In order to achieve a reasonably high level of availability, especially for actively developed applications, it's important to debug failures quickly. Kubernetes can speed debugging by surfacing causes of fatal errors in a way that can be display using [`kubectl`](/docs/user-guide/kubectl/kubectl) or the [UI](/docs/user-guide/ui), in addition to general [log collection](/docs/user-guide/logging). It is possible to specify a `terminationMessagePath` where a container will write its 'death rattle'?, such as assertion failure messages, stack traces, exceptions, and so on. The default path is `/dev/termination-log`.
