Panic occure on running inputs.cloudwatch_metric_streams

1

Hello

I tried to collect data via inputs.cloudwatch_metric_streams. However, I couldn’t run Telegraf due to a panic error when I used this plugin.

I attempted to set the global address of my EC2 instance as the listening address. Should I use a different connection name? Can I use the DNS name of the EC2 instance’s connect endpoint for listening on port 443?

The debug message is shown below.

Note：
This message show version 1.29.0.
However I installed 1.30.3.

Any help is appreciated

Hello @yaaaaappie,
What do you get with

telegraf --version

For the cloudwatch_metric_streams plugin, you should configure the listening_address parameter in your telegraf.conf file.

[[inputs.cloudwatch_metric_streams]]
  listening_address = ":443"
  ## Use a specific DNS name if needed
  # listening_address = "ec2-xx-xx-xx-xx.compute-1.amazonaws.com:443"

Also for debugging you can do:

telegraf --config /etc/telegraf/telegraf.conf --debug

Or set

debug = true

In the agent portion of the config.
Just fyi for anyone else who might encounter this issue as well.
