![]() ![]() Load average is a measure of processor load, expressed as the exponentially weighted moving average of processes that are using CPU plus those waiting for CPU time. For example, other tools might express metrics out of 200% on a machine with two CPUs, or 400% for a quad-core processor. This differs from some CPU usage tools which report 100% per CPU or core. On DigitalOcean, total use of all processors combined is indicated by 100%. Alert policies do not distinguish between user and system time. System time is time spent executing kernel-level instructions, while user time is time spent executing userland instructions, which is defined by anything outside of the kernel. In the Droplet graphs, CPU usage is broken down based on Linux’s conception of system and user time. CPU utilization is expressed as a percentage. CPU UtilizationĬPU utilization measures the amount of processor being used at a given time. Metrics can either refer to the resource and unit with which to measure, or the data that is collected about that resource. In computing, a metric is a standard for measuring a computer resource. ![]() This glossary covers the different system resources tracked, the units used to measure them, and how they are represented by DigitalOcean Monitoring. It provides additional Droplet graphs and supports configurable metrics alert policies with integrated email Slack notifications to help you track the operational health of your infrastructure.ĭigitalOcean Monitoring uses a variety of metrics to track system health. DigitalOcean Monitoring is a free, opt-in service that gathers metrics about Droplet-level resource utilization. ![]()
