In kibana 4 0 2 there is no --log-file option  If I start kibana as a service with systemctl start kibana I find log in   var log messages

Kibana doesn t have a log file by default  but you can set it up using log file Kibana server property - https   www elastic co guide en kibana current kibana-server-properties html

It seems that you need to pass a flag  -l  --log-file   https   github com elastic kibana issues 3407  Usage  kibana  options   Kibana is an open source  Apache Licensed   browser based analytics and search dashboard for Elasticsearch   Options       -h  --help                 output usage information     -V  --version              output the version number     -e  --elasticsearch  lt uri gt   Elasticsearch instance     -c  --config  lt path gt         Path to the config file     -p  --port  lt port gt           The port to bind to     -q  --quiet                Turns off logging     -H  --host  lt host gt           The host to bind to     -l  --log-file  lt path gt       The file to log to     --plugins  lt path gt            Path to scan for plugins   If you use the init script to run as a service  maybe you will need to customize it

Kibana 4 logs to stdout by default  Here is an excerpt of the config kibana yml defaults     Enables you specify a file where Kibana stores log output    logging dest  stdout   So when invoking it with service  use the log capture method of that service  For example  on a Linux distribution using Systemd   systemctl  e g  RHEL 7      journalctl -u kibana service  One way may be to modify init scripts to use the --log-file option  if it still exists   but I think the proper solution is to properly configure your instance YAML file  For example  add this to your config kibana yml   logging dest   var log kibana log   Note that the Kibana process must be able to write to the file you specify  or the process will die without information  it can be quite confusing    As for the --log-file option  I think this is reserved for CLI operations  rather than automation
