Availability Tracking

A Physical Server is considered available (or Up) as long as the Avantra Agent installed on it is running. In cases when the agent was down, but the server itself was still running, the Avantra Agent determines (during the startup phase) since when a Physical Server was running by reading the server’s uptime parameter. It then generates availability data back in the past. For time periods the Avantra Agent cannot determine the system is running the availability is considered Unknown.

A Virtual Cluster Server is considered available as long as there is an Avantra Agent running on the Physical Server the Virtual Cluster Server is active on (see above).

An SAP System is considered available if the SystemAlive check is Ok. Unlike other Availability Data, the data for an SAP system is collected constantly in the background and is updated immediately.

An SAP Instance is considered available if the following checks are Ok:

In other words, an SAP Instance is considered UP as long as the Avantra Agent can log in. If the login attempt fails, the SAP Instance is considered DOWN.

A database is considered available if the DBConnect check is Ok.

An SAP BusinessObjects System is considered available, as long as the BO_Alive check status is Ok.

A cloud service is considered available, as long as the SO_Connect check status is Ok.

Im Kontext der End-to-End-Anwendungsüberwachung gibt es auch die sogenannte Endpunkt-Verfügbarkeit. Ihre Verfügbarkeit entspricht dem Prüfstatus des E2E-Prüfdatensatzes.
