If you're using version 2 of Google Cloud's Agent for SAP, then we recommend that you switch to the latest version of the agent as soon as possible. For information about how to update Google Cloud's Agent for SAP, see Update Google Cloud's Agent for SAP .
This guide shows you how to configure version 2 of Google Cloud's Agent for SAP to collect the Workload Manager evaluation metrics from your SAP systems.
For information about this feature, see Workload Manager evaluation using Google Cloud's Agent for SAP .
Before you begin
- Validate your installation of Google Cloud's Agent for SAP. For instructions, see the installation guide for your scenario .
- If you have installed the agent on a Bare Metal Solution server, then make sure that you have completed the required prerequisites and set up a service account. For instructions, see Configure Google Cloud's Agent for SAP on Linux .
Set IAM roles
To allow Google Cloud's Agent for SAP collect the Workload Manager evaluation metrics, you must ensure that the service account being used by your Compute Engine instance or Bare Metal Solution server includes the following roles:
- Compute Viewer (
roles/compute.viewer
) - Monitoring Metric Writer (
roles/monitoring.metricWriter
) - Secret Manager Secret Accessor (
roles/secretmanager.secretAccessor
) , if you use Secret Manager for storing SAP HANA database password.
To add these required roles to your service account, follow these steps:
-
In the Google Cloud console, go to the IAMpage.
-
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 Addand 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 Editbutton for the service account that you want to edit.
-
Select the required role from the list of available roles:
- Compute Viewer
- Monitoring > Monitoring Metric Writer
- Secret Manager > Secret Manager Secret Accessor
-
Click Addor Saveto apply the roles to the service account.
Enable Workload Manager evaluation metrics collection
To enable the collection of Workload Manager evaluation metrics using Google Cloud's Agent for SAP, follow these steps:
-
Establish an SSH connection with your Compute Engine instance or Bare Metal Solution server.
-
Open the agent's configuration file:
/etc/google-cloud-sap-agent/configuration.json
-
In the
collection_configuration
section, for the parametercollect_workload_validation_metrics
, set the valuetrue
. -
To enable the collection of
workload.googleapis.com/sap/validation/hanasecurity
metric that enables the security evaluation rules in Workload Manager, add theworkload_validation_db_metrics_config
section aftercollect_workload_validation_metrics
, and then specify the following parameters:-
hana_db_user
: specify the user account that is used to query the SAP HANA instance. -
hana_db_password_secret_name
: specify the name of the secret in Secret Manager that stores the user account's password. -
hostname
: specify the identifier for the machine, either local or remote, that hosts your SAP HANA instance. -
port
: specify the port on which your SAP HANA instance accepts queries.
For information about these parameters, see Configuration parameters .
-
-
Optionally, under the
cloud_properties
section, you can update the parameter values that are set automatically. To do so, add thecloud_properties
section to your configuration file, and then specify the required parameters and their values. -
Save the configuration file.
-
Restart the agent for the new settings to take effect:
sudo systemctl restart google-cloud-sap-agent

Int
The collection frequency of the SAP HANA database metrics, in seconds,
for Workload Manager evaluation.
Default is 3600
seconds.
Although you can update the collection frequency of the
SAP HANA database metrics, we recommend that you use
the default value. If you need to modify the default value, then add the workload_validation_db_metrics_frequency
parameter under
the collection_configuration
section and provide the required
value. Make sure that you don't set a collection frequency greater
than 3600
seconds.
