Trento Web
Trento is a bespoke, stand-alone web application, built by SUSE from
the ground up, to facilitate SAP operations, proactively preventing
infrastructural issues by diagnosing common configuration mistakes by
validating systems against SUSE best practices.
It’s meant to complement
SUSE Linux Enterprise
Server for SAP Applications in helping IT organizations run
mission-critical enterprise software.
Documentation
The documentation is available at trento-project.io/web.
Swagger UI is available at trento-project.io/web/swaggerui.
Overview
Trento is a distributed system, and it consists of three main components:
-
Agent: The background edge process that runs on each host in the target infrastructure.
-
Wanda: The checks orchestrator, executing assertions on a target infrastructure using the information collected by Trento Agents.
-
Web (current repository): The web UI and control plane, which works in conjunction with the Agents and Wanda to discover, observe, and validate 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.
