This article shows monitoring solutions for SAP administrators to efficiently monitor their SAP systems. The solutions that is described here works for SUSE® Linux Enterprise Server 12 SP3 to 15 SP2.

Revision History: SAP Monitoring

1 Conceptual overview #

Starting from the idea of improving user experience, SUSE engineering worked on how to monitor High Availability clusters that manage SAP workloads (SAP HANA and SAP NetWeaver).

The exporters shown here export their metrics which can be combined and integrated with Prometheus and Grafana to produce complex dashboards.

SUSE supports Prometheus and Grafana through SUSE Manager 4.0. Some Grafana dashboards for SAP HANA, SAP S/4HANA, SAP NetWeaver, and the cluster monitoring are provided by SUSE via Grafana community dashboards.

2 Terminology #

Grafana: An interactive visualization and analytics Web application. It provides methods to visualize, explore, and query your metrics, and trigger alerts.
Prometheus: A systems monitoring and alerting toolkit. It collects and evaluates metrics, displays the result, and triggers possible alerts when an observed condition is true. Metrics can be collected from different targets at given intervals.

3 Installing exporters #

Installation of an exporter follows always the same pattern. Execute the following steps:

Procedure 1: General way #

Install the package. All package are available in SUSE Linux Enterprise Server for SAP Applications.
(Optional) Copy the configuration file to /etc/EXPORTER_DIR. The exact folder name is different for each exporter. This step depends on the exporter. If you skip this step, the default configuration is used.
Start the daemon:
```
systemctl start NAME_OF_DAEMON
```

The above procedure is automatically done by each of the Salt formulas described in Article “SAP Automation”.

4 SAP HANA database exporter #

Exports SAP HANA database metrics. The exporter can to export the metrics from more than one database or tenant. This multi_tenant option is enabled by default.

Package:prometheus-hanadb_exporter

Export metrics in prometheus format #

Memory metrics
CPU metrics
Disk usage metrics
I/O metrics
Network metrics
Top queries consuming time and memory
System replication metrics

5 High Availability cluster exporter #

Enables monitoring of Pacemaker, Corosync, SBD, DRBD and other components of High Availability clusters. Collects metrics to easily monitor cluster status and health.

Link: https://github.com/ClusterLabs/ha_cluster_exporter.

Export metrics in prometheus format #

Pacemaker cluster summary, nodes, and resource status
Corosync ring errors and quorum votes. Currently, only Corosync version 2 is supported.
Health status of SBD devices.
DRBD resources and connections status. Currently, only DRBD version 9 is supported.

6 SAP host exporter #

Enables the monitoring of SAP NetWeaver, SAP HANA, and other applications. The gathered metrics are the data that can be obtained by running the sapcontrol command.

Link: https://github.com/SUSE/sap_host_exporter.

Exports metrics (for SAP S/4HANA, SAP NetWeaver, or SAP HANA hosts) in prometheus format #

SAP start service process list
SAP enqueue server metrics
SAP application server dispatcher metrics
