Boto cloudwatch in us-west-2 region not working #561

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

1. Run the following code: 

CLOUDMGMT01:~/bin$ python
Python 2.6.6 (r266:84292, Apr 11 2011, 15:50:32)
[GCC 4.4.4 20100726 (Red Hat 4.4.4-13)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import boto
>>> boto.Version
'2.0'
>>> import boto.ec2.cloudwatch
>>> cloudwatch =  boto.ec2.cloudwatch.connect_to_region("us-west-2")
>>> print cloudwatch
None
>>>

What is the expected output? What do you see instead?

List of CloudWatch metrics (actually anything != None)

What version of the product are you using? On what operating system?

Boto = 2.0 
OS = RHEL6

Please provide any additional information below.

We have a auto inventory script. It uses "boto.ec2.regions()" call to query all 
regions and then iterates over all of those regions. 

According to 
http://aws.typepad.com/aws/2011/11/now-open-us-west-portland-region.html the 
region support CloudWatch, so the API call should work. 

Actually other API calls work just fine (descript instances etc.)

Regards, 
Robert

Actually from looking at the code this is a design issue: 

https://github.com/boto/boto/blob/master/boto/ec2/cloudwatch/__init__.py

It has explicit region definition in it: 

RegionData = {
    'us-east-1' : 'monitoring.us-east-1.amazonaws.com',
    'us-west-1' : 'monitoring.us-west-1.amazonaws.com',
    'eu-west-1' : 'monitoring.eu-west-1.amazonaws.com',
    'ap-northeast-1' : 'monitoring.ap-northeast-1.amazonaws.com',
    'ap-southeast-1' : 'monitoring.ap-southeast-1.amazonaws.com'}

Same is true for: 
 - autoscaling
 - cloudwatch
 - elb

Programmatic Solution withour needing to query EC2 for regions first: 

  <pseudo>
  '%s' => 'FEATURE.%s.amazonaws.com' % (region.name,region.name)
  </pseudo>

The explicit list of regions is important because people occasionally want to 
query a service for a list of possible region endpoints.  You can do this 
programmatically with the EC2 service but no other service provides this so the 
hard-coded lists are there to mimic the capability.

I will probably refactor this code in the near future and will try to come up 
with a more flexible way of handling this.

The easy fix has been committed in 
https://github.com/boto/boto/commit/f4f4b9ec528f3af20221b9a18abe7b7c1bdbbb72
