As a Dev or Ops it’s hard to focus on the things that really matter. Applications, systems, tools and other environments are generating notifications at a frequency and amount greater than you are able to deal with. It's a problem for every Dev and Ops professional.
Alerts are used to identify trends, spikes or dips in your metrics and events – for example to detect low free memory, high page-fault errors or unavailable database servers. With the right alerts in place you can get notifications or signals of problems before they escalate or respond quickly before it takes a business service down which could affect your customers.
