Azure Storage Blob
Introduction
Azure Storage Blob is a scalable, durable, and secure object storage solution provided by Microsoft Azure for storing unstructured data such as documents, images, videos, backups, and logs.Azure Storage Blob Monitoring helps ensure the reliability, performance, and availability of your blob storage services. It enables you to track critical metrics such as read/write operations, latency, storage capacity, request rates, and error counts.
Getting Started
Compatibility
The Azure Storage Blob O11ySource supports Azure Storage Blob Services within standard lifecycle support.
Data Collection Method
Telemetry data for Azure Storage Blob comprises various metrics that monitor event processing performance, resource utilization, and operational health. Our internal agent, deployed within the vuSmartMaps environment, collects these metrics using a pull method.
Prerequisites
Dependent Configuration
To configure this O11ySource, create a 'credential' of type 'azure' under the 'Definition' tab.
Inputs for Configuring Data Source
- ** Resource Name**: Enter the Resource Name of Azure Storage
- Resource ID: A unique identifier for the Azure Storage.
- Credential: Client ID, Client Secret, Subscription ID and Tenant ID associated to the credential.
- Period (in seconds): Time interval for polling data from the Azure App Gateway. Period should be between 60 seconds – 3000 seconds.
- Account Name: Enter the Account Name of Azure Storage
- Account Key: Enter the Account Key of Azure Storage
Firewall Requirement
To collect data from this O11ySource, ensure the following ports are opened:
| Source IP | Destination IP | Destination Port | Protocol | Direction | 
|---|---|---|---|---|
| vuSmartMaps IP | Azure Monitor IP | 443* | TCP | Outbound | 
*Before providing the firewall requirements, please update the port based on the customer environment.
Configuring the Target
Health and performance metrics of Azure Storage Blob are collected through Azure Monitor service. Thus, Azure Monitor must be enabled in your Azure account. Azure Storage Blob Services should have available instances for which monitoring is enabled. To configure the access key, navigate to your Storage Account in the Azure portal, go to Security + Networking, select Access keys, and update the access key in the UI accordingly. An IAM role or user with the following permissions to access Azure Storage Blob metrics through Azure Monitor:
- Grant the Azure AD application, for which you've obtained the Client ID and Client Secret, the "Reader" role or a custom role specifically assigned with the Microsoft.Insights/metrics/read permission.
Configuration Steps
- Enablethe O11ySource.
- Select the sources tab and press the +button to add a new instance that has to be monitored.
- Provide the required configurations:
- *Resource Name
- *Period (in seconds)
- *Credential
- *Resource ID
- Click Saveto close the data source window.
