Monitoring is in many organisations well set up. Logs, metrics and dashboards are available and systems are actively monitored. Yet, at a certain point, a new problem often arises: it takes more and more time to understand exactly what is happening.<\/strong><\/p>\n

Incidents affect multiple systems simultaneously, dependencies become less visible, and different teams look at different tools and insights. The environment still works, but the overview slowly disappears. That is often the moment when observability becomes relevant.<\/p>\n

Monitoring works, until complexity increases<\/h2>\n

Many IT environments grow step by step. New applications are added, infrastructures change, and data spreads across multiple platforms and environments. Monitoring usually grows along with them, but often remains focused on individual components.<\/p>\n

This creates a situation where signals are visible, but the coherence is missing. Teams see notifications and deviations, but it takes more and more time to find the causes or to fully understand the impact.<\/p>\n

This does not directly lead to major disruptions, but rather to greater dependence on specialist knowledge, longer analyses, and less oversight of what is happening within the environment.<\/p>\n

Signals that observability is becoming relevant<\/h2>\n

There are a number of recognisable signs that show traditional monitoring is no longer sufficient.<\/p>\n

For example, when:<\/p>\n
