Find the cost of each resource in AWS - amazon-web-services

Question

I have a python script to get the cost of each service for the last month, but I want the cost for each resource using the tag mentioned for that resource. For example, I have got the cost for RDS service, am using two database instances, So I want to get the separate cost for two database instances . I have different tags for two database instances
TAGS:
First database instance --> Key: Name Value:rds1
Second database instance --> Key: Name Value:rds2
My output should be like , the tag of the resource and its cost
Example --> rds1 - 15$
rds2 - 10$
Can anyone help me to achieve this ?
I have attached the ouput I got for cost based on the service
Output for cost based on service

Make sure that the tags that you are listing are correct.
On top of this,
you could see all of the tags that have been created in your account by the user or it is AWS managed. here https://us-east-1.console.aws.amazon.com/billing/home#/tags.
with boto3 cost-explorer client, you could use this function list_cost_allocation_tags to get a list of cost allocation tags.
import boto3
start_date = '2022-07-01'
end_date = '2022-08-30'
client = boto3.client('ce')
tags_response = None
try:
tags_response = client.list_cost_allocation_tags(
Status='Inactive', # 'Active'|'Inactive',
# TagKeys=[
# 'Key',
# ],
Type='UserDefined', # 'AWSGenerated'|'UserDefined',
# NextToken='string',
# MaxResults=100,
)
except Exception as e:
print(e)
cost_allocation_tags = tags_response['CostAllocationTags']
print(cost_allocation_tags)
print("-"*5+' Input TagValues with comma separation '+"-"*5)
for cost_allocation_tag in cost_allocation_tags:
tag_key = cost_allocation_tag['TagKey']
tag_type = cost_allocation_tag['Type']
tag_status = cost_allocation_tag['Status']
tag_values = str(input(
f'TagKey: {tag_key}, Type: {tag_type}, Status: {tag_status} -> '))
if tag_values == "":
continue
tag_values_parsed = tag_values.strip().split(',')
if tag_values_parsed == []:
continue
cost_usage_response = None
try:
cost_usage_response = client.get_cost_and_usage(
TimePeriod={
'Start': start_date,
'End': end_date
},
Metrics=['AmortizedCost'],
Granularity='MONTHLY', # 'DAILY'|'MONTHLY'|'HOURLY',
Filter={
'Tags': {
'Key': tag_key,
'Values': tag_values_parsed,
'MatchOptions': [
'EQUALS' # 'EQUALS'|'ABSENT'|'STARTS_WITH'|'ENDS_WITH'|'CONTAINS'|'CASE_SENSITIVE'|'CASE_INSENSITIVE',
]
},
},
# GroupBy=[

# 'Key': 'string',

print(cost_usage_response)
