# Azure Monitor Query SDK for Java

> **DEPRECATION NOTICE**: This package is deprecated in favor of:
> - `azure-monitor-query-logs` — For Log Analytics queries
> - `azure-monitor-query-metrics` — For metrics queries
>
> See migration guides: [Logs Migration](https://github.com/Azure/azure-sdk-for-java/blob/main/sdk/monitor/azure-monitor-query-logs/migration-guide.md) | [Metrics Migration](https://github.com/Azure/azure-sdk-for-java/blob/main/sdk/monitor/azure-monitor-query-metrics/migration-guide.md)

Client library for querying Azure Monitor Logs and Metrics.

## Installation

```xml
<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-monitor-query</artifactId>
    <version>1.5.9</version>
</dependency>
```

Or use Azure SDK BOM:

```xml
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.azure</groupId>
            <artifactId>azure-sdk-bom</artifactId>
            <version>{bom_version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

<dependencies>
    <dependency>
        <groupId>com.azure</groupId>
        <artifactId>azure-monitor-query</artifactId>
    </dependency>
</dependencies>
```

## Prerequisites

- Log Analytics workspace (for logs queries)
- Azure resource (for metrics queries)
- TokenCredential with appropriate permissions

## Environment Variables

```bash
LOG_ANALYTICS_WORKSPACE_ID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx  # Required for Log Analytics workspace queries
AZURE_RESOURCE_ID=/subscriptions/{sub}/resourceGroups/{rg}/providers/{provider}/{resource}  # Required for metrics queries against a resource
AZURE_TOKEN_CREDENTIALS=prod  # Required only if DefaultAzureCredential is used in production
```

## Client Creation

### LogsQueryClient (Sync)

```java
import com.azure.core.credential.TokenCredential;
import com.azure.identity.AzureIdentityEnvVars;
import com.azure.identity.DefaultAzureCredentialBuilder;
import com.azure.identity.ManagedIdentityCredentialBuilder;
import com.azure.monitor.query.LogsQueryClient;
import com.azure.monitor.query.LogsQueryClientBuilder;

// Local dev: DefaultAzureCredential. Production: set AZURE_TOKEN_CREDENTIALS=prod or AZURE_TOKEN_CREDENTIALS=<specific_credential>
TokenCredential credential = new DefaultAzureCredentialBuilder()
    .requireEnvVars(AzureIdentityEnvVars.AZURE_TOKEN_CREDENTIALS)
    .build();
// Or use a specific credential directly in production:
// See https://learn.microsoft.com/java/api/overview/azure/identity-readme?view=azure-java-stable#credential-classes
// TokenCredential credential = new ManagedIdentityCredentialBuilder().build();

LogsQueryClient logsClient = new LogsQueryClientBuilder()
    .credential(credential)
    .buildClient();
```

### LogsQueryAsyncClient

```java
import com.azure.monitor.query.LogsQueryAsyncClient;

LogsQueryAsyncClient logsAsyncClient = new LogsQueryClientBuilder()
    .credential(credential)
    .buildAsyncClient();
```

### MetricsQueryClient (Sync)

```java
import com.azure.monitor.query.MetricsQueryClient;
import com.azure.monitor.query.MetricsQueryClientBuilder;

MetricsQueryClient metricsClient = new MetricsQueryClientBuilder()
    .credential(credential)
    .buildClient();
```

### MetricsQueryAsyncClient

```java
import com.azure.monitor.query.MetricsQueryAsyncClient;

MetricsQueryAsyncClient metricsAsyncClient = new MetricsQueryClientBuilder()
    .credential(credential)
    .buildAsyncClient();
```

### Sovereign Cloud Configuration

```java
// Azure China Cloud - Logs
LogsQueryClient logsClient = new LogsQueryClientBuilder()
    .credential(credential)
