SAP Monitoring

SUSE® Linux Enterprise Server for SAP Applications · SUSE Linux Enterprise High Availability

Publication Date: September 28, 2024

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.

1 Introduction

The exporters described here make it possible to export metrics that can be combined and integrated with Prometheus and Grafana to produce advanced 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 toolkit that collects and evaluates metrics, displays the result, and triggers possible alerts when an observed condition occurs. Metrics can be collected from different targets at specified intervals.

3 Installing exporters

Installation of an exporter follows the procedure below.

Procedure 1: Exporter installation
  1. Install the package. All package are available in SUSE Linux Enterprise Server for SAP Applications.

  2. (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.

  3. Start the daemon:

    systemctl start NAME_OF_DAEMON

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

4 SAP HANA database exporter

SAP HANA database exporter makes it possible to export SAP HANA database metrics. The tool can export metrics from more than one database and tenant if the multi_tenant option is enabled in the configuration file (enabled by default).

The labels sid (system identifier), insnr (instance number), database_name (database name) and host (machine hostname) are exported for all the metrics.

4.1 Prerequisites

  • A running and reachable SAP HANA database (single or multi-container). It is recommended to run the exporter on the same machine with the SAP HANA database. Ideally, each database should be monitored by one exporter.

  • One of the following SAP HANA connectors:

  • Certain metrics are collected in the SAP HANA monitoring views by the SAP Host agent. To have access to all the monitoring metrics, make sure that the SAP Host agent is installed and running.

4.2 Metrics file

The exporter relies on a metrics file to determine what metrics to export. When the metrics file uses the JSON format, you can use the options listed below.

  • enabled (boolean, optional). Determines whether the query is executed or not. If set to false, the metrics for this query are not executed.

  • hana_version_range (list, optional). The SAP HANA database versions range where the query is available ([1.0.0] by default). If the current database version is not within the specified range, the query is not executed. If the list has only one element, all versions beyond the specified value (including the defined one) are queried.

  • metrics (list) A list of metrics for the query.

  • name (string) A name for the exported metrics.

  • description (string) A description of the metrics.

  • labels (list) A list of labels used to split the records.

  • value (string) A name of the column for the exported value (must match with one of the columns of the query).

  • unit (string) Used unit for the exported value (for example, `mb`).

  • type (enum{gauge}) Defines the type of the exported metric (gauge is the only available option).

Below is an example of a metrics file:

{
  "SELECT TOP 10 host, LPAD(port, 5) port, SUBSTRING(REPLACE_REGEXPR('\n' IN statement_string WITH ' ' OCCURRENCE ALL), 1,30) sql_string, statement_hash sql_hash, execution_count, total_execution_time + total_preparation_time total_elapsed_time FROM sys.m_sql_plan_cache ORDER BY total_elapsed_time, execution_count DESC;":
  {
    "enabled": true,
    "hana_version_range": ["1.0"]
    "metrics": [
      {
        "name": "hanadb_sql_top_time_consumers",
        "description": "Top statements time consumers. Sum of the time consumed in all executions in Microseconds",
        "labels": ["HOST", "PORT", "SQL_STRING", "SQL_HASH"],
        "value": "TOTAL_ELAPSED_TIME",
        "unit": "mu",
        "type": "gauge"
      },
      {
        "name": "hanadb_sql_top_time_consumers",
        "description": "Top statements time consumers. Number of total executions of the SQL Statement",
        "labels": ["HOST", "PORT", "SQL_STRING", "SQL_HASH"],
        "value": "EXECUTION_COUNT",
        "unit": "count",
        "type": "gauge"
      }
    ]
  }
}

4.3 Installing the SAP HANA database exporter

Use the zypper install prometheus-hanadb_exporter command to install the exporter.

You can find the latest development repositories at SUSE's Open Build Service.

To install the exporter from the source code, make sure you have Git and Python 3 installed on your system. Run the following commands to install the exporter with the PyHDB SAP HANA connector:

git clone https://github.com/SUSE/hanadb_exporter
cd hanadb_exporter # project root folder
virtualenv virt
source virt/bin/activate
pip install pyhdb
pip install .

4.4 Configuring the exporter

Use the following example of the config.json configuration file as a starting point.

{
  "listen_address": "0.0.0.0",
  "exposition_port": 9668,
  "multi_tenant": true,
  "timeout": 30,
  "hana": {
    "host": "HOSTNAME",
    "port": 30013,
    "user": "SYSTEM",
    "password": "PASSWORD",
    "ssl": false,
    "ssl_validate_cert": false
  },
  "logging": {
    "config_file": "PATH/logging_config.ini",
    "log_file": "PATH/hanadb_exporter.log"
  }
}

Below is a list of key configuration options.

  • listen_address IP address of the Prometheus exporter (0.0.0.0 by default).

  • exposition_port Port through which the Prometheus exporter is accessible (9968 by default).

  • multi_tenant Export the metrics from other tenants. This requires a connection to the system database (port 30013).

  • timeout Timeout to connect to the database. The app fails if connection is not established within the specified time (even in daemon mode).

