Synopsis

Calls the Amazon CloudWatch Logs FilterLogEvents API operation.

Syntax

Get-CWLFilteredLogEvent
-LogGroupName <String>
-EndTime <Int64>
-FilterPattern <String>
-LogGroupIdentifier <String>
-LogStreamNamePrefix <String>
-LogStreamName <String[]>
-StartTime <Int64>
-Unmask <Boolean>
-Interleaved <Boolean>
-Limit <Int32>
-NextToken <String>
-Select <String>
-PassThru <SwitchParameter>
-ClientConfig <AmazonCloudWatchLogsConfig>

Description

Lists log events from the specified log group. You can list all the log events or filter the results using a filter pattern, a time range, and the name of the log stream. You must have the logs:FilterLogEvents permission to perform this operation. You can specify the log group to search by using either logGroupIdentifier or logGroupName. You must include one of these two parameters, but you can't include both. By default, this operation returns as many log events as can fit in 1 MB (up to 10,000 log events) or all the events found within the specified time range. If the results include a token, that means there are more log events available. You can get additional results by specifying the token in a subsequent call. This operation can return empty results while there are more log events available through the token. The returned log events are sorted by event timestamp, the timestamp when the event was ingested by CloudWatch Logs, and the ID of the PutLogEvents request. If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account and view data from the linked source accounts. For more information, see CloudWatch cross-account observability.

In the AWS.Tools.CloudWatchLogs module, this cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-ClientConfig <AmazonCloudWatchLogsConfig>
Amazon.PowerShell.Cmdlets.CWL.AmazonCloudWatchLogsClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-EndTime <Int64>
The end of the time range, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC. Events with a timestamp later than this time are not returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-FilterPattern <String>
The filter pattern to use. For more information, see Filter and Pattern Syntax.If not provided, all the events are matched.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Interleaved <Boolean>
If the value is true, the operation attempts to provide responses that contain events from multiple log streams within the log group, interleaved in a single response. If the value is false, all the matched log events in the first log stream are searched first, then those in the next log stream, and so on.Important As of June 17, 2019, this parameter is ignored and the value is assumed to be true. The response from this operation always interleaves events from multiple log streams within a log group.This parameter is deprecated.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Limit <Int32>
The maximum number of events to return. The default is 10,000 events.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-LogGroupIdentifier <String>
Specify either the name or ARN of the log group to view log events from. If the log group is in a source account and you are using a monitoring account, you must use the log group ARN. You must include either logGroupIdentifier or logGroupName, but not both.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-LogGroupName <String>
The name of the log group to search. You must include either logGroupIdentifier or logGroupName, but not both.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-LogStreamName <String[]>
Filters the results to only logs from the log streams in this list.If you specify a value for both logStreamNamePrefix and logStreamNames, the action returns an InvalidParameterException error.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesLogStreamNames
-LogStreamNamePrefix <String>
Filters the results to include only events from log streams that have names starting with this prefix.If you specify a value for both logStreamNamePrefix and logStreamNames, but the value for logStreamNamePrefix does not match any log stream names specified in logStreamNames, the action returns an InvalidParameterException error.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NextToken <String>
The token for the next set of events to return. (You received this token from a previous call.)
Note: In the AWS.Tools.CloudWatchLogs module, this parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-NextToken $null' for the first call and '-NextToken $AWSHistory.LastServiceResponse.NextToken' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the LogGroupName parameter. The -PassThru parameter is deprecated, use -Select '^LogGroupName' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.CloudWatchLogs.Model.FilterLogEventsResponse). Specifying the name of a property of type Amazon.CloudWatchLogs.Model.FilterLogEventsResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-StartTime <Int64>
The start of the time range, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC. Events with a timestamp before this time are not returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Unmask <Boolean>
Specify true to display the log event fields with all sensitive data unmasked and visible. The default is false.To use this operation with this parameter, you must be signed into an account with the logs:Unmask permission.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
