Если добавляю эту опцию к template который указываю в template\_name в output { elasticsearch { template\_name =\> "haproxy" } }, то она просто пропадает. И в GET /\_template/haproxy вижу: "aliases" : { "haproxy" : { } } Хотя в PUT /\_template/haproxy четко указал: "aliases" : { "haproxy" : { "is\_write\_index": true } } Как добавить эту опцию чтобы ILM не ругался на illegal\_argument\_exception: source alias [haproxy] does not point to a write index ---

Do any aliases exist? GET \_cat/indices/haproxy\* I think you assigned the alias to the template, the alias needs to be assigned to the index with one having "is\_write\_index": true. ---

Через template не получится (я открыл [https://github.com/elastic/elasticsearch/issues/52152](https://github.com/elastic/elasticsearch/issues/52152)), надо либо индекс либо алиас вручную создавать. ---

Но индексы каждый час создает logstash, назначать alias там возможности нет, есть только такой функционал: output { elasticsearch { ilm\_rollover\_alias =\> "custom" ilm\_pattern =\> "000001" ilm\_policy =\> "custom\_policy" } } У меня конфигурация такая: output { elasticsearch { id =\> "HAP Out" hosts =\> user =\> "" password =\> "" index =\> "haproxy-%{+YYYY.MM.dd-HH}" template\_name =\> "haproxy" } Что тогда в ilm\_pattern прописать? ---

No aliases. How can I assign alias to index created hourly by logstash? ---

ILM rollover phase will move the is\_write\_alias to the new index at rollover. To get started, the first index needs to exist and have is\_write\_alias: true. Use a [POST like this](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-aliases.html#aliases-write-index) to update the latest haproxy index with the is\_write\_alias. ``` POST /_aliases { "actions" : [ { "add" : { "index" : "haproxy-000001", "alias" : "haproxy", "is_write_index" : true } } } ``` If you don't have the initial ILM style index, you can create it as in the doc example ``` PUT datastream-000001 { "aliases": { "datastream": { "is_write_index": true } } } ``` It's a frequent confusion getting ILM working for the first time in more complex configurations, but once it works, you will see that there are many different ways to configure ILM. ---

Logstash creates index every hour, I posted my output section above, what exactly should I do? To output all data in one manually created index? I don't get it, sorry. ---

After creating the "haproxy-000001" index that has the is\_write\_alias: true, the output below should work. You will point to the alias, the index where is\_write\_alias is true will get the output. Only one is allowed and it will move to haproxy-000002 at rollover. ``` output { elasticsearch { id => "HAP Out" hosts => user => "" password => "" index => "haproxy" ilm_enabled => true ``` ---
