Package version:

@azure/monitor-query

Deprecated ⚠️: This package has been deprecated and is no longer under active development. Please migrate to the following packages:

New features and non-security bug fixes will be added to the replacement libraries listed above.

The Azure Monitor Query client library is used to execute read-only queries against Azure Monitor's two data platforms:

  • Logs - Collects and organizes log and performance data from monitored resources. Data from different sources such as platform logs from Azure services, log and performance data from virtual machines agents, and usage and performance data from apps can be consolidated into a single Azure Log Analytics workspace. The various data types can be analyzed together using the Kusto Query Language.
  • Metrics - Collects numeric data from monitored resources into a time series database. Metrics are numerical values that are collected at regular intervals and describe some aspect of a system at a particular time. Metrics are lightweight and capable of supporting near real-time scenarios, making them useful for alerting and fast detection of issues.

Prerequisites

Install the package

Install the Azure Monitor Query client library for JavaScript with npm:

npm install --save @azure/monitor-query

Create the client

An authenticated client is required to query Logs or Metrics. To authenticate, the following example uses DefaultAzureCredential from the @azure/identity package.

import { DefaultAzureCredential } from "@azure/identity";
import { LogsQueryClient, MetricsQueryClient, MetricsClient } from "@azure/monitor-query";

const credential = new DefaultAzureCredential();

// Create a LogsQueryClient
const logsQueryClient = new LogsQueryClient(credential);

// Create a MetricsQueryClient
const metricsQueryClient = new MetricsQueryClient(credential);

// Create a MetricsClient
const endpoint = " https://<endpoint>.monitor.azure.com/";
const metricsClient = new MetricsClient(endpoint, credential);

Configure client for Azure sovereign cloud

By default, the library's clients are configured to use the Azure Public Cloud. To use a sovereign cloud instead, provide the correct endpoint and audience value when instantiating a client. For example:

import { DefaultAzureCredential } from "@azure/identity";
import { LogsQueryClient, MetricsQueryClient, MetricsClient } from "@azure/monitor-query";

const credential = new DefaultAzureCredential();

// Create a LogsQueryClient
const logsQueryClient: LogsQueryClient = new LogsQueryClient(credential, {
  endpoint: "https://api.loganalytics.azure.cn/v1",
  audience: "https://api.loganalytics.azure.cn/.default",
});

// Create a MetricsQueryClient
const metricsQueryClient: MetricsQueryClient = new MetricsQueryClient(credential, {
  endpoint: "https://management.chinacloudapi.cn",
  audience: "https://monitor.azure.cn/.default",
});

// Create a MetricsClient
const endpoint = " https://<endpoint>.monitor.azure.cn/";
const metricsClient = new MetricsClient(endpoint, credential, {
  audience: "https://monitor.azure.cn/.default",
});

Note: Currently, MetricsQueryClient uses the Azure Resource Manager (ARM) endpoint for querying metrics. You need the corresponding management endpoint for your cloud when using this client. This detail is subject to change in the future.

Execute the query

For examples of Logs and Metrics queries, see the Examples section.

Key concepts

Logs query rate limits and throttling

The Log Analytics service applies throttling when the request rate is too high. Limits, such as the maximum number of rows returned, are also applied on the Kusto queries. For more information, see Query API.

Metrics data structure

Each set of metric values is a time series with the following characteristics:

  • The time the value was collected
  • The resource associated with the value
  • A namespace that acts like a category for the metric
  • A metric name
  • The value itself
  • Some metrics have multiple dimensions as described in multi-dimensional metrics. Custom metrics can have up to 10 dimensions.

Examples

Logs query

The LogsQueryClient can be used to query a Log Analytics workspace using the Kusto Query Language. The timespan.duration can be specified as a string in an ISO 8601 duration format. You can use the Durations constants provided for some commonly used ISO 8601 durations.

You can query logs by Log Analytics workspace ID or Azure resource ID. The result is returned as a table with a collection of rows.

