Hi, I have logs with similar timestamp out of order: I understand logstash does not preserve creation order.  
I read that using dissect filter together with grok could solve the issue but can't find any examples.  
This is my current setup:

```auto
`if "GW" in [log][file][path] {`
` mutate { add_tag => "devices" }`
` date {`
` match => ["datetime" ,"yyyy-MM-dd HH:mm:ss.SSSSSS"]`
` timezone => "GMT"`
` target => "@timestamp"`
` }`

```
