<div id="body32001227"><p id="aom_02_0007__en-us_topic_0263893513_p20570122183712">Components refer to the services that you deploy, including containers and common processes. For example, a workload on the Cloud Container Engine (CCE) is a component, and the Tomcat running on the VM is also a component.</p>
<p id="aom_02_0007__en-us_topic_0263893513_p663215">The component list displays the type, CPU usage, memory usage, and alarm status of each component, helping you learn their running status. You can click a component name to learn more information about the component. AOM supports drill-down from a component to an instance, and then to a container. By viewing the status of each layer, you can implement dimensional monitoring for components.</p>

<h1 class="topictitle1">What Is the Relationship Between the Time Range and Statistical Cycle?</h1>
<div id="body1554884975234"><p id="aom_02_1002__p1943819234322">In AOM, a maximum of 1440 data points can be returned for a single metric query. The relationship between the time range and statistical cycle is as follows:</p>
<p id="aom_02_1002__p0125525133212">Maximum time range = Statistical cycle x 1440</p>
<p id="aom_02_1002__p72001613125514">If you select a time range shorter than or equal to the maximum time range, all the statistical cycles that meet the preceding formula can be selected. For example, if you want to query metrics in the last hour, the available statistical cycles are 1 minute and 5 minutes.</p>
<p id="aom_02_1002__p86871546566">For a <a href="aom_02_0003.html">dashboard</a>, the relationship between the time range and statistical cycle is shown in the following table.</p>

<div id="body1558594630495"><p id="aom_02_1007__en-us_topic_0093966649_p7921891249">Application Operations Management (AOM) is a one-stop, multi-dimensional O&amp;M management platform for cloud applications. It monitors applications and related cloud resources in real time, collects and associates resource metrics, logs, and events to analyze application health status, and provides flexible alarm reporting and data visualization, helping you detect faults in a timely manner and monitor the running status of applications, resources, and services in real time.</p>
<p id="aom_02_1007__ab90f5b1e730440e59c63687e35bda5ae">Specifically, AOM comprehensively monitors and uniformly manages cloud servers, storage devices, networks, web containers, and applications hosted in Docker and Kubernetes, effectively preventing problems, facilitating fault locating, and reducing O&amp;M costs. In addition, AOM provides unified APIs for interconnecting self-developed monitoring or reporting systems. Unlike traditional monitoring systems, AOM monitors services by applications, meeting your requirements for high efficiency and fast iteration. It provides effective IT support for your services, and protects and optimizes your IT assets, enabling you to achieve strategic goals.</p>