Workspace-centric logs query

To query by workspace ID, use the LogsQueryClient.queryWorkspace method:

import { LogsQueryClient, Durations, LogsQueryResultStatus } from "@azure/monitor-query";
import { DefaultAzureCredential } from "@azure/identity";

const azureLogAnalyticsWorkspaceId = "<workspace_id>";
const logsQueryClient = new LogsQueryClient(new DefaultAzureCredential());

const kustoQuery = "AppEvents | limit 1";
const result = await logsQueryClient.queryWorkspace(azureLogAnalyticsWorkspaceId, kustoQuery, {
  duration: Durations.twentyFourHours,
});

if (result.status === LogsQueryResultStatus.Success) {
  const tablesFromResult = result.tables;

  if (tablesFromResult.length === 0) {
    console.log(`No results for query '${kustoQuery}'`);
    return;
  }
  console.log(`This query has returned table(s) - `);
  processTables(tablesFromResult);
} else {
  console.log(`Error processing the query '${kustoQuery}' - ${result.partialError}`);
  if (result.partialTables.length > 0) {
    console.log(`This query has also returned partial data in the following table(s) - `);
    processTables(result.partialTables);
  }
}

function processTables(tablesFromResult) {
  for (const table of tablesFromResult) {
    const columnHeaderString = table.columnDescriptors
      .map((column) => `${column.name}(${column.type}) `)
      .join("| ");
    console.log("| " + columnHeaderString);
    for (const row of table.rows) {
      const columnValuesString = row.map((columnValue) => `'${columnValue}' `).join("| ");
      console.log("| " + columnValuesString);
    }
  }
}

Resource-centric logs query

The following example demonstrates how to query logs directly from an Azure resource. Here, the queryResource method is used and an Azure resource ID is passed in. For example, /subscriptions/{subscription-id}/resourceGroups/{resource-group-name}/providers/{resource-provider}/{resource-type}/{resource-name}.

To find the resource ID:

  1. Navigate to your resource's page in the Azure portal.
  2. From the Overview blade, select the JSON View link.
  3. In the resulting JSON, copy the value of the id property.
import { DefaultAzureCredential } from "@azure/identity";
import { LogsQueryClient, Durations, LogsQueryResultStatus } from "@azure/monitor-query";

const logsResourceId = "<the Resource Id for your logs resource>";

const tokenCredential = new DefaultAzureCredential();
const logsQueryClient = new LogsQueryClient(tokenCredential);

const kustoQuery = `MyTable_CL | summarize count()`;

console.log(`Running '${kustoQuery}' over the last One Hour`);
const queryLogsOptions = {
  // explicitly control the amount of time the server can spend processing the query.
  serverTimeoutInSeconds: 600, // sets the timeout to 10 minutes
  // optionally enable returning additional statistics about the query's execution.
  // (by default, this is off)
  includeQueryStatistics: true,
};

const result = await logsQueryClient.queryResource(
  logsResourceId,
  kustoQuery,
  { duration: Durations.sevenDays },
  queryLogsOptions,
);

const executionTime = (result as any)?.statistics?.query?.executionTime;

console.log(
  `Results for query '${kustoQuery}', execution time: ${executionTime == null ? "unknown" : executionTime}`,
);

if (result.status === LogsQueryResultStatus.Success) {
  const tablesFromResult = result.tables;

  if (tablesFromResult.length === 0) {
    console.log(`No results for query '${kustoQuery}'`);
    return;
  }
  console.log(`This query has returned table(s) - `);
  processTables(tablesFromResult);
} else {
  console.log(`Error processing the query '${kustoQuery}' - ${result.partialError}`);
  if (result.partialTables.length > 0) {
    console.log(`This query has also returned partial data in the following table(s) - `);
    processTables(result.partialTables);
  }
}

function processTables(tablesFromResult) {
  for (const table of tablesFromResult) {
    const columnHeaderString = table.columnDescriptors
      .map((column) => `${column.name}(${column.type}) `)
      .join("| ");
    console.log("| " + columnHeaderString);

    for (const row of table.rows) {
      const columnValuesString = row.map((columnValue) => `'${columnValue}' `).join("| ");
      console.log("| " + columnValuesString);
    }
  }
}

Handle logs query response

The queryWorkspace function of LogsQueryClient returns a LogsQueryResult object. The object type can be LogsQuerySuccessfulResult or LogsQueryPartialResult. Here's a hierarchy of the response:

LogsQuerySuccessfulResult
|---statistics
|---visualization
|---status ("Success")
|---tables (list of `LogsTable` objects)
    |---name
    |---rows
    |---columnDescriptors (list of `LogsColumn` objects)
        |---name
        |---type

