hosts =\> ["[http://node1:9200](http://node1:9200)","[http://node2:9200](http://node2:9200)","[http://node3:9200](http://node3:9200)"]
index =\> "webv2-pre-iis-%{+YYYYMMdd}"
}
}
}
