public final class LogsQueryAsyncClient

Provides an asynchronous service client for querying logs in the Azure Monitor Service.

The LogsQueryClient is an asynchronous client that provides methods to execute Kusto queries against Azure Monitor logs. It provides methods to query logs in a specific workspace, execute a batch of queries, and query logs for a specific Azure resource.

Getting Started

Authenticating and building instances of this client are handled by LogsQueryClientBuilder. This sample shows how to authenticate and build a LogQueryAsyncClient instance using LogQueryClientBuilder.

LogsQueryAsyncClient logsQueryAsyncClient = new LogsQueryClientBuilder()
         .credential(tokenCredential)
         .buildAsyncClient();

For more information on building and authenticating, see the LogsQueryClientBuilder documentation.

Client Usage

For more information on how to use this client, see the following method documentation:

• queryWorkspace(String workspaceId, String query, QueryTimeInterval timeInterval) - Query logs from a workspace.
• queryWorkspaceWithResponse(String workspaceId, String query, QueryTimeInterval timeInterval, LogsQueryOptions options) - Query logs from a workspace using query options with service response returned.
• queryBatch(LogsBatchQuery logsBatchQuery) - Execute a batch of logs queries.
• queryBatchWithResponse(LogsBatchQuery logsBatchQuery) - Execute a batch of logs queries with service response returned.
• queryResource(String resourceId, String query, QueryTimeInterval timeInterval) - Query logs for an Azure resource.
• queryResourceWithResponse(String resourceId, String query, QueryTimeInterval timeInterval, LogsQueryOptions options) - Query logs for an Azure resource using query options with service response returned.
