Short Description
An elastic beat to fetch and index tweets by configured screen names.
Full Description

TwitterBeat is a elastic beat that fetches tweets from the Twitter Api (v1.1) and indexes them into elasticsearch. You can configure which screennames that should be fetched.

To use TwitterBeat, you need a valid Twitter Api Key (Consumer Key and stuff), an elasticsearch and Go. Or preferably a docker environment since I made a dockerized version of it.

##Elasticsearch template

To apply the elasticsearch index template:

curl -XPUT 'http://localhost:9200/_template/twitterbeat' -d@etc/twitterbeat.template.json

##Building

For now, I didn't manage to create a makefile :wink:. You need to build it from source, by hand. Download the source, install the dependencies with glide (make sure you have GO15VENDOREXPERIMENT set to 1) and then, run go build or go install.

I would recommend to use the docker image to run a containerized version of the twitterbeat.

##Run in docker

###Environment

ENV variable Default value Description
PERIOD 60s Refresh rate in seconds
SCREEN_NAMES ["@smartive", "@elastic"] Screennames to fetch
ES_HOSTS ["elasticsearch:9200"] Hosts to index tweets to
CONSUMER_KEY null Twitter api consumer key
CONSUMER_SECRET null Twitter api consumer secret
ACCESS_KEY null Twitter api access key
ACCESS_SECRET null Twitter api access secret
BEAT_NAME null Shipper name
BEAT_TAGS null Shipper tags

###Volumes / mount

TwitterBeat has two volumes that can be mounted (both located in /var/twitterbeat):

  • config
  • data

Inside the config folder lies the twitterbeat.yml, the configuration of the beat.

In the data folder, the twittermap.json is stored, which is generated by the beat and keeps track, which tweet id is the newest fetched for each screen name. You might see content like this:

{"@smartive":198759827398749873,"@elastic":87572876363772774}

If you delete the content of this file, twitterbeat will reindex the last 20 tweets of each screenname.

###Example

docker run -d \
       -e CONSUMER_KEY=<consumerKey> \
       -e CONSUMER_SECRET=<secret> \
       -e ACCESS_KEY=<accessKey> \
       -e ACCESS_SECRET=<secret> \
       --link elasticsearch:elasticsearch \
       buehler/go-elastic-twitterbeat

You can mount the data or config volume for custom configuration and persisting of the twittermap.json file.

docker run ... \
       -v $PWD/data:/var/twitterbeat/data \
       -v $PWD/twitterbeat.yml:/var/twitterbeat/config/twitterbeat.yml \
       buehler/go-elastic-twitterbeat
