Overview of Trento

Trento is a comprehensive cloud-native, distributed monitoring solution, and it consists of three main components:

• Agent: Single background process that runs on each host in the target infrastructure
• Wanda: Responsible to orchestrate checks executions on a target infrastructure among the installed Trento Agents.
• Web (current repository): The control plane of the Trento Platform, which works in conjunction with the Agents and Wanda to discover, observe, monitor, and check the target SAP infrastructure.

Trento architecture

See the architecture document for additional details.

Features of Trento

SAP HANA HA Automated discovery

The central server integrates with the agents discoveries by collecting information about the target SAP infrastructure and then detects different kinds of scenarios and reacts accordingly.

See also Trento Agent for additional information.

Configuration validation

Trento is able to execute a variety of configuration health checks (a.k.a. the HA Config Checks) among the installed Trento Agents.

• Pacemaker, Corosync, SBD, SAPHanaSR and other generic SUSE Linux Enterprise for SAP Application OS settings
• Specific configuration audits for SAP HANA Scale-Up Performance-Optimized scenarios deployed on MS Azure cloud.

See Trento Wanda for additional information.

Reactive Control Plane

By leveraging modern approaches to software architecture and engineering and top-notch technologies, we built a reactive system that provides real-time feedback about the changes in the target infrastructure.
