Hi team,  
I am very new in Grok.  
I am struggling at this point. I cannot make a parser for below log file.  
The issue comes in [17/Aug/2021:16:46:33 +0700]. I cannot pass it.

```auto
192.168.40.100 - - [17/Aug/2021:16:46:33 +0700] "GET /favicon.ico HTTP/1.1" 404 493 "http://192.168.40.105/" "Mozilla/5.0 (iPhone; CPU iPhone OS 14_6 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.1.1 Mobile/15E148 Safari/604.1"

```

I have try to solve it but without success.

```auto
%{IP:ipaddress} - - \[%{TIMESTAMP_ISO8601:time} %{NOTSPACE:tz}\]%{GREEDYDATA:rest}

```

It is very appreciated to any helk or pointing out my bad.  
Thanks in advance!

Try just `%{COMBINEDAPACHELOG:message}`.

The reason why yours is not working is due to the timestamp (and maybe others, didn't go through it all). You can see the patterns for things such as `TIMESTAMP_ISO8601` [here](https://github.com/hpcugent/logstash-patterns/blob/master/files/grok-patterns) which you can see that pattern does not match your data. Your time matches the `HTTPDATE` pattern.

But when you do `COMBINEDAPACHELOG` it should parse it all since it's a common log type.

**WOWW! Brilliant!**

It works with COMBINEAPACHELOG perfectly.  
Thanks for the speedy response!
