[BUG] Live Metrics inaccurate CPU display

[vRune4]

Library name and version

Azure.Monitor.OpenTelemetry.AspNetCore 1.2.0

Describe the bug

CPU usage is suspiciously low. It rarely passes 25%.

If I later visit the container's own metrics it shows closer to 80%:

Expected behavior

Live Metrics should show higher CPU usage.

Actual behavior

The live CPU meter rarely ventures above 25%.

Reproduction Steps

1. Create container app
2. Program.cs: builder.Services.AddOpenTelemetry().UseAzureMonitor(opt => { opt.Credential = credential; opt.ConnectionString = appInsightsConnectionString; });
3. Hammer container with thousands of requests, as much as it can handle... (but not much more than that)
4. Compare what Live Metrics observed with what the container's own Metrics shows afterwards.

Environment

asp.net 9
azure container apps
