 Monitor provides an aggregated view of all of your integration activities with visibility into each execution and the ability to drill into the details of any execution. Filter the logs or executions screens to look for failures across all integrations or filter down to a specific integration or even a specific process flow within a specific integration. Monitor acts as an operational control panel for your business, providing your DevOps teams with one central environment through which to view and manage your federated architectures.
