MonitorDaemon-Reporter throttling_logger ERROR Error sending messages to firehose

[#1]

I have tried to deploy cloudera director on AWS EC2 instance to spin up a cluster. But it failed at bootstrap with below error. Please help.

The bootstrap fails when installing agent on nodes.

You may want to check whether CM is up and running properly. It's possible that CM is out of memory which can happen when the CM instance size is too small.
