Why sana?

Inspired heavily by Werner Vogels' frugal architect laws mentioned at the 2023 AWS re:Invent keynote, sana aims to provide tooling that fills in the gaps in the space of serverless observability. Here are some problem statements that sana tries to solve.

Detects how many functions in an account need to be migrated to the latest possible runtime.
Identifies how many DynamoDB tables were not configured with delete protection.
Eases reporting capabilities in CI/CD pipelines to enhance observability of build impact on your AWS accounts.
Provides the ability to observe the total health of an AWS account without leaving your VS Code/terminal.
And much more. StepFunctions, SQS, Event Bridge, S3, and CF commands are under development!"

Full Service Analysis

You can easily run full service analysis using the following commands:

sana lambda # Full Lambda Function Analysis

sana ddb # Full DynamoDB Table Analysis

Multi-command Prompts

You can also run multiple analysis in a single prompt using comma-separated commands.

# Runs full analysis for DynamoDB and Lambda
sana ddb,lambda

# Runs both average memory and timeout commands
sana lambda-avg-memory,lambda-avg-timeout

Global Flags

List of global flags that you can pass on all commands.

Authentication Modes

sana can authenticate against your AWS account by either using the default AWS CLI profile or by using named profiles. Take the example below

# Use default AWS profile in you dev machine.
sana lambda-runtime-distribution

# The same syntax works for CI/CD agents
# that relies on IAM roles
sana lambda-runtime-distribution

# If you need to target multiple accounts,
# You can use named profiles
sana lambda-runtime-distribution --profile foo

# Environment variable support is under development

Scanning Specific Regions

You can use the --region or -r flag to scan specific region(s) of interest.

# Single region syntax
sana ddb-count --region ap-southeast-1

# Multi-region syntax
sana ddb-count --region ap-southeast-1,us-east-1

# shorthand
sana ddb-count -r ap-southeast-1,us-east-1

Distribution Charts

For distribution queries, you can pass the -o chart flag to get the results printed in horizontal charts

# Lambda runtime distribution chart
sana lambda-runtime-distribution -o chart

# DynamoDB chart for delete protection status
sana ddb-delete-protection-distribution -r us-east-1  -o chart
