Hi everyone,

regarding to my needs i defined a index template with PUT \_template API in kibana! on that template i set index pattern and specific index rollover alias.i send my logs from filebeat to logstash,,in logstash output i set elasticsearch and to my\_alias index.my elasticsearch cluster has 3 nodes and logstash is installed on that nodes.sometime when i restart my nodes it seems that rollovered index use a different template...in another word the template change to something else..  
is there anything wrong???

```auto
PUT /_template/my_template
{
    "order" : 0,
    "index_patterns" : ["my_index*"],
    "settings" : {
        "number_of_shards" : "5",
        "number_of_replicas" : "0",
        "index.lifecycle.name": "my_policy",
        "index.lifecycle.rollover_alias": "my_alias",
        "index.mapping.total_fields.limit": 5000,
        "codec": "best_compression"
        
    },
    "mappings" : {
      "date_detection": false,                     
      "properties" : {
        "timestamp" : {
          "format": "date_time||strict_date_time",   
            "type" : "date"
        },
        "@timestamp": {
          "format": "strict_date_optional_time",
           "type": "date"
        }
      }

Anything that matches your pattern there.  
Index temples to not just change after a reboot, something has to be changing it.
