For support and monitoring, Google Cloud provides the Agent for SAP, for SAP workloads running on Compute Engine VM instances and Bare Metal Solution servers.
As mandated by SAP, to get support from SAP and to enable SAP to meet its service-level agreements (SLAs), you must install Google Cloud's Agent for SAP on all Compute Engine VM instances and Bare Metal Solution servers that run any SAP system. For more information on the support prerequisites, see SAP Note 2456406 - SAP on Google Cloud Platform: Support Prerequisites .
Version 1 of Google Cloud's Agent for SAP is the successor of Google Cloud's monitoring agent for SAP NetWeaver version 2. In addition to the mandatory collection of SAP Host Agent metrics, on Linux, Google Cloud's Agent for SAP includes optional features such as collection of Process Monitoring metrics and Workload Manager evaluation metrics. You can opt in to these features that enable products and services such as Workload Manager for your SAP workloads.For SAP systems running on a Bare Metal Solution server, Google Cloud's Agent for SAP is required when you run SAP NetWeaver connected to any of the following databases:
- SAP HANA
- SAP Adaptive Server Enterprise (ASE)
- SAP MaxDB
- IBM Db2
You install Google Cloud's Agent for SAP on the host alongside the SAP system. For instructions about how to install and configure the agent, validate your installation, and verify that the agent is running as expected, see:
- Install and configure the agent on a Compute Engine VM instance
- Install and configure the agent on a Bare Metal Solution server
If you use the following RHEL or SLES "for SAP" OS images that Google Cloud provides, then Google Cloud's Agent for SAP is packaged with the OS images:
- RHEL: all "for SAP" images
- SLES: SLES 15 SP4 for SAP and later versions
Metrics collected by the agent
Version 1 of Google Cloud's Agent for SAP enables the collection of the following metrics:
SAP Host Agent metrics
The SAP Host Agent metrics collection is enabled by default. Google Cloud's Agent for SAP collects and sends all the required information that SAP mandates to the SAP Host Agent, including metrics about the following:
- CPUs, for example, CPU utilization.
- Persistent disk storage, for example, disk throughput and latency.
- Memory, for example, memory consumption.
- Networks, for example, network bandwidth.
- Configuration, including information about the host machine and its environment.
The metrics collected by Google Cloud's Agent for SAP are determined by SAP. For a description of metrics that the agent collects, see SAP Note 2469354 - Key Monitoring Metrics for SAP on IaaS Infrastructure .
Process Monitoring metrics
On Linux, Google Cloud's Agent for SAP can collect Process Monitoring metrics for your SAP applications and their runtime states. The information collected in the Process Monitoring metrics helps you troubleshoot the issues related to your SAP system. In case of issues, with the help of Process Monitoring metrics, Cloud Customer Care can help you reach a resolution more efficiently.
Process Monitoring metrics collection is an optional feature that you can enable after installing Google Cloud's Agent for SAP. For information about the steps to enable Process Monitoring metrics collection, see Configure Google Cloud's Agent for SAP on Linux.
Process Monitoring metrics are fast-changing metrics that are collected every 5 seconds by default.
The data collected using Process Monitoring metrics provide observability for your SAP HANA high-availability cluster configurations. For observability and setting up alerts based on metric thresholds, you need to install the custom dashboards that Google Cloud provides. For more information about dashboard setup, see View the collected metrics.

Pricing
Google Cloud's Agent for SAP is free to install and run. However, you are responsible for the charges that result from reading and writing data to Cloud Monitoring.
For the metrics collected by the agent, Monitoring charges according to the following:
- Monitoring API read calls that exceed the free monthly API allotment.
- Metrics measured by bytes ingested, when the ingested metric data exceeds the free monthly metric allotment.
In Monitoring, ingestion refers to the process of writing time series to Monitoring. Each time series includes some number of data points; those data points are the basis for ingestion charges. For the pricing information, see Monitoring Pricing.
For information about the general concepts in Monitoring, see Metrics, time series, and resources.
Monthly cost estimates
This section illustrates how to estimate monthly costs for collecting metric data for metrics charged by API read calls and bytes ingested.
The examples in this section are for Monitoring pricing as of December, 2022. These examples are intended to illustrate calculations; for comprehensive estimates, use the Pricing Calculator.
