Using Coralogix PHP SDK requires these mandatory parameters:
PRIVATE KEY - A unique ID which represents your company. This ID will be sent to your mail once you register to
APPLICATION NAME - The name of your main application. For example, a company named “SuperData” could insert the “SuperData Production” string parameter; or if they want to debug their test environment, they might insert the “SuperData – Test”.
SUBSYSTEM NAME - Your application probably has multiple subsystems. For example: Backend servers, Middleware, Frontend servers etc. In order to help you examine and filter the data you need, inserting the subsystem parameter is vital.
