What are System metrics?

Metrics represent raw resource usage or behavior data that can be observed and collected from a system. These can be low-level usage summaries provided by the operating system, or they can be high-level data types associated with a particular function or activity of a component, such as requests processed per second or membership in a pool of web servers. Some metrics are shown in terms of overall capacity, while others are shown as rates, which indicate the “utilization” of components.

Often the simplest metrics to start with are those already provided by the operating system to show the utilization of the underlying physical resources. Data on disk space, CPU utilization, swap utilization, etc. are already available, provides immediate value, and can be transferred to your monitoring system with little additional effort. Many web servers, database servers, and other software also provide their own metrics that can be shared.


Why should you collect System metrics? 

Other components, especially your own application, may need to add code or interfaces to expose metrics of interest. Collecting and publishing metrics is sometimes referred to as adding instrumentation to your service.

Metrics are useful because they provide insight into system behavior and health, especially when analyzed in aggregate. They represent the raw footage that surveillance systems use to create a complete picture of the environment, automate responses to change, and alert people when necessary. Metrics are baseline values ​​used to understand historical trends, correlate various factors, and measure changes in performance, consumption, or error rates.

Metrics are the data in your system, and monitoring is the process of collecting, combining, and analyzing these values ​​to increase your knowledge of the characteristics and behavior of your components. Data about the environment is collected from various sources and fed into monitoring systems that store, aggregate, visualize and trigger automatic responses when certain thresholds are met. Logstail takes over this role, making your job easier and saving you valuable time.
