PutQueryDefinition

Creates or updates a query definition for CloudWatch Logs Insights. For more information, see Analyzing Log Data with CloudWatch Logs Insights.

To update a query definition, specify its queryDefinitionId in your request. The values of name, queryString, and logGroupNames are changed to the values that you specify in your update operation. No current values are retained from the current query definition. For example, imagine updating a current query definition that includes log groups. If you don't specify the logGroupNames parameter in your update operation, the query definition changes to contain no log groups.

You must have the logs:PutQueryDefinition permission to be able to perform this operation.

Request Syntax

   "clientToken": "string",
   "logGroupNames": [ "string" ],
   "name": "string",
   "queryDefinitionId": "string",
   "queryString": "string"
}

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

clientToken

Used as an idempotency token, to avoid returning an exception if the service receives the same request twice because of a network error.

Type: String

Length Constraints: Minimum length of 36. Maximum length of 128.

Pattern: \S{36,128}

Required: No

logGroupNames

Use this parameter to include specific log groups as part of your query definition.

If you are updating a query definition and you omit this parameter, then the updated definition will contain no log groups.

Type: Array of strings

Length Constraints: Minimum length of 1. Maximum length of 512.

Pattern: [\.\-_/#A-Za-z0-9]+

Required: No

name

A name for the query definition. If you are saving numerous query definitions, we recommend that you name them. This way, you can find the ones you want by using the first part of the name as a filter in the queryDefinitionNamePrefix parameter of DescribeQueryDefinitions.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Required: Yes

queryDefinitionId

If you are updating a query definition, use this parameter to specify the ID of the query definition that you want to update. You can use DescribeQueryDefinitions to retrieve the IDs of your saved query definitions.

If you are creating a query definition, do not specify this parameter. CloudWatch generates a unique ID for the new query definition and include it in the response to this operation.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 256.

Required: No

queryString

The query string to use for this definition. For more information, see CloudWatch Logs Insights Query Syntax.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 10000.

Required: Yes
