I am configuring to read from s3 like below:  
input {  
s3 {  
access\_key\_id =\> "**"  
secret\_access\_key =\> "**\*\*\*\*\*\*\*\*"  
bucket =\> "fotolia-prod-logs"  
region =\> "eu-west-1"  
type =\> "syslog"  
delete =\> false  
}  
}

But get invalid config error from s3 part:  
fetched an invalid config {:config=\>"input {\n s3 {\n access\_key\_id =\> "ASIAIK7HB5C7TJIDRYXA"\n secret\_access\_key =\> "Uyr5uU307vUrQVWtRdqu5ykFIm+S+ttnlE7hn54L"\n bucket =\> "fotolia-prod-logs"\n region =\> "eu-west-1"\n type =\> "syslog"\n delete =\> false\n}\n}\n\n\nfilter {\n grok{\n break\_on\_match =\> false \n match =\> { "message" =\> "%{SYSLOGBASE} %{GREEDYDATA:message}" }\n overwrite =\> ["message"] \n} \n}\n\n\noutput {\n stdout { codec =\> rubydebug }\n}\n\n", :reason=\>"Expected one of #, ", ', } at line 3, column 1 (byte 17) after input {\n s3 {\n", :level=\>:error}

**Should I specify a prefix?** But the prefix are all different, like 2016/01/event\_log/generic.log; 2015/10/event\_log/generic.log. etc..

**If you just posted your secret access key I suggest you revoke it.**

The error message indicates a problem at the beginning of line 3. Perhaps you have some non-printable garbage character there?

> Should I specify a prefix?

The `prefix` option is not mandatory. Even if it were, its absence wouldn't result in this error message.
