Google Cloud's Agent for SAP is required for SAP support of SAP systems running on Google Cloud, including SAP NetWeaver, SAP HANA, SAP ASE, SAP MaxDB, and others.
When you install Google Cloud's Agent for SAP on a Compute Engine VM instance, for SAP Host Agent metrics, the agent combines monitoring data from Cloud Monitoring and the Compute Engine APIs and provides that data to the SAP Host Agent.
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
For information about the operating systems supported by Google Cloud's Agent for SAP, see Supported operating systems.
To install and configure version 2 of Google Cloud's Agent for SAP on a Bare Metal Solution server, see Install Google Cloud's Agent for SAP on a Bare Metal Solution server.
Installation overview
On Linux, you install Google Cloud's Agent for SAP by using standard operating
system package management commands: on RHEL, the yum
command; on SLES, the
zypper
command. The package management command completes the following tasks:
- Downloads Google Cloud's Agent for SAP.
- Creates the agent as a Linux
systemd
service, namedgoogle-cloud-sap-agent
. - Enables and starts the service,
google-cloud-sap-agent
.
On Windows, you install Google Cloud's Agent for SAP by using the GooGet package
management command, googet
. The package management command completes the
following tasks:
- Downloads Google Cloud's Agent for SAP.
Creates a Windows service named
google-cloud-sap-agent
and a scheduled task that runs every minute to check if the service is still running and, if necessary, restart it.
Prerequisites for the agent
Before you install Google Cloud's Agent for SAP, you need to ensure that the following prerequisites are met.
Set the required IAM roles
At a minimum, the
service account
that Google Cloud's Agent for SAP uses must include the
Compute Viewer (roles/compute.viewer
),
Monitoring Viewer (roles/monitoring.viewer
),
and Workload Manager Insights Writer (roles/workloadmanager.insightWriter
)
roles.
To add a required role to your service account, follow these steps:
In the Google Cloud console, go to the IAM page.
Select your Google Cloud project.
Identify the service account to which you want to add a role.
- If the service account isn't already on the principals list, then it doesn't have any roles assigned to it. Click Add and enter the email address of the service account.
- If the service account is already on the principals list, then it has existing roles. Click the Edit button for the service account that you want to edit.
Select the required role from the list of available roles:
- Compute Engine > Compute Viewer
- Monitoring > Monitoring Viewer
- Workload Manager > Workload Manager Insights Writer
Click Add or Save to apply the roles to the service account.
Enable access to Google Cloud APIs
Compute Engine recommends configuring your VM instances to allow all access scopes to all Cloud APIs and using only the IAM permissions of the instance service account to control access to Google Cloud resources. For more information, see Create a VM that uses a user-managed service account.
If you do limit access to the Cloud APIs, then Google Cloud's Agent for SAP requires the following minimum Cloud API access scopes on the host VM instance:
- Cloud Platform: Enabled
- Compute Engine: Read Only
- Stackdriver Monitoring API: Read Only
If you are running SAP applications on a VM instance that does not have an external IP address, then you need to enable Private Google Access on the VM's subnet so that Google Cloud's Agent for SAP can access Google APIs and services. To enable Private Google Access on a subnet, see Configuring Private Google Access.
Install the agent
We recommend that you install the latest version of Google Cloud's Agent for SAP, which supports more features. For instructions, see Install and configure Google Cloud's Agent for SAP on a Compute Engine VM instance.
To install version 2 of Google Cloud's Agent for SAP, contact Cloud Customer Care.
After you install Google Cloud's Agent for SAP and the SAP Host Agent, validate the installation of Google Cloud's Agent for SAP, as described in Validate your installation of the agent.
Validate your installation of the agent
To verify that the agent is running, select your operating system, and then follow the steps:
Linux
Establish an SSH connection with your host VM instance.
Run the following command:
systemctl status google-cloud-sap-agent
If the agent is functioning properly, then the output contains
active (running)
. For example:google-cloud-sap-agent.service - Google Cloud Agent for SAP Loaded: loaded (/usr/lib/systemd/system/google-cloud-sap-agent.service; enabled; vendor preset: disabled) Active: active (running) since Fri 2022-12-02 07:21:42 UTC; 4 days ago Main PID: 1337673 (google-cloud-sa) Tasks: 9 (limit: 100427) Memory: 22.4 M (max: 1.0G limit: 1.0G) CGroup: /system.slice/google-cloud-sap-agent.service └─1337673 /usr/bin/google-cloud-sap-agent
Windows
Use RDP to connect to the VM instance.
As an administrator, run the following command from PowerShell:
$(Get-Service -Name 'google-cloud-sap-agent' -ErrorAction Ignore).Status
If the agent is running, then the status showsRunning
.
If the agent isn't running, then restart the agent.
Verify that SAP Host Agent is receiving metrics
To verify that the infrastructure metrics are collected by Google Cloud's Agent for SAP and sent correctly to the SAP Host Agent, follow these steps:
- In your SAP system, enter transaction
ST06
. In the overview pane, check the availability and content of the following fields for the correct end-to-end setup of the SAP and Google monitoring infrastructure:
- Cloud Provider:
Google Cloud Platform
- Enhanced Monitoring Access:
TRUE
- Enhanced Monitoring Details:
ACTIVE
- Cloud Provider:
Configure Google Cloud's Agent for SAP on Linux
After you install Google Cloud's Agent for SAP, optionally, you can enable other features of the agent by performing the following configurations. By default, the collection of only the SAP Host Agent metrics is enabled.
- Configure Process Monitoring metrics collection
- Configure Workload Manager evaluation metrics collection
- Configure SAP HANA monitoring metrics collection.
