Metricbeat - Not creating any logfile

Question

I am trying to set up metric beat for my CentOS7 host. I have explictly mentioned the logfile location for the metricbeat and the logging level is debug, but I dont see a log file created. I can see the logs in journalctl. Please let me know why the logfile is not creating. Same setting works with filebeat and the log file gets created.

Metricbeat version:

[email protected]:/usr/share/metricbeat# metricbeat version
metricbeat version 7.2.0 (amd64), libbeat 7.2.0 [9ba65d864ca37cd32c25b980dbb4020975288fc0 built 2019-06-20 15:07:31 +0000 UTC]

Metricbeat config file: /etc/metricbeat/metricbeat.yml

metricbeat:
  config:
    modules:
      path: /etc/metricbeat/modules.d/*.yml
      reload.enabled: true
      reload.period: 10s

output.logstash:
  hosts: ['logstash.domain.com:5158']
  worker: 1
  compression_level: 3
  loadbalance: true
  ssl:
    certificate: /usr/share/metricbeat/metricbeat.crt
    key: /usr/share/metricbeat/metricbeat.key
    verification_mode: none

logging:
  level: debug
  to_files: true
  files:
    path: /var/myapp/log/metricbeat
    name: metricbeat.log
    rotateeverybytes: 10485760
    keepfiles: 7

Ideally it should create a file (metricbeat.log) in /var/myapp/log/metricbeat location, but I dont see any files getting created.

I dont see any thing in "/var/log/metricbeat" directory as well.

UPDATE: I tried with version 6.3 and 7.16. It works fine. Looks like some issue with 7.2
