A method for configurable in-application event logging may include receiving, from a client device, one or more user inputs specifying at least one of an event of interest associated with an operation of a software application and a data to collect in response to the event of interest. A logging agent may be configured, based on the user inputs, to respond to the specified event of interest by generating one or more log messages including the specified data. The logging agent may be as a first programming code embedded within a second programming code implementing the software application such that the logging agent is able to access a context of each executing instance of the software application.
