Creating index dynamically in ES

Wondering if i could create index based on the JSON fields dynamically in
Elasticsearch when Logstash forwards a JSON formatted message to
Elasticsearch.

For example:

Logstash forwards message in the following format:

"MONTH": [
[
"Jan"
]
],
"MONTHDAY": [
[
"9"
]
]

I wanted to create index based on MONTH and MONTHDAY in Elasticsearch. Could someone please help me out?

You can specify the index name in the elasticsearch output:

http://logstash.net/docs/1.3.3/outputs/elasticsearch#index

For example, let's say I have a field named clientip, I can make indexes
named ls-clientip by specifying something like this:

output {
elasticsearch {
host => "localhost"
index => "ls-%{clientip}"
}
}

Thanks for the response.

I was not looking for this one.

What i meant was could i create indexes based on MONTH and MONTHDAY
respectively at the same time.

Keep in mind that ES index names can only be all lowercase (so you have to
lowercase the values first in LS). Try something like this (after
lowercasing the values first)?

output {
elasticsearch {
host => "localhost"
index => "%{MONTH}-%{MONTHDAY}"
}
}

Hello Binh Ly,
How or where do you declare the variables such as %{clientip}?
Thanks

They are fields in the message, often populated by a 'grok' filter.

Note that not all strings in Logstash configuration files support
%{variablename} interpolation. Where you can use such references
is unfortunately underdocumented.
