The VM cluster provides a link between your Exadata Database Service on Cloud@Customer infrastructure and Oracle Databases you deploy. The VM cluster contains an installation of Oracle Clusterware, which supports databases in the cluster. In the VM cluster definition, you also specify the number of enabled CPU cores, which determines the amount of CPU resources that are available to your databases.
Use the Oracle Cloud integration to discover and collect metrics against the OCI Cloud VM Clusters.
Setup
To set up the Oracle Cloud integration and discover the OCI Cloud VM Clusters service, do the following:
Create a Oracle Cloud (OCI) integration if not available in your installed integrations.
You can select
OCI Cloud VM Clustersduring integration or you can edit the existing integration and selectOCI Cloud VM Clusters.Scan to discover the resources at any time independent of the predefined schedule.
Once the scan is completed, you can view the OCI Cloud VM Clusters resource under Infrastructure > Resources > Oracle Cloud category.
Create a template. See Create a Template for more information on how to create a template.
Refer to Assign a Template on how to assign a template to a resource.
Click the Metrics tab to view the monitoring data of OCI Cloud VM Clusters as shown below:
Supported metrics
| OpsRamp Metric | Oracle Cloud Metric | Metric Display Name | Unit | Description | Aggregation Type |
|---|---|---|---|---|---|
| oci_cloudvmcluster_CpuUtilization | CpuUtilization | CPU Utilization | percentage | Percent CPU utilization. | mean |
| oci_cloudvmcluster_ASMDiskgroupUtilization | ASMDiskgroupUtilization | ASM Diskgroup Utilization | percentage | Percentage of usable space used in a Disk Group. Usable space is the space available for growth. DATA disk group stores our Oracle database files. RECO disk group contains database files for recovery such as archives and flashback logs. | max |
| oci_cloudvmcluster_MemoryUtilization | MemoryUtilization | Memory Utilization | percentage | Percentage of memory available for starting new applications, without swapping. The available memory can be obtained via the following command: cat /proc/meminfo. | mean |
| oci_cloudvmcluster_SwapUtilization | SwapUtilization | Swap Utilization | percentage | Percent utilization of total swap space. | mean |
| oci_cloudvmcluster_LoadAverage | LoadAverage | Load Average | count | System load average over 5 minutes. | mean |
| oci_cloudvmcluster_NodeStatus | NodeStatus | Node Status | count | Indicates whether the host is reachable. | mean |
