AWS Kinesis Agent configuration to process and parse multi line logs.


Within Kinesis Agent configuration, in order to preprocess data/logs before it send to Kinesis Stream or Firehose directly, we can use it's dataProcessingOptions  configuration settings.

Below are the three configuration options available for now.
  • SINGLELINE
  • CSVTOJSON
  • LOGTOJSON
There are many standard data/log format Kinesis agent is aware of and it don't need any pre processing such as Apache logs, but there are many cases our logs like Wildfly logs, custom data, stack traces which is not predefined, we need to use Kinesis Agent's dataProcessingOptions  to parse into a JSON value.

So we will be using here option "CSVTOJSON" and "SINGLELINE" option to parse our custom logs.

Here is our sample log looks like, every individual complete log line is highlighted with a different color.
14:36:21,753 | INFO  --- xyzignorelogs-1842 | orrelationIdGeneratorInterceptor | 1135 - com.xyz.ppp.def-orchestration-api-impl-bundle-v1 - 0.0.2211 | Execution started in CorrelationIdGeneratorInterceptor : somerandomnumber09897w9w7w
14:36:21,753 | INFO  --- xyzignorelogs-1842 | LogInInterceptor                 | 1135 - com.xyz.ppp.def-orchestration-api-impl-bundle-v1 - 0.0.2211 | Execution started in LogInInterceptor : somerandomnumber09897w9w7w
14:36:21,759 | INFO  ---  xyzignorelogs-1842 | Util                             | 1134 - com.xyz.ppp.def-orchestration- 0.0.2211 | {
  "consumer-workflow-DATA" : {
    "correlationId" : "somerandomnumber09897w9w7w",
    "flowName" : "carate",
    "Url" : "www.cyberkeeda.com",
    "Request/Response Type" : "tracecustomer",
    "API request" : {"fromAddress": "LA", "country" : "US", "DOB": "19-12-1977"}
  }
}
Before we do anything, we will tell agent to read our logs as multiline and for this we need to define the start of the string with a regex pattern.

Kinesis agent will treat a next line only when it again finds the same pattern.
From above logs we can clearly find that every new line of our log start with below time strings.
14:36:21,753 | INFO  
14:36:21,753 | INFO
14:36:21,759 | INFO 
    
So to process the above log file in JSON format, before it sends to stream.
We will use below configuration
{
    "flows": [
        {
            "filePattern": "/tmp/app.log*",
            "kinesisStream": "myapplogstream",
            "multiLineStartPattern": "^[0-9]{2}-[0-9]{2}-[0-9]{2}",
            "dataProcessingOptions": [
                {
                    "optionName": "SINGLELINE"
                },
                {
                    "optionName": "CSVTOJSON",
                    "customFieldNames": [ "timeframe", "message" ],
                    "delimiter": "---"
                }
            ]

        }
    ]
}

    
We have defined a regex to meet our requirement as "^[0-9]{2}-[0-9]{2}-[0-9]{2}" to let kinesis agent know our where does our multi-line starts with.

Further we are converting the entire line as SINGLELINE and dividing the entire line based on delimiter.
Here we are using "---", so overall we are dividing the entire lines into two part and thus seperating them by a "Comma (',')" to make it a CSV value.
"customFieldNames": [ "timeframe", "message" ],
Further As we are breaking the single line into CSV value with only two fields, we are using their field name as "timeframe" and "message"

Thus final processed line to stream will be sent as below
"timeframe" :"14:36:21,753 | INFO", "message": "xyzignorelogs-1842 | orrelationIdGeneratorInterceptor | 1135 - com.xyz.ppp.def-orchestration-api-impl-bundle-v1 - 0.0.2211 | Execution started in CorrelationIdGeneratorInterceptor : somerandomnumber09897w9w7w"

"timeframe" :"14:36:21,753" | INFO",  "message": "xyzignorelogs-1842 | LogInInterceptor                 | 1135 - com.xyz.ppp.def-orchestration-api-impl-bundle-v1 - 0.0.2211 | Execution started in LogInInterceptor : somerandomnumber09897w9w7w"


"timeframe" :" "14:36:21,759 | INFO", "message": "xyzignorelogs-1842 | Util                             | 1134 - com.xyz.ppp.def-orchestration- 0.0.2211 | {
  "consumer-workflow-DATA" : {
    "correlationId" : "somerandomnumber09897w9w7w",
    "flowName" : "rate",
    "Url" : "www.cyberkeeda.com",
    "Request/Response Type" : "tracecustomer",
    "API request" : {"fromAddress": "LA", "country" : "US", "DOB": "19-12-1977"}
  }
}"

    
Do let me know, if it works for you or not.

