Have you had experience setting up log sending and monitoring systems?

Yes, experience in configuring logging and monitoring systems often includes the following steps:

• Selecting and configuring a logging framework (e.g., Logback, Log4j2, SLF4J) for structured and convenient log output.
• Configuring logging levels (ERROR, WARN, INFO, DEBUG) for different packages or classes.
• Setting up log output to files, console, or external systems (e.g., via Logstash).
• Integrating with centralized log collection systems such as ELK Stack (Elasticsearch, Logstash, Kibana) or Grafana Loki.
• Setting up monitoring with tools like Prometheus and Grafana to collect application metrics.
• Using APM (Application Performance Monitoring) systems, such as New Relic, Datadog, to track performance and errors.

Example of a simple Logback configuration (logback.xml file):

<configuration>
    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <file>app.log</file>
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <root level="INFO">
        <appender-ref ref="FILE" />
    </root>
</configuration>

This approach allows for efficient collection, storage, and analysis of logs and metrics to support and develop the application.