  • hana.host Hostname or IP address of the SAP HANA database host.

  • hana.port Port through which the SAP HANA database is accessible.

  • hana.userkey Stored user key (see Section 4.5, “Using the stored user key”). Use this option if you do not want to store the password in the configuration file. The userkey and user/password are mutually exclusive. If both are set, hana.userkey takes priority.

  • hana.user Existing user with access right to the SAP HANA database.

  • hana.password Password of an existing user.

  • hana.ssl Enable SSL connection (false by default). Only available for the dbapi connector.

  • hana.ssl_validate_cert Enable SSL certification validation. This option is required by SAP HANA cloud. Only available for the dbapi connector.

  • hana.aws_secret_name Secret name containing the username and password (see Section 4.6, “Using AWS Secrets Manager”. Use this option when SAP HANA database is stored on AWS. aws_secret_name and user/password are mutually exclusive. If both are set, aws_secret_name takes priority.

  • logging.config_file Python logging system configuration file (by default, WARN and ERROR level messages are sent to the syslog).

  • logging.log_file Logging file (/var/log/hanadb_exporter.log by default)

The logging configuration file follows the Python standard logging system style.

Using the default configuration file, redirects the logs to the file specified in the JSON configuration file and to the syslog (only logging level up to WARNING).

4.5 Using the stored user key

Use this option to keep the database secure (you can use user/password with the SYSTEM user for development, as it is faster to set up). To use the userkey option, the dbapi must be installed (normally stored in /hana/shared/SID/hdbclient/hdbcli-N.N.N.tar.gz and installable with pip3). The key is stored in the client itself. To use a different client, you must create a new stored user key for the user running Python. To do that, use the following command (note that the hdbclient is the same as the dbapi Python package):

/hana/shared/PRD/hdbclient/hdbuserstore set USER_KEY host:30013@SYSTEMDB hanadb_exporter pass

4.6 Using AWS Secrets Manager

Use the AWS Secrets Manager to store the login credentials outside the configuration file when the SAP HANA database is stored on AWS EC2 instance.

  • Create a JSON secret file that contains two key-value pairs. The first pair contains the username key and the actual database user as the value. The second pair has the password key and the actual password as the value. For example:

    {
    """username": "DATABASE_USER",
    "password": "DATABASE_PASSWORD"
    }

    Use the actual secret as the secret name, and pass it in the configuration file as a value for the aws_secret_name entry.

  • Configure read-only access from EC2 IAM role to the secret by attaching a resource-based policy to the secret. For example:

    {
    "Version" : "2012-10-17",
    "Statement" : [
      {
        "Effect": "Allow",
        "Principal": {"AWS": "arn:aws:iam::123456789012:role/EC2RoleToAccessSecrets"},
        "Action": "secretsmanager:GetSecretValue",
        "Resource": "*",
      }
    ]
    }

Tips and recommendations:

  • Set SYSTEMDB as the default database for the exporter to get the tenants data.

  • Do not use the stored user key created for the backup, because the key is created using the sidadm user.

  • Instead of the SYSTEM user, use an account limited to accessing the monitoring tables only.

  • In case you use a user account with the monitoring role, this user must exist in all the databases (SYSTEMDB and tenants).

4.7 Create a new user with the monitoring role

Run the following commands to create a user with the monitoring roles (the commands must be executed in all the databases):

su - prdadm
hdbsql -u SYSTEM -p pass -d SYSTEMDB #(PRD for the tenant in this example)
CREATE USER HANADB_EXPORTER_USER PASSWORD MyExporterPassword NO FORCE_FIRST_PASSWORD_CHANGE;
CREATE ROLE HANADB_EXPORTER_ROLE;
GRANT MONITORING TO HANADB_EXPORTER_ROLE;
GRANT HANADB_EXPORTER_ROLE TO HANADB_EXPORTER_USER;

4.8 Running the exporter

Start the exporter with the hanadb_exporter -c config.json -m metrics.json command.

If the config.json configuration file is stored in the /etc/hanadb_exporter directory, the exporter can be started with the following command (note that the identifier matches with the config.json file without extension):

hanadb_exporter --identifier config

4.9 Running as a service

To run the hanadb_exporter as systemd service, install the exporter using the RPM package as described in Section 4.3, “Installing the SAP HANA database exporter”.

Next, create the configuration file as /etc/hanadb_exporter/my-exporter.json. You can use the example file above as a starting point (the example file is also available in the /usr/etc/hanadb_exporter directory).

You can use the example /usr/etc/hanadb_exporter/metrics.json metrics file.

Adjust the default logging configuration file /usr/etc/hanadb_exporter/logging_config.ini.

Start the exporter as a daemon. Because there are multiple hanadb_exporter instances running on one machine, you need to specify the name of the created configuration file, for example:

# systemctl start prometheus-hanadb_exporter@my-exporter
# systemctl status prometheus-hanadb_exporter@my-exporter
# systemctl enable prometheus-hanadb_exporter@my-exporter
Important
Important: Configure the Prometheus server

The exporter only exposes a port, without pushing the data to the Prometheus server. This means that the Prometheus server must be configured to periodically pull the data from the exporter. This is done by either adding the hanadb_exporter job to the Prometheus server configuration, or by adding hanadb_exporter to an existing job. For example:

- job_name: hana_db
    static_configs:
            - targets:
              - "HOSTNAME:PORT"
Important
Important: Configure firewall

Use the following command to open the port for hanadb_exporter.

