Testing for mishaps you can predict is essential. Chaos engineering is a method of testing distributed software that deliberately introduces failure and faulty scenarios to verify its resilience in the face of random disruptions. Practitioners subject software to a controlled, simulated crisis to test for unstable behavior.

A Dynatrace Managed cluster may lack the necessary hardware to process all the additional incoming data. The cluster sizing doesn’t match requirements because a large number of hosts were added to monitoring after the initial sizing, and the cluster needs to be expanded. All this automatically and with the same hardware.
