Cloud resource inventory collection for LogicMonitor licensing

LM Cloud Resource Inventory

A unified solution for collecting cloud resource counts across AWS, Azure, GCP, and OCI for LogicMonitor licensing purposes.

Overview

This tool collects resource inventory from cloud providers and calculates LogicMonitor license requirements by categorizing resources into:

• IaaS - Virtual machines and compute instances
• PaaS - Managed services, containers, serverless functions
• Non-Compute - Storage, networking, and other infrastructure resources

Quick Start

Installation

python3 -m pip install "lm-cloud-inventory[all]"

Or install from source:

git clone https://github.com/logicmonitor/lm-cloud-resource-inventory.git
cd lm-cloud-resource-inventory
python3 -m pip install ".[all]"

On Windows, use the Python 3 launcher so installation targets the same Python family used by the CLI:

py -3 -m pip install "lm-cloud-inventory[all]"

Basic Usage

# Run inventory and calculate licenses
lmci run -p aws -o aws_summary.csv
lmci run -p azure -o azure_summary.csv
lmci run -p gcp -o gcp_summary.csv
lmci run -p oci -o oci_summary.csv

# Any provider - with detailed output
lmci run -p aws -d -o detailed_report.csv

collect Command

Collect inventory only (saves JSON for later calculation).

lmci collect -p <provider> [options]

Option	Provider	Description
-p, --provider	All	Cloud provider (required)
-o, --output	All	Output JSON file (default: inventory.json)
--profile	AWS	AWS CLI profile name

-d, --detailed	Generate detailed CSV
--show-unmapped	List unmapped resource types

check-deps Command

Verify that required SDK packages are installed and importable. The command also prints the Python interpreter and CLI path, which helps identify packages installed into a different Python environment.

# Check all providers
lmci check-deps

# Check a specific provider
lmci check-deps -p azure

permissions Command

Show required permissions for each cloud provider.

lmci permissions -p aws
lmci permissions -p azure

Supported Cloud Providers

Provider	API Used	Performance
AWS	AWS Resource Explorer	~2-5 minutes
Azure	Azure Resource Graph	~1-2 minutes
GCP	Cloud Asset Inventory	~1-2 minutes
OCI	OCI Search Service	~1 minute

For a complete list of supported resources, see LogicMonitor Cloud Services Documentation.

AWS Resource Explorer Limitations

The following AWS services are not indexed by AWS Resource Explorer and will not be collected:

Service	Resource Type
CloudSearch	Domain
MediaConnect	Flow
MediaConvert	Queue
OpsWorks	Stack
Q Business	Application
QuickSight	Dashboard (dataset/datasource are supported)
Simple Workflow (SWF)	Domain
Application Migration Service	Source Server
ElasticTranscoder	Pipeline

If you have significant usage of these services, contact your LogicMonitor representative for manual inventory assistance.

Requirements

• Python 3.9+
• Cloud provider credentials configured via one of:
  • CLI tools (aws, az, gcloud, oci) - recommended for local use
  • Environment variables
  • Service account files
• Read-only permissions (see Permissions Documentation)

---

Credential Setup

Configure credentials for each cloud provider before running the inventory.

AWS Credentials

Option 1: AWS CLI (Recommended)

# Install AWS CLI and configure
aws configure

# Verify
aws sts get-caller-identity

Option 2: Environment Variables

export AWS_ACCESS_KEY_ID="your-access-key"
export AWS_SECRET_ACCESS_KEY="your-secret-key"
export AWS_DEFAULT_REGION="us-east-1"

Option 3: Named Profiles

# Use a specific profile
lmci run -p aws --profile production

Resources: AWS CLI Configuration

---

Azure Credentials

Option 1: Azure CLI (Recommended)

# Sign in
az login

# Verify
az account list --output table

Option 2: Service Principal

export AZURE_CLIENT_ID="appId"
export AZURE_CLIENT_SECRET="password"
export AZURE_TENANT_ID="tenant"

Resources: Azure CLI Authentication

---

GCP Credentials

Option 1: gcloud CLI (Recommended)

# Initialize and authenticate
gcloud init
gcloud auth application-default login

# Verify
gcloud config list

Option 2: Service Account Key

export GOOGLE_APPLICATION_CREDENTIALS="/path/to/service-account-key.json"

The tool will automatically extract the project_id from the service account JSON file.

Resources: GCP Application Default Credentials

---

OCI Credentials

Running in Cloud Shell

Each cloud provider offers a browser-based shell with credentials pre-configured - the fastest way to run the inventory tool.

Provider	Cloud Shell	Notes
AWS	AWS CloudShell	Python pre-installed, credentials automatic
Azure	Azure Cloud Shell	Python pre-installed, az authenticated
GCP	Google Cloud Shell	Python & gcloud pre-installed
OCI	OCI Cloud Shell	OCI CLI pre-installed

Detailed CSV (with -d flag)

Same as summary but saved to a separate _detailed.csv file.

Raw Inventory JSON

The _inventory.json file contains raw resource data for analysis:

[
  {
    "provider": "aws",
    "account_id": "123456789012",
    "region": "us-east-1",
    "resource_type": "ec2:instance",
    "count": 42,
    "timestamp": "2024-12-22T10:30:00Z"
  }
]

Troubleshooting

AWS: "Resource Explorer not enabled"

AWS Resource Explorer is required. Enable it in your account:

1. Go to AWS Resource Explorer Console
2. Enable Resource Explorer
3. Create an aggregator index for cross-region queries

AWS: "Access Denied"

# Verify credentials
aws sts get-caller-identity

Check Permissions Documentation for required IAM permissions.

Azure: "AuthorizationFailed"

# Verify login
az account show

Ensure you have the Reader role on the subscription(s).

GCP: "Permission denied"

# Verify auth
gcloud auth list

Ensure you have the roles/cloudasset.viewer role.

OCI: "NotAuthorizedOrNotFound"

# Verify config
cat ~/.oci/config

Ensure the policy allows: Allow group <group> to inspect all-resources in tenancy

General: "ModuleNotFoundError"

# Diagnose which dependencies are missing
lmci check-deps

# Install dependencies for a specific provider
python3 -m pip install "lm-cloud-inventory[aws]"
python3 -m pip install "lm-cloud-inventory[azure]"
python3 -m pip install "lm-cloud-inventory[gcp]"
python3 -m pip install "lm-cloud-inventory[oci]"

# Or install all providers at once
python3 -m pip install "lm-cloud-inventory[all]"

On Windows, replace python3 -m pip with py -3 -m pip.