LogsQueryPartialResult
|---statistics
|---visualization
|---status ("PartialFailure")
|---partialError
    |--name
    |--code
    |--message
    |--stack
|---partialTables (list of `LogsTable` objects)
    |---name
    |---rows
    |---columnDescriptors (list of `LogsColumn` objects)
        |---name
        |---type

For example, to handle a response with tables:

function processTables(tablesFromResult) {
  for (const table of tablesFromResult) {
    const columnHeaderString = table.columnDescriptors
      .map((column) => `${column.name}(${column.type}) `)
      .join("| ");
    console.log("| " + columnHeaderString);

    for (const row of table.rows) {
      const columnValuesString = row.map((columnValue) => `'${columnValue}' `).join("| ");
      console.log("| " + columnValuesString);
    }
  }
}

A full sample can be found here.

Batch logs query

The following example demonstrates sending multiple queries at the same time using the batch query API. The queries can be represented as a list of BatchQuery objects.

import { DefaultAzureCredential } from "@azure/identity";
import { LogsQueryClient, LogsQueryResultStatus } from "@azure/monitor-query";

const monitorWorkspaceId = "<workspace_id>";

const tokenCredential = new DefaultAzureCredential();
const logsQueryClient = new LogsQueryClient(tokenCredential);

const kqlQuery = "AppEvents | project TimeGenerated, Name, AppRoleInstance | limit 1";
const queriesBatch = [
  {
    workspaceId: monitorWorkspaceId,
    query: kqlQuery,
    timespan: { duration: "P1D" },
  },
  {
    workspaceId: monitorWorkspaceId,
    query: "AzureActivity | summarize count()",
    timespan: { duration: "PT1H" },
  },
  {
    workspaceId: monitorWorkspaceId,
    query:
      "AppRequests | take 10 | summarize avgRequestDuration=avg(DurationMs) by bin(TimeGenerated, 10m), _ResourceId",
    timespan: { duration: "PT1H" },
  },
  {
    workspaceId: monitorWorkspaceId,
    query: "AppRequests | take 2",
    timespan: { duration: "PT1H" },
    includeQueryStatistics: true,
  },
];

const result = await logsQueryClient.queryBatch(queriesBatch);

if (result == null) {
  throw new Error("No response for query");
}

let i = 0;
for (const response of result) {
  console.log(`Results for query with query: ${queriesBatch[i]}`);
  if (response.status === LogsQueryResultStatus.Success) {
    console.log(
      `Printing results from query '${queriesBatch[i].query}' for '${queriesBatch[i].timespan}'`,
    );
    processTables(response.tables);
  } else if (response.status === LogsQueryResultStatus.PartialFailure) {
    console.log(
      `Printing partial results from query '${queriesBatch[i].query}' for '${queriesBatch[i].timespan}'`,
    );
    processTables(response.partialTables);
    console.log(
      ` Query had errors:${response.partialError.message} with code ${response.partialError.code}`,
    );
  } else {
    console.log(`Printing errors from query '${queriesBatch[i].query}'`);
    console.log(` Query had errors:${response.message} with code ${response.code}`);
  }
  // next query
  i++;
}

function processTables(tablesFromResult) {
  for (const table of tablesFromResult) {
    const columnHeaderString = table.columnDescriptors
      .map((column) => `${column.name}(${column.type}) `)
      .join("| ");
    console.log("| " + columnHeaderString);

    for (const row of table.rows) {
      const columnValuesString = row.map((columnValue) => `'${columnValue}' `).join("| ");
      console.log("| " + columnValuesString);
    }
  }
}

Handle logs batch query response

The queryBatch function of LogsQueryClient returns a LogsQueryBatchResult object. LogsQueryBatchResult contains a list of objects with the following possible types:

  • LogsQueryPartialResult
  • LogsQuerySuccessfulResult
  • LogsQueryError

Here's a hierarchy of the response:

LogsQuerySuccessfulResult
|---statistics
|---visualization
|---status ("Success")
|---tables (list of `LogsTable` objects)
    |---name
    |---rows
    |---columnDescriptors (list of `LogsColumn` objects)
        |---name
        |---type

