Workspace Weekly: Platform Metrics – Correlate Infrastructure with Test Results
January 22, 2026
Testing tells you what happened. Infrastructure metrics tell you why it happened.
Platform Metrics in Login Enterprise lets you bring external measurements like GPU latency, hypervisor CPU, storage IOPS, network throughput into the same view as your test results.
Instead of searching through dashboards or guessing which infrastructure event lined up with a performance drop, you can see the cause of the issue clearly.
If you run tests on Nutanix, VMware, Azure, or any platform that exposes performance data via API, Platform Metrics gives you a place to land that data alongside Login Enterprise sessions, response times, and EUX scores.
What it means for you
Platform Metrics is an ingestion point. You send time-stamped measurements from your infrastructure into Login Enterprise, and those data points show up in test results as charts you can compare against application performance, user experience scores, or session timelines.
That means:
- One place to correlate infrastructure behavior with user experience metrics.
- Faster troubleshooting when performance dips because you can see platform load at the exact moment.
- Better root cause analysis without switching between tools or exporting data to spreadsheets.
How it works
Platform Metrics uses the Login Enterprise API to accept external measurements. Your infrastructure, whether that’s a hypervisor, GPU monitor, storage array, or custom script sends metric data to the Platform Metrics endpoint with a timestamp and value.
Login Enterprise stores it and displays it in the test result interfaces.
To view Platform Metrics charts in the Login Enterprise web UI, you’ll need to enable the feature flag in your browser console. Open Developer Tools (F12), navigate to the Console tab, and run:
leSetFeatureFlag(‘platformMetrics’, 1)
Refresh the page, and Platform Metrics charts will appear in your Continuous Test and Load Test results.
From there, you can overlay infrastructure metrics against Login Enterprise measurements to see how platform resource consumption lines up with session responsiveness or application lag.

Imagine if you are…
Running a Continuous Test with 50 sessions and notice response times spike at 2:47 PM.
You flip to Platform Metrics and see GPU memory usage jumped from 60% to 95% at 2:46 PM.
Now you know the spike wasn’t an application bug or network issue. GPU contention was the cause of the spike. You report it to infrastructure; they tune GPU allocation, and the next test runs clean.
Or imagine you’re validating a new Nutanix cluster before go-live. You run a Load Test while sending cluster CPU, memory, and storage IOPS to Platform Metrics. The test completes, and you pull up the results.
EUX scores dropped during ramp-up, and Platform Metrics shows storage latency spiked at the same moment. Now you can tune storage QoS and retest with confidence.
See it in action with NVIDIA nVector
If you want a working example of Platform Metrics, check out our NVIDIA nVector integration. It measures endpoint GPU latency during Login Enterprise tests and uploads that data to Platform Metrics. This way you can see graphical responsiveness alongside session metrics.
The nVector integration is live and documented here: NVIDIA nVector Integration. It’s a good reference if you’re building your own Platform Metrics integration and want to see how another system sends data to Login Enterprise.
For the full technical setup, scripts, and PDF guide, visit the GitHub repo: LoginVSI/nVector. It’s a bit more technical, but useful if you want to model your own integration.
What’s next
Platform Metrics has been available for about a year, and we’re working on improvements for future releases. Keep an eye on release notes and upcoming Workspace Weekly articles for updates on charting, usability, and new integration examples.
If you’re already using Platform Metrics or building an integration, we’d love to hear what’s working and what you’d like to see next.
As always, thank you for your feedback! We use your insights to make Login Enterprise better for you. Stay tuned for more Workspace Weeklies, and join our Slack channel #workspace-weekly to share field stories, tips, and interesting finds.
