Dynatrace OneAgent is a powerful tool for full-stack monitoring, but it cannot be installed on all device types, such as network devices, storage devices, or outdated operating systems. In these cases, custom devices can be created in Dynatrace to send data using an API or ActiveGate extension, or a simple synthetic monitor can suffice for tasks like checking if an SQL database is active or if a DNS server is operational. The Dynatrace Platform Extension Services team offers solutions for non-web-based protocols, including ping and DNS lookups, through the ActiveGate extension framework and Third-party Synthetic API, with open-source implementations available on GitHub for easy integration. As of Dynatrace version 1.198, an Early Adopter program provides a streamlined process for integrating extensions, allowing users to create and visualize synthetic monitors, link data to Dynatrace applications, and build dashboards. For those needing assistance, the Platform Extension Services team is available to help, and a free 15-day trial of Dynatrace is offered without requiring a credit card.