AWS Elasticsearch Service with Kinesis Data Stream and Kinesis Data Firehose


EKK -- ElasticSearch Kinesis Kibana


EKK Stack is a collective approach of using end to end AWS services to use elasticserach services.

We will replace all opensource products within a normal ELK stack with AWS Service. 

EKK Stack all together can manage and parse huge amount of log data, that can be used further for analytical, troubleshooting , central monitoring and alarming purposes using it's efficient GUI and without taking the burden of infrastructure availability and scalabilty, we can use all AWS service to deploy the entire elasticsearch services.

So below is the architecture we will be using and we will be enlisting all the AWS services used as compared to usual ELK Stack


EKK Stack Component

    • Elasticsearch and Kibana will be replaced by Amazon ElasticSearch Services, it includes Kibana dashboard too.
    • Logstash will be replaced by Kinesis Data Sream and Kinesis Data Firehose
    • Logstash client agent ( FileBeat ) client agent will be replaced by Kinesis Agent.
    You can have a look on one of my previous post of "How to install ELK Stack" to get an overview of how ELK stack works together with it's components.

    I have created a very basic AWS Cloudformation script, and will try to explain it and later that can be used too, lets start with parameters section.

    Parameters :
    # Author : Jackuna (https://github.com/Jackuna)
    # Website : www.cyberkeeda.com
    AWSTemplateFormatVersion: 2010-09-09
    Description: CloudFormation Stack to Create an AWS Managed Elastic Service using Kinesis Streaming Services.
    
    Parameters:
      LogBucketName:
        Type: String
        Description: Name of Amazon S3 bucket for log [a-z][a-z0-9]*
    
      KinesisStreamName:
        Type: String
        Description: Name of Kinesis Stream Name for log [a-z][a-z0-9]*
    
      ElasticsearchDomainName:
        Type: String
        Description: Name of Elasticsearch domain for log [a-z][a-z0-9]*
    
      ElasticsearchIndexName:
        Type: String
        Description: Name of Elasticsearch index from Kinesis Firehose [a-z][a-z0-9]*
        
      FirehoseName:
        Type: String
        Description: DeliveryStream for ES and S3 [a-z][a-z0-9]*
    Here are the parameters explained
    • LogBucketName: One need to feed the name of the S3 bucket name, that will be used to keep failed records and logs while ingesting data to elasticsearch domain from Amazon Kinesis Firehose stream.
    • ElasticsearchDomainName: Creation of AWS Elasticsearch starts with creation of domain within it, so that in case we wish to manage multiple elasticsearch services it could be identified as a separate domain.
    • ElasticsearchIndexName: Name of the Index, it will be used later while configuring indexes on Kibana dashboard.
    • KinesisStreamName: Name of the Kinesis Data Stream.
    • FirehoseName : Name of Kinesis Firehose data Stream.

    LogBucket:

    This resource section is responsible to create S3 bucket, meant to keep failed logs.
    LogBucket:
        Type: 'AWS::S3::Bucket'
        Properties:
          BucketName: !Ref "LogBucketName"
          AccessControl: Private

    Once the Stack is Created, we need Kinesis agent installed on clients that will ship logs to AWS Kinesis data stream

    Installation and Configuration of Kinesis Agent:

    We are using amzon linux here as client to ship log data, install it using below command
    $ sudo yum install –y aws-kinesis-agent
    For Redhat/CentOS
    $ sudo yum install –y https://s3.amazonaws.com/streaming-data-agent/aws-kinesis-agent-latest.amzn1.noarch.rpm
    Open and edit kinesis agent config file and edit it as per your requirement, below is basic configuration.
    { 
       "flows": [
            { 
                "filePattern": "/tmp/you_app.log*", 
                "deliveryStream": "your-kinesis-deliverystreamname"
            } 
       ] 
    } 
    For more detailed option of configuration, please visit the official AWS link.

    Save and start the agent.
    $ sudo service aws-kinesis-agent start
    There are detailed multiple ways for preprocessing logs at kinesis agent, do look into attached official link and use the one that suits your log.
