## Amazon Authentication
|
|
|
|
|
|
|
|
|
|
This plugin uses a credential chain for Authentication with the CloudWatch
|
|
|
|
|
API endpoint. In the following order the plugin will attempt to authenticate.
|
2016-05-25 11:30:39 +00:00
|
|
|
1. Assumed credentials via STS if `role_arn` attribute is specified (source credentials are evaluated from subsequent rules)
|
|
|
|
|
2. Explicit credentials from `access_key`, `secret_key`, and `token` attributes
|
|
|
|
|
3. Shared profile from `profile` attribute
|
|
|
|
|
4. [Environment Variables](https://github.com/aws/aws-sdk-go/wiki/configuring-sdk#environment-variables)
|
|
|
|
|
5. [Shared Credentials](https://github.com/aws/aws-sdk-go/wiki/configuring-sdk#shared-credentials-file)
|
|
|
|
|
6. [EC2 Instance Profile](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html)

## Config
|
|
|
|
|
|
|
|
|
|
For this output plugin to function correctly the following variables
|
|
|
|
|
must be configured.
|
|
|
|
|
|
|
|
|
|
* region
|
|
|
|
|
* namespace
|
|
|
|
|
|
|
|
|
|
### region
|
|
|
|
|
|
|
|
|
|
The region is the Amazon region that you wish to connect to.
|
|
|
|
|
Examples include but are not limited to:
|
|
|
|
|
* us-west-1
|
|
|
|
|
* us-west-2
|
|
|
|
|
* us-east-1
|
|
|
|
|
* ap-southeast-1
|
|
|
|
|
* ap-southeast-2
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
### write_statistics
|
|
|
|
|
|
|
|
|
|
If you have a large amount of metrics, you should consider to send statistic
|
|
|
|
|
values instead of raw metrics which could not only improve performance but
|
|
|
|
|
also save AWS API cost. If enable this flag, this plugin would parse the required
|
|
|
|
|
[CloudWatch statistic fields](https://docs.aws.amazon.com/sdk-for-go/api/service/cloudwatch/#StatisticSet)
|
|
|
|
|
(count, min, max, and sum) and send them to CloudWatch. You could use `basicstats`
|
|
|
|
|
aggregator to calculate those fields. If not all statistic fields are available,
|
2019-11-22 02:37:33 +00:00
|
|
|
all fields would still be sent as raw metrics.
|
|
|
|
|
|
|
|
|
|
## high_resolution_metrics
|
|
|
|
|
Enable high resolution metrics (1 second precision) instead of standard ones (60 seconds precision)
|
