![]() ![]() This will write a log whenever the endpoint “ /logs/demo” of the API is hit and hence can be used to track endpoint hits. For example inside any method of LogController we can write logs as follows. Now, we can use the LOGGER object to write logs wherever required. private static final Logger LOGGER = LoggerFactory.getLogger(SecondController.class) In the getLogger() method of LoggerFactory we have to pass the reference of the class for which we need the logger. Next, we have to create an instance of the Logger class using the LoggerFactory class. To write logs in any Java application using log4j2, first we have to import the dependencies via pom.xml file as follows. In this blog, we will be working with log4j2 only. ![]() ![]() There are many libraries that provide support for writing logs in Java Applications like logback, log4j2 etc. Repository for this blog: Application Logging POC Writing Structured Logs Getting Started with Logging So, CF provides dedicated Application Logging service to support in writing and analyzing structured logs. For example, when the amount of logs is too much Loggregator tends to either overwrite or drop some of the log lines which hampers the log analysis. Although this component can be used to create and manage logs, it’s not very efficient in doing so. Loggregator is the Cloud Foundry component responsible for streamlining logs from applications and other system components that interact with the applications. Application Logging is a service provided by SAP CF to help developers in identifying an error in the application and also helps in troubleshooting to find the root cause of the error. ![]()
