Welcome to Gabeat. This is a little process that implements the Elastic Beat interface and gets one data point from the Google Analytics Real Time Data API and sends that data to Elastic so that a user can graph events in Elastic against the data point from Google Analytics (GA). For example, if you have a dashboard in Elastic that shows metrics on the errors in your application's logs, you might want to chart that against page views from GA for your application.

Prerequisites:

1. Note that this version of GABeat has only been tested with Go 1.7 and Beats 5.2.
2. Follow the instructions in Getting Ready in the Beats documentation.
3. Install the non-Go dependences mentioned in Fetching Dependencies and Setting up the Beat. Note that we skipped the "Generating Your Beat" step in the Elastic documentation. That's because the GABeat structure has already been generated.
4. Clone this project into the following location: ${GOPATH}/src/github.com/GeneralElectric/GABeat
5. Get a GA JWT token (these are the credentials to use the GA APIs) and modify _meta/beat.yml google_credentials_file config value to point to it. The GA docs explain how to get a token.
6. Modify the ga_ids, ga_metrics, and ga_dimensions fields of _meta/beat.yml to reference your GA account view ID and the data point you want to collect. To find your account view ID: 1. Log into GA with your usual credentials. 1. Click on the account name in the upper left-hand corner of the home page. 1. Click on accounts -> Properties & Apps -> views. 1. The view ID is displayed below each view name in the menu.
7. A note about proxies: You will need to have the http_proxy environment variable set to a GE-approved proxy to download the code from GE's GitHub. You will likely not be able to use GE's GitHub if your https_proxy environment variable is set. However, you WILL need the https_proxy variable set to download the Go dependencies.

To get running with Gabeat and also install the required Go libraries, run the following command:

make setup

To build the binary for Gabeat run the command below. This will generate a binary in the same directory with the name gabeat.

make

To run Gabeat with debugging output enabled, run:

./gabeat -c gabeat.yml -e -d "*"

To test Gabeat, run the following command:

make testsuite

alternatively:

make unit-tests
make system-tests
make integration-tests
make coverage-report

The test coverage is reported in the folder ./build/coverage/

Each beat has a template for the mapping in elasticsearch and a documentation for the fields which is automatically generated based on etc/fields.yml. To generate etc/gabeat.template.json and etc/gabeat.asciidoc

make update

To clean Gabeat source code, run the following commands:

make fmt
make simplify

To clean up the build directory and generated artifacts, run:

make clean

NOTE!!! I have not tested the packaging!!!

The beat frameworks provides tools to crosscompile and package your beat for different platforms. This requires docker and vendoring as described above. To build packages of your beat, run the following command:

make package

This will fetch and create all images required for the build process. The hole process to finish can take several minutes.