LogsQueryPartialResult
|---statistics
|---visualization
|---status ("PartialFailure")
|---partialError
    |--name
    |--code
    |--message
    |--stack
|---partialTables (list of `LogsTable` objects)
    |---name
    |---rows
    |---columnDescriptors (list of `LogsColumn` objects)
        |---name
        |---type

LogsQueryError
|--name
|--code
|--message
|--stack
|--status ("Failure")

For example, the following code handles a batch logs query response:

import { LogsQueryResultStatus } from "@azure/monitor-query";

async function processBatchResult(result, queriesBatch) {
  let i = 0;
  for (const response of result) {
    console.log(`Results for query with query: ${queriesBatch[i]}`);
    if (response.status === LogsQueryResultStatus.Success) {
      console.log(
        `Printing results from query '${queriesBatch[i].query}' for '${queriesBatch[i].timespan}'`,
      );
      processTables(response.tables);
    } else if (response.status === LogsQueryResultStatus.PartialFailure) {
      console.log(
        `Printing partial results from query '${queriesBatch[i].query}' for '${queriesBatch[i].timespan}'`,
      );
      processTables(response.partialTables);
      console.log(
        ` Query had errors:${response.partialError.message} with code ${response.partialError.code}`,
      );
    } else {
      console.log(`Printing errors from query '${queriesBatch[i].query}'`);
      console.log(` Query had errors:${response.message} with code ${response.code}`);
    }
    // next query
    i++;
  }
}

function processTables(tablesFromResult) {
  for (const table of tablesFromResult) {
    const columnHeaderString = table.columnDescriptors
      .map((column) => `${column.name}(${column.type}) `)
      .join("| ");
    console.log("| " + columnHeaderString);

    for (const row of table.rows) {
      const columnValuesString = row.map((columnValue) => `'${columnValue}' `).join("| ");
      console.log("| " + columnValuesString);
    }
  }
}

A full sample can be found here.

Advanced logs query scenarios

Set logs query timeout

Some logs queries take longer than 3 minutes to execute. The default server timeout is 3 minutes. You can increase the server timeout to a maximum of 10 minutes. In the following example, the LogsQueryOptions object's serverTimeoutInSeconds property is used to increase the server timeout to 10 minutes:

import { DefaultAzureCredential } from "@azure/identity";
import { LogsQueryClient, Durations } from "@azure/monitor-query";

const azureLogAnalyticsWorkspaceId = "<workspace_id>";

const tokenCredential = new DefaultAzureCredential();
const logsQueryClient = new LogsQueryClient(tokenCredential);

const kqlQuery = "AppEvents | project TimeGenerated, Name, AppRoleInstance | limit 1";

// setting optional parameters
const queryLogsOptions = {
  // explicitly control the amount of time the server can spend processing the query.
  serverTimeoutInSeconds: 600, // 600 seconds = 10 minutes
};

const result = await logsQueryClient.queryWorkspace(
  azureLogAnalyticsWorkspaceId,
  kqlQuery,
  { duration: Durations.twentyFourHours },
  queryLogsOptions,
);

const status = result.status;

Query multiple workspaces

The same logs query can be executed across multiple Log Analytics workspaces. In addition to the Kusto query, the following parameters are required:

  • workspaceId - The first (primary) workspace ID.
  • additionalWorkspaces - A list of workspaces, excluding the workspace provided in the workspaceId parameter. The parameter's list items can consist of the following identifier formats:
    • Qualified workspace names
    • Workspace IDs
    • Azure resource IDs

For example, the following query executes in three workspaces:

import { DefaultAzureCredential } from "@azure/identity";
import { LogsQueryClient, Durations } from "@azure/monitor-query";

const azureLogAnalyticsWorkspaceId = "<workspace_id>";

const tokenCredential = new DefaultAzureCredential();
const logsQueryClient = new LogsQueryClient(tokenCredential);

const kqlQuery = "AppEvents | project TimeGenerated, Name, AppRoleInstance | limit 1";

// setting optional parameters
const queryLogsOptions = {
  additionalWorkspaces: ["<workspace2>", "<workspace3>"],
};

const result = await logsQueryClient.queryWorkspace(
  azureLogAnalyticsWorkspaceId,
  kqlQuery,
  { duration: Durations.twentyFourHours },
  queryLogsOptions,
);

const status = result.status;

To view the results for each workspace, use the TenantId column to either order the results or filter them in the Kusto query.

