Application monitoring software can be divided into two main categories: performance counters and logs.
Performance counters are a type of monitoring tool that collects data about system performance and sends it to the monitoring application as a stream of numbers. Performance counters are generally used to track system activity such as CPU, memory, network I/O, etc. Check out here to get the best application performance monitoring tools.
Logs are a type of monitoring tool that uses log files to track system activity. Log files can be used to monitor system health, identify problems, and track changes over time. A log file is essentially a record of what happened on a system during a certain time period.
Larger companies will have their own set of monitoring tools that can collect log files. But for the most part, it is important to recognize that performance counters and logs are two similar types of monitoring tools but with slightly different purposes.
The purpose of a monitoring tool is generally to provide feedback about the computer’s status in real-time. The goal of performing monitoring is to discover problems as quickly as possible by providing warning signs when something goes wrong or by causing changes before system downtime occurs.
It should be noted that the goal of using a monitoring tool is different from the purpose of using an operating system (OS). OSes were designed from the start to handle certain tasks, thus they can function much better than a monitor application while running. Performing a baseline test on the computer involves identifying devices and software installed that can serve as baseline for future comparison.
