[feature request] Azure Monitor: Metrics collection interval

[vRune4]

Component

Azure.Monitor.OpenTelemetry.AspNetCore

Is your feature request related to a problem?

I am troubleshooting thread starvation issues and I am currently running dotnet-counters in a console trying to capture this data. I have not tried dotnet-counters collect yet since my first thought was to try to collect this information directly to a Azure Log Workspace.

I notice that the PeriodicExportingMetricReader() constructor has an exportIntervalMilliseconds parameter. It would be neat if I could get to that somehow. (I need a sample at least every second)

What is the expected behavior?

A configuration setting for sample interval that allows me to harvest counters more often. Ideally... I need the thread-queue length and thread-count counters for now.

Which alternative solutions or features have you considered?

dotnet-counters collect

Additional context

My initialization code:

builder.Services.AddOpenTelemetry()
		.UseAzureMonitor(opt => { opt.Credential = credential; opt.ConnectionString = appInsightsConnectionString; })
		.WithMetrics(m => { m.AddRuntimeInstrumentation(); });
