You can also have Insights collect **resource utilization metrics,** CPU and memory usage over time, by reading them from Amazon CloudWatch. Utilization data powers the sizing figures in the [Cloud Sizing Compute report](https://support.block64.com/collect-utilization-metrics-from-aws#Xa39a3ee5e6b4b0d3255bfef95601890afd80709), such as **95th CPU %** and **95th RAM %**. Collection is off by default and can be turned on or off at any time without affecting your inventory or connection credentials. > **Note on memory metrics** CloudWatch does not report memory usage for EC2 instances unless the [CloudWatch agent](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Install-CloudWatch-Agent.html) is running on the instance. Instances without the agent will show CPU utilization but a dash (**-**) for RAM. ### Before you begin - Your AWS integration is already connected (see [Integrations : Cloud : AWS](https://support.block64.com/integrations/cloud/aws?hsLang=en)). - **Cost:** metrics are read through Amazon CloudWatch. Depending on the number of instances in your account and your existing CloudWatch usage, enabling collection can affect your AWS bill. See [CloudWatch pricing](https://aws.amazon.com/cloudwatch/pricing/) before enabling. ### Enabling Collection 1. In Insights, go to **Config \> Integrations** and select **AWS**. 2. On the integration page, find the **Collection Settings** card. 3. Switch **Collect Utilization Metrics** on. That’s it, collection starts automatically. Metrics are polled approximately hourly for each instance and retained for 60 days, so the percentile figures in the Cloud Sizing Compute report build up a meaningful picture over the first days and weeks. > **Note** Turning the toggle off stops collection but does not delete your integration credentials or your inventory data. Turning it back on resumes collection. ### Seeing the results Open **Reports \> Cloud Sizing \> Compute**. EC2 instances with utilization data show **95th CPU %** and **95th RAM %** figures, and their **Collector** column shows **Integration**. If the report includes AWS inventory but you see a banner reading *“AWS inventory is included in this report, but resource utilization collection is currently turned off,”* the toggle above has not been enabled for this account.  ### Troubleshooting | Symptom | Likely cause | What to do | | --- | --- | --- | | Toggle is on but the report shows **-** for an instance’s RAM | The instance has no CloudWatch agent, so AWS has no memory metrics | Install the CloudWatch agent, or size on CPU alone | | Toggle is on but CPU figures are also missing | Collection was enabled recently, or metrics are unavailable in the region | Allow a day or two of polling, then re-check | | Report shows inventory but a “collection is currently turned off” banner | The toggle is off for this account | Enable it following the steps above | ### Related Articles - [Utilization Data Collection](https://support.block64.com/utilization-data-collection?hsLang=en) - [Integrations : Cloud : AWS](https://support.block64.com/integrations/cloud/aws?hsLang=en) - [Time Series Data Roll-ups](https://support.block64.com/time-series-data-roll-ups?hsLang=en) - [Getting Started](https://support.block64.com/getting-started?hsLang=en#main-content) - [Free Trial Onboarding](https://support.block64.com/getting-started?hsLang=en#free-trial-onboarding) - [Start Your Subscription](https://support.block64.com/getting-started?hsLang=en#start-your-subscription) - [Discovery Application Installation](https://support.block64.com/getting-started?hsLang=en#discovery-application-installation) - [Discovery Appliance Setup](https://support.block64.com/getting-started?hsLang=en#discovery-appliance-setup) - [Discovery Agent Deployment](https://support.block64.com/getting-started?hsLang=en#discovery-agent-deployment) - [Insights Reports](https://support.block64.com/insights-reports?hsLang=en#main-content) - [IT Asset Management](https://support.block64.com/insights-reports?hsLang=en#it-asset-management) - [Security](https://support.block64.com/insights-reports?hsLang=en#security) - [Cloud & Infrastructure](https://support.block64.com/insights-reports?hsLang=en#cloud-infrastructure) - [The Combine: User Guide](https://support.block64.com/insights-reports?hsLang=en#the-combine-user-guide) - [Troubleshooting](https://support.block64.com/troubleshooting?hsLang=en#main-content) - [Discovery: General Knowledge](https://support.block64.com/troubleshooting?hsLang=en#discovery-general-knowledge) - [Discovery: Block 64 Application](https://support.block64.com/troubleshooting?hsLang=en#discovery-block-64-application) - [Discovery: BlockBox Appliance](https://support.block64.com/troubleshooting?hsLang=en#discovery-blockbox-appliance) - [Discovery: Discovery Agent](https://support.block64.com/troubleshooting?hsLang=en#discovery-discovery-agent) - [Insights Calculations](https://support.block64.com/troubleshooting?hsLang=en#insights-calculations) - [Documentation](https://support.block64.com/documentation?hsLang=en#main-content) - [Discovery: General Knowledge](https://support.block64.com/documentation?hsLang=en#discovery-general-knowledge) - [Privacy and Security](https://support.block64.com/documentation?hsLang=en#privacy-and-security) - [Block 64 API](https://support.block64.com/documentation?hsLang=en#block-64-api) - [Integrations](https://support.block64.com/documentation?hsLang=en#integrations) - [FAQs](https://support.block64.com/faqs?hsLang=en#main-content) - [Security](https://support.block64.com/faqs?hsLang=en#security) - [Block 64 Discovery](https://support.block64.com/faqs?hsLang=en#block-64-discovery) - [New Features & Updates](https://support.block64.com/new-features-updates?hsLang=en#main-content) - [New Features & Updates](https://support.block64.com/new-features-updates?hsLang=en#new-features-updates) - [Combine](https://support.block64.com/new-features-updates?hsLang=en#combine) - [Block 64 Discovery](https://support.block64.com/new-features-updates?hsLang=en#block-64-discovery) - [Remote Discovery Agent](https://support.block64.com/new-features-updates?hsLang=en#remote-discovery-agent) - [Combine API](https://support.block64.com/new-features-updates?hsLang=en#combine-api) - [BlockBox Virtual Appliance](https://support.block64.com/new-features-updates?hsLang=en#blockbox-virtual-appliance) [![Logomark - dark](https://support.block64.com/hs-fs/hubfs/Logomark%20-%20dark.png?width=60&height=96&name=Logomark%20-%20dark.png "Logomark - dark")](http://block64.com) 300 Geary Ave, Toronto, ON M6H 2C5, Canada +1 800-875-5260 [www.block64.com](https://www.block64.com/)