Order results by TenantId

AppEvents | order by TenantId

Filter results by TenantId

AppEvents | filter TenantId == "<workspace2>"

A full sample can be found here.

Include statistics

To get logs query execution statistics, such as CPU and memory consumption:

  1. Set the LogsQueryOptions.includeQueryStatistics property to true.
  2. Access the statistics field inside the LogsQueryResult object.

The following example prints the query execution time:

import { LogsQueryClient, Durations } from "@azure/monitor-query";
import { DefaultAzureCredential } from "@azure/identity";

const monitorWorkspaceId = "<workspace_id>";
const logsQueryClient = new LogsQueryClient(new DefaultAzureCredential());
const kustoQuery = "AzureActivity | top 10 by TimeGenerated";

const result = await logsQueryClient.queryWorkspace(
  monitorWorkspaceId,
  kustoQuery,
  { duration: Durations.oneDay },
  {
    includeQueryStatistics: true,
  },
);

const executionTime = (result as any)?.statistics?.query?.executionTime;

console.log(
  `Results for query '${kustoQuery}', execution time: ${executionTime == null ? "unknown" : executionTime}`,
);

Because the structure of the statistics payload varies by query, a Record<string, unknown> return type is used. It contains the raw JSON response. The statistics are found within the query property of the JSON. For example:

{
  "query": {
    "executionTime": 0.0156478,
    "resourceUsage": {...},
    "inputDatasetStatistics": {...},
    "datasetStatistics": [{...}]
  }
}

Include visualization

To get visualization data for logs queries using the render operator:

  1. Set the LogsQueryOptions.includeVisualization property to true.
  2. Access the visualization field inside the LogsQueryResult object.

For example:

import { LogsQueryClient, Durations } from "@azure/monitor-query";
import { DefaultAzureCredential } from "@azure/identity";

const monitorWorkspaceId = "<workspace_id>";
const logsQueryClient = new LogsQueryClient(new DefaultAzureCredential());

const result = await logsQueryClient.queryWorkspace(
  monitorWorkspaceId,
  `StormEvents
        | summarize event_count = count() by State
        | where event_count > 10
        | project State, event_count
        | render columnchart`,
  { duration: Durations.oneDay },
  {
    includeVisualization: true,
  },
);

console.log("visualization result:", result.visualization);

Because the structure of the visualization payload varies by query, a Record<string, unknown> return type is used. It contains the raw JSON response. For example:

{
  "visualization": "columnchart",
  "title": "the chart title",
  "accumulate": false,
  "isQuerySorted": false,
  "kind": null,
  "legend": null,
  "series": null,
  "yMin": "NaN",
  "yMax": "NaN",
  "xAxis": null,
  "xColumn": null,
  "xTitle": "x axis title",
  "yAxis": null,
  "yColumns": null,
  "ySplit": null,
  "yTitle": null,
  "anomalyColumns": null
}

Metrics query

The following example gets metrics for an Azure Metrics Advisor subscription. The resource URI must be that of the resource for which metrics are being queried. It's normally of the format /subscriptions/<id>/resourceGroups/<rg-name>/providers/<source>/topics/<resource-name>.

To find the resource URI:

  1. Navigate to your resource's page in the Azure portal.
  2. From the Overview blade, select the JSON View link.
  3. In the resulting JSON, copy the value of the id property.
import { DefaultAzureCredential } from "@azure/identity";
import { MetricsQueryClient, Durations } from "@azure/monitor-query";

const metricsResourceId = "<the Resource Id for your metrics resource>";

const tokenCredential = new DefaultAzureCredential();
const metricsQueryClient = new MetricsQueryClient(tokenCredential);

const metricNames = [];
const metricDefinitions = metricsQueryClient.listMetricDefinitions(metricsResourceId);
for await (const { id, name } of metricDefinitions) {
  console.log(` metricDefinitions - ${id}, ${name}`);
  if (name) {
    metricNames.push(name);
  }
}

const [firstMetricName, secondMetricName] = metricNames;
if (firstMetricName && secondMetricName) {
  console.log(`Picking an example metric to query: ${firstMetricName} and ${secondMetricName}`);
  const metricsResponse = await metricsQueryClient.queryResource(
    metricsResourceId,
    [firstMetricName, secondMetricName],
    {
      granularity: "PT1M",
      timespan: { duration: Durations.fiveMinutes },
    },
  );

  console.log(
    `Query cost: ${metricsResponse.cost}, interval: ${metricsResponse.granularity}, time span: ${metricsResponse.timespan}`,
  );

  const metrics = metricsResponse.metrics;
  console.log(`Metrics:`, JSON.stringify(metrics, undefined, 2));
  const metric = metricsResponse.getMetricByName(firstMetricName);
  console.log(`Selected Metric: ${firstMetricName}`, JSON.stringify(metric, undefined, 2));
} else {
  console.error(`Metric names are not defined - ${firstMetricName} and ${secondMetricName}`);
}

