These metrics give administrators a clear picture of how well their applications and services are performing. Key performance metrics in this category include latency, request rates, error rates, and CPU usage.

Operational metrics

Operational metrics provide insights into the operational aspects of the cloud infrastructure. These metrics help your team understand resource utilization patterns, identify potential bottlenecks, and optimize the overall operation of the cloud environment. Metrics such as disk usage, memory usage, and I/O operations fall under this category.

Security metrics

Monitoring security metrics helps administrators monitor and assess the effectiveness of security measures, identify potential vulnerabilities, and respond to security incidents. Key security metrics often provide insights into the distribution of workload and storage usage in the cloud environment.

11 key cloud metrics to monitor

Monitoring cloud metrics is essential to ensure the optimal performance, availability, and cost-efficiency of your cloud infrastructure. By keeping a close eye on these cloud metrics, you can proactively identify and address potential issues:

1. CPU utilization

CPU utilization is a measure of the percentage of time the central processing unit (CPU) is actively performing tasks within a given time frame. When CPU utilization is low, it may indicate that the system is underutilized, which could mean resources are over-provisioned or that the workload is too light. Conversely, consistently high CPU utilization can signal that the system is under strain, potentially leading to slower response times or system instability as the demand approaches or exceeds the available processing power.

Monitoring this metric is crucial because it provides insight into the system’s performance and can help in cloud capacity planning, ensuring that compute resources are appropriately scaled to the demands of the applications they support.

DigitalOcean offers Premium CPU-Optimized Droplets, virtual machines designed for high throughput and consistent performance, enabling startups and SMBs to deliver seamless digital experiences for media streaming, online gaming, machine learning, and data analytics. These Droplets use the latest generation of Intel Xeon CPUs to ensure optimal CPU utilization and performance consistency across multiple instances.

2. Load average

Load average is a metric that reflects the average system load over a specified period, providing a snapshot of CPU demand and process queue status. A low load average suggests that the system is handling the workload efficiently, without any significant queue or delay in process execution. On the other hand, a high load average points to a bottleneck where the demand for processing power exceeds what the CPU can immediately provide, causing processes to wait in the queue longer than desired.

This metric is vital to monitor because it helps administrators understand the trends in system demand, enabling preemptive action to redistribute the load or scale resources before users experience performance degradation or system timeouts.

3. Memory

Memory utilization measures the proportion of the system’s total memory that is currently being used to store data and run applications. A low memory utilization indicates that there is plenty of available RAM, which could mean the system is over-provisioned or not heavily tasked, whereas high memory utilization suggests that the system is nearing its capacity, which can lead to swapping and significantly degraded performance.

Understanding memory utilization is essential because memory is a critical resource for application performance; insufficient memory can lead to increased input/output operations as the system resorts to less efficient disk-based storage, slowing down application responsiveness and potentially affecting user experience and system reliability.

4. Disk I/O

Disk I/O (Input/Output) measures the rate at which data is read from and written to storage devices, reflecting the performance of disk operations. Low Disk I/O values may indicate that the system is not heavily reliant on disk operations or that it has sufficient I/O capacity to handle the current workload. In contrast, high Disk I/O can be a sign of a storage bottleneck, where the demand for data read/write operations is approaching or exceeding the disk’s throughput capacity, leading to potential queuing and delays.

Monitoring Disk I/O is crucial as it directly affects application performance and user experience; slow disk access can become a bottleneck in data-intensive applications, causing longer load times and hampering the efficiency of the overall system.

5. Disk usage

Disk usage is a metric that quantifies the amount of storage space occupied by data and applications on a system’s physical or virtual disks. Low disk usage suggests that a system has ample storage space available, which can signal efficient data management—such as regularly cleaning up unnecessary files or using data compression—or over-provisioning. Alternatively, high disk usage can signal that the storage capacity is being maximized, risking data write failures and potential system crashes if the storage limit is reached without expansion or cleanup.

Monitoring disk usage ensures that there is enough space for data growth and operational overhead, which is critical for maintaining data accessibility, system stability, and avoiding interruptions in service due to storage constraints.

6. Bandwidth

Bandwidth measures the maximum rate of data transfer across a network or internet connection within a given time, typically expressed in bits per second. Low bandwidth usage indicates that the network is currently underutilized, which might imply that there is excess capacity or that the system is not experiencing high demand. High bandwidth usage, on the other hand, can suggest network congestion, possibly leading to increased latency and slower data transfers that could impact application performance.

Monitoring bandwidth helps identify potential bottlenecks in network communication, ensuring that there is sufficient capacity to handle data flows, which is essential for maintaining smooth and efficient operations.

7. Latency

Latency measures the time it takes for a data packet to travel from its source to its destination, reflecting the delay experienced in network communication. Low latency signifies a swift data transfer, indicating that the network is responding quickly to requests, which is ideal for time-sensitive applications. High latency, conversely, indicates a slow response time, which can lead to a sluggish user experience, particularly for interactive services such as video conferencing or online gaming.

Monitoring latency is important because it impacts the performance and usability of cloud-based services; excessive delays can disrupt interaction with cloud applications, potentially affecting productivity and user satisfaction.

8. Requests per minute

Requests per minute (RPM) is a metric that measures the number of requests that a server or application receives within a one-minute timeframe, providing a clear picture of traffic volume. A low RPM count may suggest that the application is receiving less traffic than expected, which could be due to off-peak times or indicate a lack of user engagement. A high RPM signals heavy usage, which can strain server resources and may lead to performance issues if the system isn’t scaled appropriately.

Monitoring RPM is crucial for capacity planning and ensuring the robustness of the system. Understanding traffic patterns allows for better resource allocation and cloud scalability to handle peak loads smoothly and maintain a consistent, reliable user experience.

9. Error rate

Error rate measures the percentage of requests that result in an error, giving an indication of the reliability and health of your cloud infrastructure. A low error rate generally indicates a stable system where the majority of requests are processed successfully. A high error rate can signal underlying problems such as bugs in the code, issues with server configuration, or inadequate resources, which can lead to a poor user experience and loss of trust in the service.

Monitoring the error rate helps to identify and diagnose these systemic issues quickly, allowing for proactive measures to improve the application’s stability, functionality, and overall quality of service provided to the end-users.

10. Mean Time to Repair (MTTR)

Mean Time to Repair (MTTR) is a metric that measures the average time required to repair a failed component or system and restore it to full functionality. A low MTTR indicates that the team is able to quickly respond to and resolve issues, minimizing downtime and disruption to services. Conversely, a high MTTR reveals slower repair processes and longer periods of system unavailability, which can have negative impacts on business operations and customer satisfaction.

Monitoring MTTR helps organizations to benchmark and improve their incident response and repair strategies, ensuring that any system outages are dealt with efficiently and effectively, maintaining high levels of service availability and reliability.

11. Mean time between failures (MTBF)

Mean Time Between Failures (MTBF) measures the average time elapsed between system or component failures during normal operation. A high MTBF indicates a more reliable system that typically experiences fewer disruptions over time, reflecting well-designed and robust infrastructure. On the other hand, a low MTBF suggests that failures occur more frequently, which can point to potential issues with system components or operational practices.

Monitoring MTBF provides insights into the overall stability and dependability of your cloud environment, guiding maintenance schedules and improvements. It’s also important for planning and ensuring continuous service delivery, which directly impacts customer satisfaction and business continuity.