# firewall-cmd --zone=ZONE --add-port=PORT/tcp --permanent
# firewall-cmd --reload
# firewall-cmd --list-all --zone=ZONE

Replace ZONE with the actual interface used for the exporter, and PORT with the actual port number of hanadb_exporter(default is 9968).

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 the prometheus format
  • Pacemaker cluster summary, nodes and resources stats

  • Corosync ring errors and quorum votes

  • Health status of SBD devices.

  • DRBD resources and connections status.

5.1 Installation

To install the High Availability cluster exporter on SUSE Linux Enterprise, run the zypper install prometheus-ha_cluster_exporter command.

5.1.1 Enabling systemd service

The High Availability cluster exporter RPM packages comes with the ha_cluster_exporter.service systemd service. To enable and start it, use the following command:

systemctl --now enable prometheus-ha_cluster_exporter

5.2 Using High Availability cluster exporter

You can run the exporter on any of the cluster nodes. Although it is not strictly required, it is advisable to run the exporter on all nodes.

The generated metrics are stored in the /metrics path. By default, the metrics can be accessed through the web interface on port 9664.

Although the exporter can run outside an High Availability cluster node, it cannot export any metric it is not able to collect. In this case, the exporter displays a warning message.

5.3 Configuring High Availability cluster exporter

Before you proceed, make sure that the Prometheus server and the firewall are configured as described in Important: Configure the Prometheus server and Important: Configure firewall

The provided default configuration is designed specifically for the latest version of SUSE Linux Enterprise. If necessary, any of the supported parameters can be modified either via command-line flags or via a configuration file. Use the ha_cluster_exporter --help command for more details on configuring parameters from the command line. Refer to the ha_cluster_exporter.yaml file for an example configuration.

It is also possible to specify CLI flags via the /etc/sysconfig/prometheus-ha_cluster_exporter file.

6 SAP Host exporter

SAP Host exporter is a Prometheus exporter that enables monitoring of SAP systems (SAP NetWeaver applications).

It is a stateless exporter that retrieves runtime data from the SAP system via the SAPControl Web interface on each HTTP request. Exported data include start service processes, Enqueue Server stats, and AS Dispatcher work process queue stats.

Important
Important: Note about metrics

The exporter does not export metrics that it cannot collect. However, as it is irrelevant for the exporter which subsystems are present in the monitored target, failing to collect metrics is not considered a critical failure. However, when certain collectors fail to either register or perform collect cycles, a warning is added to the log. The metrics.md file that ships with the RPM package provides information about the exported metrics. The file is also available in the project's GitHub repository.

Exported metrics (for SAP S/4HANA, SAP NetWeaver, or SAP HANA hosts)
  • SAP start service process list

  • SAP enqueue server metrics

  • SAP application server dispatcher metrics

  • SAP internal alerts

6.1 Installation

The exporter can be installed using the RPM from the Open Build Service. To do this, use the following commands (replace VERSION with the exact version of the target system, for example: SLE_15_SP4):

# zypper addrepo https://download.opensuse.org/repositories/server:/monitoring/VERSION/server:monitoring.repo
# zypper install prometheus-sap_host_exporter

The RPM package ships with an accompanying systemd unit file that can be enabled using the following command:

systemctl --now enable prometheus-sap_host_exporter

Alternatively, you can compile and install the exporter from the source code:

> git clone https://github.com/SUSE/sap_host_exporter
> cd sap_host_exporter
> make
> sudo make install
Note
Note

You can deploy a full SAP NetWeaver cluster via Terraform using SUSE automated SAP/HA deployments. This automatically installs and configures the exporter and the entire Prometheus monitoring stack.

6.2 Using SAP Host exporter

You can run the exporter using the following command:

./sap_host_exporter --sap-control-url SAP_HOST:SAP_CONTROL_PORT

While it is possible to use the exporter to retrieve data from a remote SAP host, it is recommended to run the exporter locally on the target SAP host, and then connect to the SAPControl Web service via Unix domain sockets:

./sap_host_exporter --sap-control-uds /tmp/.sapstream50013

By default, the exporter exposes the metrics in the /metrics path, on port 9680.

6.3 Configuring SAP Host exporter

You can provide optional runtime parameters using command-line flags or via a configuration file. Run the sap_host_exporter --help to view the available flags.

The exporter expects to find the sap_host_exporter.yaml, sap_host_exporter.json, or sap_host_exporter.toml file either in the current working directory, or in one of the following directories: $HOME/.config, /etc, /usr/etc. The first match has precedence, and the command-line flags have precedence over the configuration file.

An example YAML configuration file ships with the RPM package. You can also find the example configuration file in the project's GitHub repository.
