Monitoring strategies
In this section, we will take a look at the monitoring strategies that make microservices observable. It is common to implement the following or more strategies to create a well-defined and holistic monitoring solution.
Application/system monitoring
This strategy is also called a framework-based strategy. Here, the application, or in our case microservice, itself generates the monitoring information within the given context of execution. The application can be dynamically configured based on the thresholds or trigger points in the application data, which can generate tracing statements. It is also possible to have a probe-based framework (such as .NET CLR, which provides hooks to get more information) to generate monitoring data. So, effective instrumentation points themselves can be embedded into the application to facilitate this kind of monitoring. On top of this, the underlying infrastructure, where microservices are hosted, can also raise critical events. These events...
