How do I define an AWS MetricFilter FilterPattern to match a JSON-formatted log event in CloudWatch?
I am trying to define a metric filter, in an AWS CloudFormation template, to match JSON-formatted log events from CloudWatch.
Here is an example of the log event:
{
"httpMethod": "GET",
"resourcePath": "/deployment",
"status": "403",
"protocol": "HTTP/1.1",
"responseLength": "42"
}
Here is my current attempt to create a MetricFilter to match the status field using the examples given from the documentation here: FilterAndPatternSyntax
"DeploymentApiGatewayMetricFilter": {
"Type": "AWS::Logs::MetricFilter",
"Properties": {
"LogGroupName": "/aws/apigateway/DeploymentApiGatewayLogGroup",
"FilterPattern": "{ $.status = "403" }",
"MetricTransformations": [
{
"MetricValue": "1",
"MetricNamespace": "ApiGateway",
"DefaultValue": 0,
"MetricName": "DeploymentApiGatewayUnauthorized"
}
]
}
}
I get a "Invalid metric filter pattern" message in CloudFormation.
Other variations I've tried that didn't work:
"{ $.status = 403 }" <- no escaped characters
{ $.status = 403 } <- using a json object instead of string
I've been able to successfully filter for space-delimited log events using the bracket notation defined in a similar manner but the json-formatted log events don't follow the same convention.
