System Performance Monitoring

When we run any application in production, we need to make it stable by avoiding anything that can impact the application's performance; this can be anything, such as the system, database, or any third-party dependencies, since if anything fails it impacts the application. In this section, we'll see how system monitoring can help us to avoid situations where the system can cause the application to outage.

Let's discuss the factors that can hamper application's performance. There can be number of reasons, such as the system memory or CPU creating a bottleneck because of an increase in user hits. In this situation, we can do multiple things, such as optimizing the application if it's possible and increasing the memory or CPU. We can do it to mitigate the outrage of the application, but it's only possible if we're monitoring the system metrics of the servers on which the application has been deployed. Using the monitoring, we can configure the alert whenever the threshold value of any component increases. In this way, you can protect yourself from any application outage because of system performance.
