monitoring
In short and in plain language
Monitoring means watching systems or values on an ongoing basis. It usually runs by itself.
For a website, it can check if the site is up. It can check how fast it loads. Certificates and visibility can be watched too.
If a value is off, an alert can be sent. That way problems are noticed early.
Definition
Monitoring is the ongoing, usually automatic observation of systems or metrics, such as the availability, load time or certificates of a website. If a value deviates, an alert can be triggered so that problems are noticed early.
