Since we are going to be running locally on a VM we need to define a test.yaml for Squid.  The easiest way to do this is to copy one of the existing Grok-based configs (SnortYAF) and tailor it for Squid.  

...

mkdir /usr/metron/0.1BETA/config/topologies/squid

cp /usr/metron/0.1BETA/config/topologies/snortyaf/test.yaml /usr/metron/0.1BETA/config/topologies/squid/test.yaml

vi /usr/metron/0.1BETA/config/topologies/squid/test.yaml

And edit your config to look like this:

name: "squid-test"

config:

    topology.workers: 1

 

 

components:

    -   id: "parser"

        className: "org.apache.metron.parsing.parsers.GrokParser"

        constructorArgs:

            - "../Metron-MessageParsers/src/main/resources/patterns/squid"

            - "SQUID_DELIMITED"

        configMethods:

            -   name: "withMetronHDFSHome"

                args:

                    - ""

    -   id: "writer"

        className: "org.apache.metron.writer.KafkaWriter"

        constructorArgs:

            - "${kafka.broker}"

    -   id: "zkHosts"

        className: "storm.kafka.ZkHosts"

        constructorArgs:

            - "${kafka.zk}"

    -   id: "kafkaConfig"

        className: "storm.kafka.SpoutConfig"

        constructorArgs:

            # zookeeper hosts

            - ref: "zkHosts"

            # topic name

            - "${spout.kafka.topic.squid}"

            # zk root

            - ""

            # id

            - "${spout.kafka.topic.squid}"

        properties:

            -   name: "ignoreZkOffsets"

                value: false

            -   name: "startOffsetTime"

                value: -2

            -   name: "socketTimeoutMs"

                value: 1000000

 

spouts:

    -   id: "kafkaSpout"

        className: "storm.kafka.KafkaSpout"

        constructorArgs:

            - ref: "kafkaConfig"

 

bolts:

    -   id: "parserBolt"

        className: "org.apache.metron.bolt.ParserBolt"

        constructorArgs:

            - "${kafka.zk}"

            - "${spout.kafka.topic.squid}"

            - ref: "parser"

            - ref: "writer"

 

streams:

    -   name: "spout -> bolt"

        from: "kafkaSpout"

        to: "parserBolt"

        grouping:

            type: SHUFFLE
