SAP High-performance Analytic Appliance (HANA) is an advanced, multi-model database that uses in-memory storage for high-speed data processing and complex analytics within a single platform. By leveraging its column-oriented architecture, SAP HANA can handle large data volumes with minimal latency.
Monitoring an SAP HANA system on IT-Conductor is crucial for ensuring optimal performance, availability, and reliability of your database environment. Effective monitoring involves setting up user roles and authorizations and enabling specific monitoring permissions. IT-Conductor provides real-time performance insights, proactive alerts, and automated health checks, allowing for swift issue resolution and improved operational efficiency.
Before configuring an SAP HANA system for monitoring in IT-Conductor, follow the instructions below.
Create a monitoring user in each HANA database, including SYSTEMDB, that you intend to monitor by executing the following SQL script.
To verify the user has a lifetime password, run the following script. The result should show an empty 'PASSWORD_CHANGE_TIME' value, as shown in the image below.
Execute the following script to list SQL port numbers for SYSTEMDB and Tenant DBs used in registering.

Important features such as availability, alerts, and services are integrated into IT-Conductor for detailed monitoring.
HANA System Key Metrics
Availability - refers to the operational state and accessibility of the HANA System.
Connection Failures - refer to the events where attempts to establish a connection are unsuccessful.
Heartbeat - refers to the periodic signal sent to the system, enabling real-time detection of system downtime.
Missing Account - refers to the absence of a required user account or resource within the HANA system.
Retriever Failures - refer to the errors or issues encountered during the retrieval process of essential data or information within the SAP HANA system.
SAP HANA Scale-out means combining multiple independent nodes in one system. The remotely configured SAP HANA systems in IT-Conductor are monitored by distributing the tenant databases across multiple nodes.
IT-Conductor monitors multiple databases, such as system databases and tenant databases. They are observed as separate elements, but each tenant is monitored like other primary tenant databases. Furthermore, IT-Conductor offers a drill-down feature for further analysis, correlated alerts, operational status, and performance metrics across applications/DB/OS. The platform also provides time-correlated information about how the monitored system functions and performs.
Jobs refer to scheduled tasks or processes such as backups, data loads, or system updates. Using IT-Conductor, you can monitor the runtime of these jobs to ensure they are completed successfully and within expected time frames.
Hosts refer to physical or virtual machines that host SAP HANA instances and related services. IT-Conductor enables monitoring of host metrics such as memory usage, CPU utilization, disk performance, and status of HANA instances to ensure optimal performance and availability of the SAP HANA system.
The permissions and usage rights granted to operate the SAP HANA software under specific terms. With IT-Conductor, you can monitor the system for license validity and detect any license-related lockdowns to ensure continuous and compliant system operation.
Savepoints are periodic snapshots of the database that capture changes and ensure data persistence. IT-Conductor allows you to monitor the duration of these savepoints to verify that they are completed efficiently and without performance impact.
Monitor all available services that SAP provides, including memory consumption. Services are mapped automatically after configuration, and IT-Conductor tracks the status in real-time.
In addition to the performance metrics overview, IT-Conductor can also give comprehensive information about SQL statements with just a click on the graph. SQL statements give a high-level overview of the database’s workload.
The HANA System Overview Dashboard is a pre-configured dashboard for your HANA systems that you may access from the Service Grid.
It displays vital system information such as database availability, alerts summary, memory, disk consumption, CPU utilization, the most recent successful backup, savepoint duration, indexserver threads, and I/O ratio.
The charts are dynamic, giving you a detailed view of each performance metric when you click them. This allows you to visually correlate data for troubleshooting or analysis while seeing multiple comprehensive metrics on a single dashboard.
HANA Overview dashboards will allow quick recovery actions to prevent and reduce maintenance windows that may cause interruptions or bottlenecks in your daily operations.
