Elastic Agent Doesn't Seem to Restart ElasticEndpoint Security Service

Hi All,

I was recently doing some troubleshooting with a degraded Elastic Agent install, and I noticed that when you restart the elastic-agent it doesn't actually cause a restart of the Elastic Endpoint service, therefore leaving it in a degraded state. I was wonder if any else has come across this issue, and found a solution for it.

Elastic Agent version: 7.17.0
Install Method: .tar

Elastic Agent systemctl status: sudo systemctl status elastic-agent

Because the ElasticEndpoint service never gets restarted the Elastic Agent can never go into a healthy state.

Manually restarting the ElasticEndpoint service: sudo systemctl restart ElasticEndpoint

Appears to fix this issue: sudo /opt/Elastic/Agent/elastic-agent status

Given that the ElasticEndpoint service is added as part of the Elastic Agent itself, I would've expected restarting the Elastic Agent itself to also restart ElasticEndpoint service.
