Can you share your Elasticsearch output configuration, and can you check if Elasticsearch is up and running properly?

{
"name" : "ip-10-1-2-ZxZZ.ec2.internal",
"cluster_name" : "Name of the cluster",
"cluster_uuid" : "XXXXXXXXXXXXXXXXZOO2Bg",
"version" : {
"number" : "7.1.0",
"build_flavor" : "default",
"build_type" : "rpm",

"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"

here i have shared this and i think it is running...

Elasticsearch{
hosts => ["http://XXXXXXXXXX197803029XXXXXXXXXXXXaws.com:9200"]
index => "Index_ name-%{+YYYY.MM}"
}
Elasticsearch{
hosts => ["http://ipaddressaws.com:9200"]
index => "IndexName--%{+YYYY.MM.dd}"
}
}

Could you use a recent version of the stack? 7.1 is so old!

but for now i have to implement in this version only

Why is that?

working in group and they are saying first we will impliment this task in this machine only the we will look to update version....

Did you check that Elasticsearch is available from the machine where Logstash is running?

10

Yes.. Elasticsearch is their on the same machine...

And also when I am running Logstash Logs I am getting ...
