List and check alias in elasticsearch

This post is older than a year. Consider some information might not be accurate anymore.

This post gives an example how to check an alias or aliases in elasticsearch with the REST-API.

As example we create an alias

curl -XPOST 'localhost:9200/_aliases' -d '
{
    "actions" : [
        { "add" : { "index" : "metrics*", "alias" : "stats" } }
    ]
}'

This checks for the index metrics which alias are available.

curl -XGET 'localhost:9200/metrics/_alias/*'

elasticsearch allwos you to use asterisks. If you want to check for all indices.
