Hi, Is it possible to give LS\_HEAP\_SIZE (-Xms and -Xmx) while starting logstash 1.4.2 or .15.2 like elasticsearch? instead of changing the [logstash.sh](http://logstash.sh) (We don't have permission on the logstash installation folder). Can we give the below command? logstash -d -Xms1024m -Xmx1024m agent -f logstash-test.conf Thanks, Thiru. ---

How did you install LS? ---

Hello Warkolm, Our admin installed logstash and elasticsearch where we don't have write permission. We used to run elasticsearch with HEAP\_SIZE (-Xms1024m -Xmx1024m) without editing the yml file. So, thought of asking like is there any way that we can give this HEAP\_SIZE when we start logstash without modifying the [logstash.sh](http://logstash.sh) where we don't have write permission. Thanks, Thiru. ---

Hello Warkolm, Do you still need more info for the way we installed LS? If yes, please let us know. If no, then could you please provide the options to run logstash with LS\_HEAP\_SIZE. This will be great help. Thanks, Thiru. ---

Try setting it by declaring a n environment variable called `LS_HEAP_SIZE`. ---

**Hello Warkolm,** I have declared an environment variable called LS\_HEAP\_SIZE and logstash is taking the value from this. Thanks for the input. Thanks, Thiru. ---
