Hi,  
I am trying to pull Cloudwatch logs (specifically EC2 status) into Logstash. I can retrieve the status using AWS\_CLI, but the CloudWatch plugin throws the following error:

Pipeline\_id:main  
Plugin: \<LogStash::Inputs::CloudWatch access\_key\_id=\>"  
Error: uninitialized constant Aws::EC2  
Exception: NameError

My logstash\_config.conf file is:  
input {  
cloudwatch {  
namespace =\> "AWS/EC2"  
metrics =\> ["StatusCheckFailed"]  
filters =\> { "instance-id" =\> "i-ccc"}  
region =\> "us-east-1"  
access\_key\_id =\> "aaaa"  
secret\_access\_key =\> "bbb"  
}  
}

# filter {

#}  
output {  
stdout{  
codec =\> rubydebug  
}  
}

I am expecting to receive teh logs from Cloudwatch and print on stdout when I run logstash with this config file.

* * *

I do get the status via AWS\_CLI when I run \> aws ec2 describe-instance-status --instance-ids i-cccc  
as below

{  
"InstanceStatuses": [  
{  
"AvailabilityZone": "us-east-1c",  
"InstanceId": "i-cccc",  
"InstanceState": {  
"Code": 16,  
"Name": "running"  
},  
"InstanceStatus": {  
"Details": [  
{  
"Name": "reachability",  
"Status": "passed"  
}  
],  
"Status": "ok"  
},  
"SystemStatus": {  
"Details": [  
{  
"Name": "reachability",  
"Status": "passed"  
}  
],  
"Status": "ok"  
}  
}  
]  
}

Any pointers on what needs to be corrected please? Appreciate in advance.
