SAP HANA - Monitoring & Alerting
SAP HANA alert monitoring is used to monitor the status of system resources and services that are running in the HANA system. Alert monitoring is used to handle critical alerts like CPU usage, disk full, FS reaching threshold, etc. The monitoring component of HANA system continuously collects information about health, usage and performance of all the components of HANA database. It raises an alert when any of the component breaches the set threshold value.
The priority of alert raised in HANA system tells the criticality of problem and it depends on the check that is performed on the component. Example − If CPU usage is 80%, a low priority alert will be raised. However, if it reaches 96%, system will raise a high priority alert.
The System Monitor is the most common way to monitor HANA system and to verify the availability of all your SAP HANA system components. System monitor is used to check all key component and services of a HANA system.
