info

This exporter is set up by default in the relay-proxy.

Configure the GO Module​

To configure your GO module to use the Log exporter, you need to add the following configuration to your ffclient.Config{} object:

example.go
config := ffclient.Config{
    // ...
   DataExporter: ffclient.DataExporter{
        Exporter: &logsexporter.Exporter{
            LogFormat: "[{{ .FormattedDate}}] user=\"{{ .UserKey}}\", flag=\"{{ .Key}}\", value=\"{{ .Value}}\"",
        },
    },
    // ...
}
err := ffclient.Init(config)
defer ffclient.Close()
Field nameMandatoryDefaultDescription
LogFormat[{{ .FormattedDate}}] user="{{ .UserKey}}", flag="{{ .Key}}", value="{{ .Value}}"

LogFormat is the template configuration of the output format of your log.

You can use all the key from the exporter.FeatureEvent + a key called FormattedDate that represents the date with the RFC 3339 Format.
