Aws cost and usage for all the instances - amazon-web-services

Question

I would like to get the usage cost report of each instance in my aws account form a period of time.
I'm able to get linked_account_id and service in the output but I need instance_id as well. Please help
import argparse
import boto3
import datetime
cd = boto3.client('ce', 'ap-south-1')
results = []
token = None
while True:
if token:
kwargs = {'NextPageToken': token}
else:
kwargs = {}
data = cd.get_cost_and_usage(
TimePeriod={'Start': '2019-01-01', 'End': '2019-06-30'},
Granularity='MONTHLY',
Metrics=['BlendedCost','UnblendedCost'],
GroupBy=[
{'Type': 'DIMENSION', 'Key': 'LINKED_ACCOUNT'},
{'Type': 'DIMENSION', 'Key': 'SERVICE'}
], **kwargs)
results += data['ResultsByTime']
token = data.get('NextPageToken')
if not token:
break
print('\t'.join(['Start_date', 'End_date', 'LinkedAccount', 'Service', 'blended_cost','unblended_cost', 'Unit', 'Estimated']))
for result_by_time in results:
for group in result_by_time['Groups']:
blended_cost = group['Metrics']['BlendedCost']['Amount']
unblended_cost = group['Metrics']['UnblendedCost']['Amount']
unit = group['Metrics']['UnblendedCost']['Unit']
print(result_by_time['TimePeriod']['Start'], '\t',
result_by_time['TimePeriod']['End'],'\t',
'\t'.join(group['Keys']), '\t',
blended_cost,'\t',
unblended_cost, '\t',
unit, '\t',
result_by_time['Estimated'])

Answer 1

As far as I know, Cost Explorer can't treat the usage per instance. There is a function Cost and Usage Reports which gives a detailed billing report by dump files. In this file, you can see the instance id.
It can also be connected to the AWS Athena. Once you did this, then directly query to the file on Athena.
Here is my presto example.
select
lineitem_resourceid,
sum(lineitem_unblendedcost) as unblended_cost,
sum(lineitem_blendedcost) as blended_cost
from
<table>
where
lineitem_productcode = 'AmazonEC2' and
product_operation like 'RunInstances%'
group by
lineitem_resourceid
The result is
lineitem_resourceid unblended_cost blended_cost
i-***************** 279.424 279.424
i-***************** 139.948 139.948
i-******** 68.198 68.198
i-***************** 3.848 3.848
i-***************** 0.013 0.013
where the resourceid containes the instance id. The amount of cost is summed for all usage in this month. For other type of product_operation, it will contains different resource ids.

You can add an individual tag to all instances (e.g. Id) and then group by that tag:
GroupBy=[
{
'Type': 'TAG',
'Key': 'Id'
},
],
