My architecture is

**`*Filebeat A*`** (remote) \> **Logstash A** (2 pipelines) \> **Elasticsearch A** \> **Kibana A**  
**`*Filebeat B*`** (remote) \> **Logstash A** (2 pipelines) \> **Elasticsearch A** \> **Kibana A**

Its for logs analysis.

say my logs format is `abc_logs-yyyy.mm.dd.log`

> My `Filebeats` are pushing logs to `Logstash` (I can see in `data/registry` file) but `Logstash` is **NOT** creating index for some of the log files.

say, `abc_logs-2019.11.02.log` is there in my log location and also `Filebeat` pushed it to `Logstash`. But I can't see any index created in elasticsearch.

Also, **one extra problem**.

> Even if the indexes are created, **NOT** all valid logs are getting parsed.

If I check the unparsed logs in grok debugger with the specified grok pattern, it is parsing perfectly.

Any solution for this problem?
