OCI Instances are virtual machines, it is a “computers made of software” that you can use to run any software you’d run on a physical computer. Like a physical machine, a virtual machine has its own operating system (Windows, Linux, etc.), storage, networking, configuration settings, and software, and it is fully isolated from other VMs running on that host.
Use the Oracle Cloud integration to discover and collect metrics against the OCI Instances.
Setup
To set up the Oracle Cloud integration and discover the OCI Instances service, do the following:
Create a Oracle Cloud (OCI) integration if not available in your installed integrations.
You can select
OCI Instancesduring integration or you can edit the existing integration and selectOCI Instances.Scan to discover the resources at any time independent of the predefined schedule.
Once the scan is completed, you can view the OCI Instances 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 Instances as shown below:
Supported metrics
| OpsRamp Metric | Oracle Cloud Metric | Metric Display Name | Unit | Description | Aggregation Type |
|---|---|---|---|---|---|
| oci_instance_CpuUtilization | CpuUtilization | CPU Utilization | percentage | Activity level from CPU. Expressed as a percentage of total time. For instance pools, the value is averaged across all instances in the pool. | mean |
| oci_instance_DiskBytesRead | DiskBytesRead | Disk Read Bytes | bytes | Read throughput. Expressed as bytes read per interval. | rate |
| oci_instance_DiskBytesWritten | DiskBytesWritten | Disk Write Bytes | bytes | Write throughput. Expressed as bytes written per interval. | rate |
| oci_instance_DiskIopsRead | DiskIopsRead | Disk Read I/O | operations | Activity level from I/O reads. Expressed as reads per interval. | rate |
| oci_instance_DiskIopsWritten | DiskIopsWritten | Disk Write I/O | operations | Activity level from I/O writes. Expressed as written per interval. | rate |
| oci_instance_LoadAverage | LoadAverage | Load Average | count | Average system load calculated over a 1-minute period. | mean |
| oci_instance_MemoryAllocationStalls | MemoryAllocationStalls | Memory Allocation Stalls | count | Number of times page reclaim was called directly. | mean |
| oci_instance_MemoryUtilization | MemoryUtilization | Memory Utilization | percentage | Space currently in use. Measured by pages. Expressed as a percentage of used pages. For instance pools, the value is averaged across all instances in the pool. | mean |
| oci_instance_NetworksBytesIn | NetworksBytesIn | Network Receive Bytes | bytes | Network receipt throughput. Expressed as bytes received. | rate |
| oci_instance_NetworksBytesOut | NetworksBytesOut | Network Transmit Bytes | bytes | Network transmission throughput. Expressed as bytes transmitted. | rate |
| oci_instance_instance_accessibility_status | InstanceAccessibilityStatus | Instance accessibility status | count | The accessibility status of a VM instance. A value of 1 indicates that the instance is unresponsive due to an issue with the infrastructure or the instance itself. A value of 0 indicates that an accessibility issue has not been detected. If the instance is stopped, then the metric does not have a value. | max |
| oci_instance_instance_status | instance_status | Instance Status | count | The status of a running VM or bare metal instance. A value of 0 indicates that the instance is available (up). A value of 1 indicates that the instance is not available (down) due to an infrastructure issue. If the instance is stopped, then the metric does not have a value. This metric is available for both VM and bare metal instances. | mean |
| oci_instance_maintenance_status | maintenance_status | Maintenance Status | count | The maintenance status of a VM or bare metal instance. A value of 0 indicates that the instance is not scheduled for an infrastructure maintenance event. A value of 1 indicates that the instance is scheduled for an infrastructure maintenance event. This metric is available for both VM and bare metal instances. | mean |
