About a strange question

kibana server is running on linux server normally and i can view data via chrome browser for kibana api.
but some days later i also open browser and input kibana api uri but the page is not found,then i logon linux server and input that 'ps aux|grep node' and i found it's process not exist.
this problem like above description is appear more times.

my kibana edition is 4.3.0

Is there anything in the KB logs?

where is the log folder?
i cann't found it
i download the 'kibana.tar.gz' package and install it.
now i accept your suggesttion to restart kb server like this 'nohup ./kibana >> kb.log &' and then i observe it‘s process for some days.

you can set the logging destination via the kibana.yml file in the config folder.

thanks,but i without rpm install and no this file.
