Overview

LogicMonitor’s SAP HANA monitoring package leverages the SAP JDBC package to monitor and alert on the status of the HANA database in SAP systems.

Compatibility

Logicmonitor’s SAP HANA package has been developed with version 2.0 of SAP HANA on-premise server and version 4.0 of the SAP HANA cloud. It may work on older versions. Installations of SAP using databases other than HANA are not supported by this package.

Setup Requirements

Follow these steps to set up monitoring for HANA databases in SAP systems.

Prerequisites

• Requires Logicmonitor Collector version 30.000 or above.
• SAP HANA JDBC Jar installed on the Collector.
• (Recommended) For on-premises installations, use SNMP to monitor Linux installations used by SAP HANA.

Install the SAP JDBC on a Collector

LogicMonitor uses the SAP JDBC connector to get data from SAP HANA. The SAP JDBC is .jar file that must be installed on the Collector.

• This suite was tested with the version 2.8.14 of the JDBC driver but may work with other versions. See the Maven Repository for SAP JDBC.
• For instructions for adding this .jar file to the Collector, see Adding Groovy Libraries.

Add Resources Into Monitoring

Add your SAP HANA resources into monitoring if they have not yet been added. For more information on adding resources into monitoring, see Adding Devices.

• For SAP HANA Cloud installations, use the cloud endpoint as the hostname. An example cloud endpoint is: 5f670e4e-bdda-455d-9bee-f24284290121.hana.trial-us10.hanacloud.ondemand.com
• For on-premises installations, we recommend using the DNS name of the SAP service for the hostname. Otherwise, the IPv4 address will also work.
• (Optional) For Linux installations, enable SNMP to monitor each Linux device.

Obtain Credentials for SAP HANA

Logicmonitor needs an SAP HANA user and password to access data. This user needs “read only” access to some specific system tables. Use the SAP SQL console to create a user and give the user access to the tables/views.

Use the following configuration as a guide for creating a user and setting permissions. Your SAP installation may require a different configuration.

• Replace the phrase “Enter Your Password” with the password for the LM_User.
• To use a different username, replace LM_USER with the username of your choice.

CREATE RESTRICTED USER LM2_USER PASSWORD "Enter Your Password" NO FORCE_FIRST_PASSWORD_CHANGE;
ALTER USER LM_USER ENABLE CLIENT CONNECT;

GRANT CATALOG READ TO LM_USER;
GRANT SELECT ON _SYS_STATISTICS.STATISTICS_CURRENT_ALERTS TO LM_USER;
GRANT SELECT ON SYS.M_BACKUP_CATALOG TO LM_USER;
GRANT SELECT ON SYS.M_BLOCKED_TRANSACTIONS TO LM_USER;
GRANT SELECT ON SYS.M_CACHES TO LM_USER;
GRANT SELECT ON SYS.M_CONNECTION_STATISTICS TO LM_USER;
GRANT SELECT ON SYS.M_CONNECTIONS TO LM_USER;
GRANT SELECT ON SYS.M_DATABASE TO LM_USER;
GRANT SELECT ON SYS.M_DATABASES TO LM_USER;
GRANT SELECT ON SYS.M_DATABASE_HISTORY TO LM_USER;
GRANT SELECT ON SYS.M_DISKS TO LM_USER;
GRANT SELECT ON SYS.M_EXPENSIVE_STATEMENTS TO LM_USER;
GRANT SELECT ON SYS.M_GARBAGE_COLLECTION_STATISTICS TO LM_USER;
GRANT SELECT ON SYS.M_HOST_INFORMATION TO LM_USER;
GRANT SELECT ON SYS.M_HOST_RESOURCE_UTILIZATION TO LM_USER;
GRANT SELECT ON SYS.M_JOB_PROGRESS TO LM_USER;
GRANT SELECT ON SYS.M_LANDSCAPE_HOST_CONFIGURATION TO LM_USER;
GRANT SELECT ON SYS.M_LICENSE TO LM_USER;
GRANT SELECT ON SYS.M_MEMORY TO LM_USER;
GRANT SELECT ON SYS.M_RECORD_LOCKS TO LM_USER;
GRANT SELECT ON SYS.M_SERVICE_MEMORY TO LM_USER;
GRANT SELECT ON SYS.M_SERVICE_STATISTICS TO LM_USER;
GRANT SELECT ON SYS.M_SERVICE_THREADS TO LM_USER;
GRANT SELECT ON SYS.M_SERVICES TO LM_USER;
GRANT SELECT ON SYS.M_SHARED_MEMORY TO LM_USER;
GRANT SELECT ON SYS.M_SYSTEM_OVERVIEW TO LM_USER;
GRANT SELECT ON SYS.M_TABLE_VIRTUAL_FILES TO LM_USER;
GRANT SELECT ON SYS.M_TRANSACTIONS TO LM_USER;
GRANT SELECT ON SYS.M_VOLUME_IO_STATISTICS TO LM_USER;
GRANT SELECT ON SYS.M_VOLUME_SIZES TO LM_USER;
GRANT SELECT ON SYS.M_VOLUMES TO LM_USER;

Assign Properties to Resources

The following custom properties must be set on the SAP HANA resource within LogicMonitor. For more information on setting properties, see Resource and Instance Properties.

Import LogicModules

Import all the SAP HANA LogicModules from the LogicMonitor Public Repository. See LogicModules in Package.

If these LogicModules are already present, ensure you have the most recent versions. If all setup requirements are complete, data collection will start once the LogicModules are imported.

Considerations

• Multiple ports are needed for multiple database instances. Each database is discovered from the TCP port.
• If a database uses multiple hosts, the hosts should automatically be discovered. Make sure the primary endpoint for HANA is the hostname of the resource.

Troubleshooting

• The “SAP HANA Troubleshooter” DataSource captures configuration and permissions issues. If data is not being returned as expected, navigate to this DataSource in the Resources tree and check for the existence of errors (errors display as instances in the Resources tree). Additionally, any errors captured by the troubleshooter DataSource are included in alert details.
• The modules in this package are designed with a debug mode embedded in the data collection scripts. If issues occur, turn on debug mode by setting the variable debug to “true” to get more information in the output when testing the script in the Collector Debug Facility. For more information on testing scripts in the Collector Debug Facility, see Script Troubleshooting.

LogicModules in Package

LogicMonitor’s package for SAP HANA consists of the following LogicModules. For full coverage, please ensure that all of these LogicModules are imported into your LogicMonitor platform.

When setting static datapoint thresholds on the various metrics tracked by this package’s DataSources, LogicMonitor follows the technology owner’s best practice KPI recommendations. If necessary, we encourage you to adjust these predefined thresholds to meet the unique needs of your environment. For more information on tuning datapoint thresholds, see Tuning Static Thresholds for Datapoints.
