This planning guide focuses solely on the Process Monitoring metrics collection feature of Google Cloud's Agent for SAP. For information about the agent and all its features, see Google Cloud's Agent for SAP planning guide.
On Linux, Google Cloud's Agent for SAP can help you monitor the processes in your SAP applications and their runtime states. This is delivered through the collection of Process Monitoring metrics, which you can enable after installing the agent on your Compute Engine VM instances or Bare Metal Solution servers.
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. The data collected using Process Monitoring metrics provide observability for your SAP HANA high-availability cluster configurations.
For information about how to configure Google Cloud's Agent for SAP to collect the Process Monitoring metrics, see Configure Process Monitoring metrics collection.
Types of Process Monitoring metrics
From version 2.6 of Google Cloud's Agent for SAP, the Process Monitoring metrics collected by the agent are referred to as follows:
- Fast-changing metrics: This includes
sap/hana/availability
,sap/hana/ha/availability
, andsap/nw/availability
. These metrics are collected at a default frequency of 5 seconds. This collection frequency can be updated using the configuration parameterprocess_metrics_frequency
. - Slow-changing metrics: Process Monitoring metrics other than the
fast-changing ones are referred to as slow-changing. These metrics are
collected at a default frequency of 30 seconds. This collection frequency can
updated using the configuration parameter
slow_process_metrics_frequency
.
Cloud Monitoring pricing
The Process monitoring metrics that Google Cloud's Agent for SAP collects and sends to Monitoring are classified by Monitoring as chargeable metrics and priced by ingested volume.
The frequency at which the agent queries your SAP systems to collect the Process Monitoring metrics affects the volume of metrics that get sent to Monitoring.
Process Monitoring metrics are fast-changing metrics that are collected every 5 seconds by default.
For more information about Monitoring pricing, see Google Cloud Observability pricing.
Sample cost estimate
To see a sample cost estimate for the collection of the Process Monitoring metrics using Google Cloud's Agent for SAP, see Pricing example for metrics charged by bytes ingested.
