#Endpoint definition

We use gocf-client which will call the CF endpoint /v2/info to get Auth., doppler endpoint.

But for doppler endpoint you can overwrite it with --doppler-address as we know some people use different endpoint.

Event documentation

See the dropsonde protocol documentation for details on what data is sent as part of each event.

Caching

We use boltdb for caching application name, org and space name.

We have 3 caching strategies:

Pull all application data on start.
Pull application data if not cached yet.
Pull all application data every "cc-pull-time".

To test and build

    # Setup repo
    go get github.com/pivotalservices/firehose-to-loginsight
    cd $GOPATH/src/github.com/pivotalservices/firehose-to-loginsight
    glide install --strip-vendor —strip-vcs
    # Test
	ginkgo -r .

    # Build binary
    go build

Run against a bosh-lite CF deployment

    go run main.go \
		--debug \
		--skip-ssl-validation \
		--api-endpoint="https://api.10.244.0.34.xip.io"

Parsing the logs with Logstash
