Best Monitoring Software

Monitoring software is a category of tools that observe infrastructure and applications and alert engineering teams when something is wrong, ideally before users are affected. These tools collect metrics, traces, and logs, establish performance baselines, and report deviation from them.

Solutions in this category cover network monitoring, application performance monitoring, observability, cloud infrastructure monitoring, log monitoring, database monitoring, website monitoring, and enterprise monitoring. Organizations evaluate them on alerting, automation, real-time monitoring, performance baselining, and reporting. Companies benefit from shorter time to detection and resolution. Alert volume that outpaces a team's capacity to act undermines that value regardless of coverage.