The following table summarizes monthly cost estimates for some required and optional features of the agent. For the detailed steps for cost estimation, see SAP Host Agent metrics, Process Monitoring metrics, and Workload Manager evaluation metrics.
| Feature | Type | Number of VM instances | Cost ($) |
|---|---|---|---|
| SAP Host Agent metrics collection | Required | 100 | $209 |
| Process Monitoring metrics collection | Optional | 100 | $1,513.17 |
| Workload Manager evaluation metrics collection | Optional | 500 | $4.41 |
Pricing example for metrics charged by API read calls
The following example illustrates how to get an estimate of costs for collecting metric data for metrics charged by API read calls, such as SAP Host Agent metrics.
SAP Host Agent metrics
Consider a scenario where you have some number of Compute Engine VM instances that make some number of API read calls each month. The variables in the scenario include the following:
- The rate at which a VM instance makes API read calls.
- The number of Compute Engine VM instances.
For this cost estimation, let us consider there are roughly 43,800 minutes in a month.
60 * 730 hours (365 days / 12 months * 24 hours)
Assume a VM instance makes API read calls at the rate of 5 calls / minute.
For one VM instance, total API read calls at the rate of 5 calls / minute for one month: 219,000 (43,800 * 5)
Let us consider that you have 100 VM instances.
Total number of API read calls per month: 21,900,000
(219,000 * 100)
Number of API read calls per month after free allotment: 20,900,000
(21,900,000 - 1,000,000 = 20,900,000)
Approximate cost per month for 100 VM instances: $209
(20,900,000 / 1000) * 0.01
| No. of reads | Rate ($/1000 reads) | Cost ($) | |
|---|---|---|---|
| Free allotment/month | 1,000,000 | 0.00 | $0.00 |
| Chargeable | 20,900,000 | 0.01 | $209 |
| Total | 21,900,000 | $209 |
Pricing example for metrics charged by bytes ingested
The following example illustrates how to get an estimate of costs for collecting metric data for the metrics charged by bytes ingested, such as Process Monitoring metrics and Workload Manager evaluation metrics.
Process Monitoring metrics
Consider a scenario where you have some number of Compute Engine VM instances that are writing data from some number of metrics each month. The variables in the scenario include the following:
- The rate at which the metric data is written.
- The number of metrics.
- The number of Compute Engine VM instances.
For this cost estimation, let us consider there are roughly 43,800 minutes in a month.
60 * 730 hours (365 days / 12 months * 24 hours)
For one metric, writing data at the rate of 1 data point / 5 seconds, that is, 12 data points / minute for one month:
- Total data points is: 525,600 (43,800 minutes * 12 data points)
- Total volume ingested is:
- 4,204,800 bytes (525,600 data points * 8 bytes)
- This is 4.01000977 MiB (4,204,800 bytes / 1,048,576 bytes/MiB)
Let us consider that you have 100 VM instances, each writing 15 metrics.
Total monthly ingestion: 6,015.01466 MiB
4.01000977 MiB for one metric * 1500 (100 VM instances * 15 metrics)
Approximate cost per month 100 VM instances: $1,513.17
(6,015.01466 - 150) * 0.258
| MiB ingested | Rate ($/MiB) | Cost ($) | |
|---|---|---|---|
| Free allotment/month | 150 | 0.00 | $0.00 |
| Chargeable | 5,865.01466 | 0.258 | $1,513.17 |
| Total | 6,015.01466 | $1,513.17 |
Workload Manager evaluation metrics
Consider a scenario where you have some number of Compute Engine VM instances that are writing data from some number of metrics each month. The variables in the scenario include the following:
- The rate at which the metric data is written.
- The number of metrics.
- The number of Compute Engine VM instances.
For this cost estimation, let us consider there are roughly 43,800 minutes in a month.
60 * 730 hours (365 days / 12 months * 24 hours)
For one metric, writing data at the rate of 1 data point / 300 seconds, that is, 0.2 data points / minute for one month:
- Total data points is: 8,760 (43,800 minutes * 0.2 data points)
- Total volume ingested is:
- 70,080 bytes (8,760 data points * 8 bytes)
- This is 0.0668335 MiB (70,080 bytes / 1,048,576 bytes/MiB)
Let us consider that you have 500 VM instances, each writing 5 metrics.
Total monthly ingestion: 167.08375 MiB
0.0668335 MiB for one metric * 2,500 (500 VM instances * 5 metrics)
Approximate cost per month 500 VM instances: $4.41
(167.08375 - 150) * 0.258
| MiB ingested | Rate ($/MiB) | Cost ($) | |
|---|---|---|---|
| Free allotment/month | 150 | 0.00 | $0.00 |
| Chargeable | 17.08375 | 0.258 | $4.41 |
| Total | 167.08375 | $4.41 |
Supported operating systems
Google Cloud's Agent for SAP supports all operating systems that are supported by SAP NetWeaver and SAP HANA. For details, see the list of supported operating systems for SAP NetWeaver and list of supported operating systems for SAP HANA.
