Tiivistelmä
This thesis presents a snapshot on how to instrument a web application with New Relic. The final objective is to verify if it is possible to collect custom metrics, logs, and errors, and display the data in the application. By doing this, it will be possible to gather real time insights, correlate data, and centralize metrics in one platform reducing maintenance overload and improving productivity.
This thesis begins by investigating the core functionalities of New Relic and the requirements for the data to be collected. It is followed by a summary of the different possible approaches to forward data from the application to the observability platform, and finally, by the implementation process and creation of dashboard to visualize the data.
By the end of this thesis, it will be presented a dashboard with custom metrics, logs, and errors that are successfully collected by the New Relic PHP Agent. Being a starting point for the web application to understand the functionalities of New Relic, how data can be collected and displayed, and to support future improvements of the instrumentation and observability implemented.