In the preceding sample, metric results in metricsResponse are ordered according to the order in which the user specifies the metric names in the metricNames array argument for the queryResource function. If the user specifies [firstMetricName, secondMetricName], the result for firstMetricName will appear before the result for secondMetricName in the metricResponse.

Handle metrics query response

The metrics queryResource function returns a QueryMetricsResult object. The QueryMetricsResult object contains properties such as a list of Metric-typed objects, interval, namespace, and timespan. The Metric objects list can be accessed using the metrics property. Each Metric object in this list contains a list of TimeSeriesElement objects. Each TimeSeriesElement contains data and metadataValues properties. In visual form, the object hierarchy of the response resembles the following structure:

QueryMetricsResult
|---cost
|---timespan (of type `QueryTimeInterval`)
|---granularity
|---namespace
|---resourceRegion
|---metrics (list of `Metric` objects)
    |---id
    |---type
    |---name
    |---unit
    |---displayDescription
    |---errorCode
    |---timeseries (list of `TimeSeriesElement` objects)
        |---metadataValues
        |---data (list of data points represented by `MetricValue` objects)
            |---timeStamp
            |---average
            |---minimum
            |---maximum
            |---total
            |---count
|---getMetricByName(metricName): Metric | undefined (convenience method)

Example of handling response

import { DefaultAzureCredential } from "@azure/identity";
import { MetricsQueryClient, Durations } from "@azure/monitor-query";

const metricsResourceId = "<the Resource Id for your metrics resource>";

const tokenCredential = new DefaultAzureCredential();
const metricsQueryClient = new MetricsQueryClient(tokenCredential);

console.log(`Picking an example metric to query: MatchedEventCount`);

const metricsResponse = await metricsQueryClient.queryResource(
  metricsResourceId,
  ["MatchedEventCount"],
  {
    timespan: {
      duration: Durations.fiveMinutes,
    },
    granularity: "PT1M",
    aggregations: ["Count"],
  },
);

console.log(
  `Query cost: ${metricsResponse.cost}, granularity: ${metricsResponse.granularity}, time span: ${metricsResponse.timespan}`,
);

const metrics = metricsResponse.metrics;
for (const metric of metrics) {
  console.log(metric.name);
  for (const timeseriesElement of metric.timeseries) {
    for (const metricValue of timeseriesElement.data!) {
      if (metricValue.count !== 0) {
        console.log(`There are ${metricValue.count} matched events at ${metricValue.timeStamp}`);
      }
    }
  }
}

Query metrics for multiple resources

To query metrics for multiple Azure resources in a single request, use the MetricsClient.queryResources method. This method:

Each Azure resource must reside in:

  • The same region as the endpoint specified when creating the client.
  • The same Azure subscription.

Furthermore:

import { DefaultAzureCredential } from "@azure/identity";
import { MetricsClient } from "@azure/monitor-query";

const resourceIds = [
  "/subscriptions/0000000-0000-000-0000-000000/resourceGroups/test/providers/Microsoft.OperationalInsights/workspaces/test-logs",
  "/subscriptions/0000000-0000-000-0000-000000/resourceGroups/test/providers/Microsoft.OperationalInsights/workspaces/test-logs2",
];
const metricsNamespace = "<YOUR_METRICS_NAMESPACE>";
const metricNames = ["requests", "count"];
const endpoint = " https://<endpoint>.monitor.azure.com/";

const credential = new DefaultAzureCredential();
const metricsClient = new MetricsClient(endpoint, credential);

const result = await metricsClient.queryResources(resourceIds, metricNames, metricsNamespace);

For an inventory of metrics and dimensions available for each Azure resource type, see Supported metrics with Azure Monitor.
