Client Creation

LogsQueryClient (Sync)

import com.azure.identity.DefaultAzureCredentialBuilder;
import com.azure.monitor.query.LogsQueryClient;
import com.azure.monitor.query.LogsQueryClientBuilder;

LogsQueryClient logsClient = new LogsQueryClientBuilder()
    .credential(new DefaultAzureCredentialBuilder().build())
    .buildClient();

LogsQueryAsyncClient

import com.azure.monitor.query.LogsQueryAsyncClient;

LogsQueryAsyncClient logsAsyncClient = new LogsQueryClientBuilder()
    .credential(new DefaultAzureCredentialBuilder().build())
    .buildAsyncClient();

MetricsQueryClient (Sync)

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

MetricsQueryClient metricsClient = new MetricsQueryClientBuilder()
    .credential(new DefaultAzureCredentialBuilder().build())
    .buildClient();

MetricsQueryAsyncClient

import com.azure.monitor.query.MetricsQueryAsyncClient;

MetricsQueryAsyncClient metricsAsyncClient = new MetricsQueryClientBuilder()
    .credential(new DefaultAzureCredentialBuilder().build())
    .buildAsyncClient();

Sovereign Cloud Configuration

// Azure China Cloud - Logs
LogsQueryClient logsClient = new LogsQueryClientBuilder()
    .credential(new DefaultAzureCredentialBuilder().build())
    .endpoint("https://api.loganalytics.azure.cn/v1")
    .buildClient();

// Azure China Cloud - Metrics
MetricsQueryClient metricsClient = new MetricsQueryClientBuilder()
    .credential(new DefaultAzureCredentialBuilder().build())
    .endpoint("https://management.chinacloudapi.cn")
    .buildClient();

Key Concepts

Logs Query Operations

Basic Query

import com.azure.monitor.query.models.LogsQueryResult;
import com.azure.monitor.query.models.LogsTableRow;
import com.azure.monitor.query.models.QueryTimeInterval;
import java.time.Duration;

LogsQueryResult result = logsClient.queryWorkspace(
    "{workspace-id}",
    "AzureActivity | summarize count() by ResourceGroup | top 10 by count_",
    new QueryTimeInterval(Duration.ofDays(7))
);

for (LogsTableRow row : result.getTable().getRows()) {
    System.out.println(row.getColumnValue("ResourceGroup") + ": " + row.getColumnValue("count_"));
}

Query by Resource ID

LogsQueryResult result = logsClient.queryResource(
    "{resource-id}",
    "AzureMetrics | where TimeGenerated > ago(1h)",
    new QueryTimeInterval(Duration.ofDays(1))
);

for (LogsTableRow row : result.getTable().getRows()) {
    System.out.println(row.getColumnValue("MetricName") + " " + row.getColumnValue("Average"));
}

Map Results to Custom Model

// Define model class
public class ActivityLog {
    private String resourceGroup;
    private String operationName;
    
    public String getResourceGroup() { return resourceGroup; }
    public String getOperationName() { return operationName; }
}

// Query with model mapping
List<ActivityLog> logs = logsClient.queryWorkspace(
