Goal

Query AWS data without API credentials. Don't wait for a response.

Examples

Please look at Billow in action in the Wiki and start contributing!

$ curl -sf billow.d.musta.ch/ec2 | jq '.[] | .az'
$ curl -sf "billow.d.musta.ch/ec2?q=$(urlencode 'key=="igor"')" |jq '.[]|.daysOld' | statistik
$ curl -sf 'billow.d.musta.ch/ec2?f=type' | jq -r '.[]|.type' | suc -r

API

The API is in a very early stage. Everything is subject to change.

Optional parameters

The ec2, dynamo, sqs and elasticache queries support following optional parameters:

  • q / query: OGNL expression used to filter. Example:
    • id>100&&readCapacityUnits>10
  • s / sort: OGNL expression used as a Comparable to sort (default to no ordering). Example:
    • s=itemCount
  • l / limit: maximum number of records to return. Example:
    • l=10
  • f / field: comma-separated list of fields to display(defaults to all). Examples:
    • f=tableName,tableStatus
    • f=tableName

Sample query: show readCapacityUnits and tableName of all tables sorted by readCapacity: /dynamo?s=readCapacityUnits&&f=readCapacityUnits,tableName&&l=3

Sample response:

[
  {
    tableName: "table_foo",
    readCapacityUnits: 1
  },
  {
    tableName: "table_bar",
    readCapacityUnits: 2
  },
  {
    tableName: "table_baz",
    readCapacityUnits: 3
  }
]

RDS Query

/rds/all

List all RDS resources.

DynamoDB Query

/dynamo

Search tables in DynamoDB with optional parameters.

Fields(readCapacityUnits and writeCapacityUnits are pulled out of provisionedThroughput which allows users to sort with these attributes):

{
  "tableName": "table_foo",
  "attributeDefinitions": "[{AttributeName: foo,AttributeType: S}]",
  "tableStatus": "ACTIVE",
  "keySchema": "[{AttributeName: foo,KeyType: HASH}]",

  "tableArn": "arn:aws:dynamodb:us-east-1:user_id:table/table_foo,
  "provisionedThroughput": "{NumberOfDecreasesToday: 0,ReadCapacityUnits: 1,
    WriteCapacityUnits: 1}"
}

SQS Query

/sqs

    autoMinorVersionUpgrade: true,
    securityGroups: "[]",
    replicationGroupId: null,
    snapshotRetentionLimit: null,
    snapshotWindow: null
}

Elasticsearch Query

/elasticsearch

Fields of elasticsearch domains:

IAM Query

/iam

List IAM user credentials.

Configuration

AWS

We strongly recommend creating a dedicated IAM user.

Here is the required User Policy:

{
  "Statement": [
    { "Action": [
        "ec2:DescribeRegions",
        "ec2:DescribeInstanceAttribute",
        "ec2:DescribeInstanceStatus",
        "ec2:DescribeInstances",
        "ec2:DescribeSecurityGroups",
        "rds:DescribeDBInstances",
        "iam:GetUser",
        "iam:ListUsers",
        "iam:ListAccessKeys"
      ],
      "Effect": "Allow",
      "Resource": [ "*" ]
    }
  ]
}

Local configuration

We use Typesafe's config. Look at the reference.conf resource for the available parameters. To get quickly started, pass the following parameters to the JVM: -Dbillow.aws.accessKeyId=HELLO -Dbillow.aws.secretKeyId=WoRld.

Note: For local development, ensure that you remove the profile prefix from profile names in ~/.aws/config and ~/.aws/credentials if you are using those. This is due to a mis-match in what the AWS Python SDK expects and what this version of the Java SDK expects. More details here.

Monitoring guide

We expose an admin port offering metrics and health checks. See http://127.0.0.1:8081/ by default.
