X-Pack Monitoring in Elasticsearch 5.6

Elastic Stack Elasticsearch
1

I am trying to install X-pack in standalone ES. I have configured
xpack.security.enabled: false
xpack.monitoring.enabled: true

in my elasticsearch.yml and kibana.yml and restarted both services.

But the monitoring option is not showing in Kibana interface.

Did you also install X-Pack into Kibana?

Yes, X-Pack is installed in kibana.
I have started kibana from /usr/share/kibana/bin/kibana, now I am able to access monitoring.
If I start kibana using command "sudo systemctl status kibana.service", monitoring option is not showing in kibana dashboard.
