State metric for a Java Tomcat process always reporting as "sleeping"

Elastic Stack Beats
1

I'm running metricbeat oss 7.14.0 on Ubuntu 18.04.6 (Bionic Beaver) LTS and attempting to tell if my Java Tomcat is running or down however; the "state" of the process always reports as "sleeping" regardless of whether the process is running or has been stopped.

My Metricbeat config is the following:

########################## Metricbeat Configuration ###########################
# This file is a full configuration example documenting all non-deprecated
# options in comments. For a shorter configuration example, that contains only
# the most common options, please see metricbeat.yml in the same directory.

  # Configure the metric types that are included by these metricsets.
  cpu.metrics:  ["percentages","normalized_percentages"]  # The other available option is ticks.

output.elasticsearch:
  hosts: ["https://myelasticelastic:1000"]

  slow_start: true

I've started and stopped the process and it always reports as "sleeping". Is this a bug? Is there a better way to tell if the process is down or up?

Apart from a permissions issue, you can try the Tomcat module Tomcat module | Metricbeat Reference [7.15] | Elastic in the Xpack release, it's also free if that's your concern.

Is there a permission that needs to be set on the host in order for the "state" metric to be accurately calculated?
