It looks like a service on EB did not restart when EB did. This is an issue to be handled by OTI.

I had apparently failed to enable the systemd service unit for node_exporter. I resolved this and started the service. This alert should clear momentarily, and should not happen again should EB get rebooted.

Issue, and alert, resolved. Closing issue.
