You can filter query results either through restricting the table elements in the query, or by explicitly adding a filter to the results. A general query like Event returns too many results to be useful. Log Analytics limits results to a maximum of 10, records.

The query runs until it finds a blank line. To use the Time range control, select it in the top bar, and then select a value from the dropdown list, or select Custom to create a custom time range. To set a different time range, you can add an explicit TimeGenerated filter to the query, or use the Time range control. By default, Log Analytics limits queries to a time range of the past 24 hours. In the second example, the search command searches only records in the Events table for the term error. More than one line break splits the query into separate queries.

A single line break makes queries easier to read. The following query retrieves the records from the Event table, and then searches them for the term error in any property. You can add any number of commands to a single query. The pipe character separates commands, so the output of the first command is the input of the next command. Queries can begin with either a table name or a search command. For example, the Event table contains text columns like Computer and numerical columns like EventCategory.Īzure Monitor log queries use a version of the Kusto query language. The tables contain columns, each with a data type shown by the icon next to the column name. The schema tables appear on the Tables tab of the Log Analytics workspace. The Demo schema has several categories from monitoring solutions.įor example, the LogManagement category contains Windows and Syslog events, performance data, and agent heartbeats. A schema is a collection of tables grouped under logical categories.

You can also use your own environment, if you're using Azure Monitor to collect log data on at least one Azure resource. With the demo environment, you won't be able to save queries or pin results to a dashboard. To complete most of the steps in this tutorial, you can use this demo environmentwhich includes plenty of sample data. If you don't have an Azure account, create one for free.

To use Log Analytics, you need to be signed in to an Azure account. For a detailed tutorial on writing log queries, see Get started with log queries in Azure Monitor. For more information about log queries, see Overview of log queries in Azure Monitor. You can use Log Analytics queries to search for terms, identify trends, analyze patterns, and provide many other insights from your data. This tutorial shows you how to use Log Analytics to write, execute, and manage Azure Monitor log queries in the Azure portal.
