Getting Data In

Splunk not recognizing nested json

I've searched quite some time, but I'm not able to find why Splunk is not recognizing a nested JSON.

Here's how my data/events looks in raw text ( path of the data is SES->SNS->Lambda->HEC)

 

 

{"Records":[{"EventSource":"aws:sns","EventVersion":"1.0","EventSubscriptionArn":"arn:aws:sns:eu-north-1:doesntmatter","Sns":{"Type":"Notification","MessageId":"87b93315-f1f6-56f8-83dc-6b099eb5e18e","TopicArn":"arn:aws:sns:eu-north-1:doesntmatter","Subject":null,"Message":"{\"notificationType\":\"Delivery\",\"mail\":{\"timestamp\":\"2020-11-04T08:57:37.646Z\",\"source\":\"[email protected]\",\"sourceArn\":\"arn:aws:ses:eu-north-1:MYaccountID:identity/[email protected]\",\"sourceIp\":\"X.X.X.X\",\"sendingAccountId\":\"MYaccountID\",\"messageId\":\"011001759279ce6e-67642459-31fa-4f4b-b852-315ea7e8d284-000000\",\"destination\":[\"[email protected]\"],\"headersTruncated\":false,\"headers\":[{\"name\":\"Received\",\"value\":\"from ip-X.X.X.X.eu-north-1.compute.internal (ec2-X.X.X.X.eu-north-1.compute.amazonaws.com [X.X.X.X]) by email-smtp.amazonaws.com with SMTP (SimpleEmailService-d-090KRTZ85) id RANDOM for [email protected]; Wed, 04 Nov 2020 08:57:37 +0000 (UTC)\"},{\"name\":\"Content-Type\",\"value\":\"multipart/mixed; boundary=\\\"===============digits==\\\"\"},{\"name\":\"MIME-Version\",\"value\":\"1.0\"},{\"name\":\"Subject\",\"value\":\"to me from NEW NEW\"},{\"name\":\"To\",\"value\":\"[email protected]\"},{\"name\":\"From\",\"value\":\"[email protected]\"},{\"name\":\"Date\",\"value\":\"Wed, 04 Nov 2020 08:57:37 +0000\"},{\"name\":\"X-Priority\",\"value\":\"3\"},{\"name\":\"X-Splunk-SID\",\"value\":\"digits.2\"},{\"name\":\"X-Splunk-ServerName\",\"value\":\"ip-X.X.X.X.eu-north-1.compute.internal\"},{\"name\":\"X-Splunk-Version\",\"value\":\"8.1.0\"},{\"name\":\"X-Splunk-Build\",\"value\":\"f57c09e87251\"}],\"commonHeaders\":{\"from\":[\"[email protected]\"],\"date\":\"Wed, 04 Nov 2020 08:57:37 +0000\",\"to\":[\"[email protected]\"],\"subject\":\"to me from NEW NEW\"}},\"delivery\":{\"timestamp\":\"2020-11-04T08:57:39.153Z\",\"processingTimeMillis\":1507,\"recipients\":[\"[email protected]\"],\"smtpResponse\":\"250 2.6.0 <[email protected]> [InternalId=digits, Hostname=random hostname] 12107 bytes in 0.057, 206.415 KB/sec Queued mail for delivery\",\"remoteMtaIp\":\"Y.Y.Y.Y\",\"reportingMTA\":\"e240-9.smtp-out.eu-north-1.amazonses.com\"}}","Timestamp":"2020-11-04T08:57:39.198Z","SignatureVersion":"1","Signature":"SIGNATURE","SigningCertUrl":"https://sns.eu-north-1.amazonaws.com/SimpleNotificationService-PEM.pem","UnsubscribeUrl":"https://sns.eu-north-1.amazonaws.com/?Action=Unsubscribe&SubscriptionArn=arn:aws:sns:eu-north-1:doesntmatter","MessageAttributes":{}}}]}

 

 

I'm sending the data to :8088/collector  . Here's the screenshot of how the data looks like in syntax:

I would like to extract some fields from "Message" which is a valid JSON, however I'm not able to do it since Splunk is not recognizing it as a JSON and my knowledge about filtering using rex is below 0  😐 .

I believe it has something to do with the backslashes, but when I use to remove them:

 

 

SEDCMD-replace_backslash = s/\\//g 

 

 


in my props.conf, Splunk stops to recognize the whole event as json and it's not formatting it (showing as raw when I do a search).

My props.conf looks like:

 

 

 

[ses_json_new]
category = Custom
pulldown_type = 1

 

 


If I add to props.conf

 

 

KV_MODE = json

 

 

 

Nothing happens, nor with:

 

 

INDEXED_EXTRACTIONS = json

 

 

Appreciate your help and please excuse me for my nescience.

Thank you.
