Let’s delve into the intricate world of service metrics offered by the top OCI services: Compute, Storage, and Networking.
Compute Metrics
Starting with OCI_compute, this metric namespace furnishes insights into the performance characteristics of block volumes linked to compute instances. Monitoring block volume activity levels, including read and write operations, as well as read-write throughput, aids in optimizing performance.
Instance Metadata Request reveals vital information about running instances, such as attached virtual network interface cards (vNICs) and custom metadata. Meanwhile, OCI_compute_infrastructure_health provides metrics for monitoring the health status of bare metal instances, essential for tracking hardware components like CPU and memory.
Monitoring Compute Instances
Instant status metric verifies the availability of virtual machine instances, while maintenance status ensures vigilance over planned infrastructure maintenance. OCI_computeagent emits metrics via the compute instance monitoring plugin, enabling monitoring of CPU and memory utilization, disk I/O activity, network throughput, load averages, and memory allocation efficiency.
Storage Metrics
OCI_objectstorage, dedicated to object storage, offers metrics for monitoring bucket size and object count. OCI_blockstore, focusing on block storage, provides volume-specific metrics for read/write throughput, operations, throttling, guaranteed IOPS, and cross-region replica status.
Networking Insights
Within the oci_vcn namespace, metrics for vNICs facilitate monitoring of packet reception and transmission, ingress/egress bytes, and dropped packets due to security list rules or throttling.
Exploring NAT Gateway Metrics
The oci_nat_gateway namespace concentrates on metrics for NAT gateways, crucial for outbound internet connections. Monitoring traffic to and from the gateway, including dropped packets, aids in troubleshooting potential issues, such as NAT port exhaustion.
Conclusion
In summary, we’ve explored various OCI namespaces encompassing compute, storage, and networking, along with their associated metrics and functionalities. These metrics serve as invaluable tools for optimizing performance, ensuring reliability, and troubleshooting potential issues within OCI environments.
