Error: no function clause matching Exporter:handle_info

Hello,

this seems due to:

• ex_aws #533
• hackney: #464

It should not affect the plugin itself so you shall not worry. I'll read through #464 and see if there's some recommended workaround to silence the noise.

I'm experiencing something similar with:

• RabbitMQ: 3.7.15
• Erlang: 22.0.3
• rabbitmq-cloudwatch-exporter: 0.2.0

Plugin crashes on all servers in turn, one by one.

Configuration

cluster_formation.peer_discovery_backend = rabbit_peer_discovery_aws
cluster_formation.aws.use_autoscaling_group = true
cluster_formation.node_cleanup.only_log_warning = false

cluster_partition_handling = pause_minority

disk_free_limit.relative = 2.0

vm_memory_high_watermark.relative = 0.4

cloudwatch_exporter.aws.region = "eu-west-1"
cloudwatch_exporter.metrics.1 = overview
cloudwatch_exporter.metrics.2 = vhost
cloudwatch_exporter.metrics.3 = node
cloudwatch_exporter.metrics.4 = exchange
cloudwatch_exporter.metrics.5 = queue
cloudwatch_exporter.metrics.6 = connection
cloudwatch_exporter.metrics.7 = channel