Authentication and access
Google Cloud's Agent for SAP requires an Identity and Access Management (IAM) service account for authentication with Google Cloud and for permission to access Google Cloud resources.
IAM roles that are assigned to the service account determine which Google Cloud resources the agent has permission to interact with.
Unless you use an existing or default service account, you need to create the service account in your Google Cloud project and assign one or more roles to the service account.
Specify a service account
If the agent is running on a Compute Engine VM instance, then the agent uses the service account of the host VM by default. The host VM service account is usually a service account with limited roles that you or one of your colleagues create, but it can instead be the Compute Engine default service account, which has broad permissions by default.
If the agent is running on a Bare Metal Solution server, you need to create a service account with a JSON service account key. For information, see Set up a service account.
For more information about service accounts, roles, and permissions, see:
- Creating and managing service accounts
- Compute Engine Access control overview
- Monitoring IAM overview
Required IAM roles
Whether you use a new, existing, or default service account, the service account must include roles that grant the required permissions to the agent.
For collecting SAP Host Agent metrics on VM instances, the predefined
IAM role
Compute Viewer (roles/compute.viewer)
grants permission to get and
list Compute Engine resources, without being able to read the data
stored on them. And, the predefined IAM role Monitoring Viewer (roles/monitoring.viewer)
grants permission
to view Monitoring data.
For collecting SAP Host Agent metrics on a Bare Metal Solution server, the agent does not access the Google Cloud APIs, so does not require an IAM service account or permissions.
For Process Monitoring metrics and Workload Manager evaluation metrics,
in addition to the Compute Viewer (roles/compute.viewer)
and Monitoring Viewer (roles/monitoring.viewer)
roles, the predefined IAM role Monitoring Metric Writer(roles/monitoring.metricWriter)
grants permission to write metrics to Monitoring.
For collecting the Process Monitoring metrics for SAP HANA, if you
use Secret Manager, then the predefined role
Secret Manager Secret Accessor (roles/secretmanager.secretAccessor)
grants permission to access secrets that are stored in Secret Manager.
Access to Google Cloud APIs
Compute Engine recommends configuring your VM instances to allow full access to all Cloud APIs and using only the IAM permissions of the instance service account to restrict access to Google Cloud resources. For more information, see Create a VM that uses a user-managed service account.
If you limit access to the Cloud APIs on a VM instance, then for SAP Host Agent metrics, Google Cloud's Agent for SAP requires the following minimum Google Cloud API access scopes on the host VM instance:
- Compute Engine: Read Only
- Stackdriver Monitoring API: Read Only
For Process Monitoring metrics and Workload Manager evaluation metrics,
the access scopes of the host VM instance must have the write access to publish
metric data to your Google Cloud projects.
When you create a new Compute Engine VM instance, it is automatically
configured with the
write access scope, https://www.googleapis.com/auth/monitoring.write.
If the agent is not running on a Compute Engine VM instance, then you need to establish connection to Google Cloud APIs. See Configuring Private Google Access for on-premises hosts for details.
Metrics in Monitoring
For Process Monitoring metrics and Workload Manager evaluation metrics, Google Cloud's Agent for SAP sends the data that it retrieves from your SAP systems to Monitoring as custom metric data. To send the data, the agent uses the Monitoring API, which is enabled by default when you create a Google Cloud project.
For an overview of Monitoring, see Introduction to Monitoring.
Find the metrics data in Monitoring
The metrics data from Google Cloud's Agent for SAP is available to view as soon as Monitoring receives it. To find and visualize the collected data, you can use Metrics Explorer. For more information about finding the metrics data in Monitoring, see Google Cloud's Agent for SAP Operations guide.
For more information about visualizing the collected data in Monitoring, see:
- Using dashboards and charts
- Filter charted data
- Metrics Explorer
- Monitoring in the Google Cloud console
Dashboard definitions on GitHub
On GitHub, you can find the custom dashboard definitions for
SAP HANA that you can install in your Google Cloud project.
See the dashboards/google-cloud-agent-for-sap directory in the
GoogleCloudPlatform/monitoring-dashboard-samples
repository on GitHub.
