Elastic Stack Logstash

I want to dynamic index from meassage nodename,but it's only show "%{[node_name]}" ,it's not my node_name. How can i config this?

filter {
grok {
match => {
"message"=>"#%{DATA:request_time}#%{DATA:node_name}#%{DATA:class_name}#%{DATA:log_level}#%{DATA:call_site}#%{DATA:line_number}#%{DATA:request_url}#%{DATA:request_method}#%{DATA:container_name}#%{DATA:action_name}#%{DATA:log_info}#%{DATA:exception}#%{DATA:ip}#%{DATA:form}#%{DATA:identity}" }
}
}

output{
elasticsearch{
hosts=>["127.0.0.1:9200"]
index=>"%{[node_name]}"

    }

}

Is the grok expression working so that the field is actually extracted? If you look at the data in Elasticsearch, do you see a _grokparsefailure tag? If not, can you show us what anindexed document looks like?

When i use this ,it was ok
output{
elasticsearch{
hosts=>["127.0.0.1:9200"]
index=>"defult"
}
}

output{
elasticsearch{
hosts=>["127.0.0.1:9200"]
