We've been rolling out Defender for Endpoint on our AWS Linux instances (mix of Ubuntu and Amazon Linux 2). The onboarding went okay, but the agent seems to go silent randomly.
Some machines stop reporting to the security center for hours, then come back online in the portal without us doing anything. We followed the docs for manual installation. Has anyone else hit this? We're checking the mdatp logs, but it's not clearly crashing.
Is there a known issue with the agent's heartbeat on cloud instances, or a specific config we might have missed? We need consistent reporting for compliance. Any pointers on what to check next would be great.
