This is typically handled by setting shards to a value that would get each shard to around 50G.

ILM is your future, it can rollover an index at size limit.

Can we do it like this for hourly logs  
output{  
elasticsearch{  
index =\> index\_name%{+YY.MM.dd.HH}  
}  
}

and if this is possible is there a way to do it for every 12 hours

Maybe it will be not ideal but you could do the following:  
parse the date from @timestamp, and check if the hour in the timestamp is having a certain value.

> #process the @timestamp

> 
> if [hour] \>= 12 {  
> mutate {  
> add\_field =\> {"index\_rotator"=\> "1"}  
> }  
> }  
> else {  
> mutate {  
> add\_field =\> {"index\_rotator"=\> "2"}  
> }  
> }
> 
> so you can have a predictable:
> 
> output{  
> elasticsearch{  
> index =\> index\_name%{+YY.MM.dd}-%{index\_rotator}  
> }

Or just use the \_ilm.  
It is much better and this is for what it was designed to.

BTW. What is your usecase? To store some log data? To query that data you are loading?

in output section  
output {  
elasticsearch {  
index =\> "resource-%{+YYYY.ww}"  
}  
}

or you can use xxxx.ww
