what is the better solution for Performance counter Error on application Insights?

AI: Error collecting 3 of the configured performance counters. Please check the configuration. Counter \ASP.NET Applications(??APP_W3SVC_PROC??)\Requests/Sec: Failed to perform the first read for performance counter. Please make sure it exists. Category: ASP.NET Applications, counter: Requests/Sec, instance example.exe Counter \ASP.NET Applications(??APP_W3SVC_PROC??)\Request Execution Time: Failed to perform the first read for performance counter. Please make sure it exists.

Probably those counters are not available on the platform or hosting option of your app.

For .Net Core

You can disable collecting them at all like this:

        public void ConfigureServices(IServiceCollection services)
        {
            ...

            services.AddApplicationInsightsTelemetry(options =>
            {
                options.EnablePerformanceCounterCollectionModule = false;
            });
            ...
        }

or you can remove (or add) counters like this:

        public static void Configure(IApplicationBuilder app)
        {
            ...
            var modules = app.ApplicationServices.GetServices<ITelemetryModule>();
            var perfModule = modules.OfType<PerformanceCollectorModule>().FirstOrDefault();
            if (perfModule != null)
            {
                perfModule.DefaultCounters.Remove(perfModule.DefaultCounters.First(dc =>
                    dc.PerformanceCounter == @"somecounter"));
            }
            ...
        }

For Asp.Net

Edit your applicationinsights.config file and remove the counters that give errors / you don't want:

<TelemetryModules>
    ...
    <Add Type="Microsoft.ApplicationInsights.Extensibility.PerfCounterCollector.PerformanceCollectorModule, Microsoft.AI.PerfCounterCollector">
        <DefaultCounters/>
        <Counters>
            <!--<Add PerformanceCounter="\Process(??APP_WIN32_PROC??)\% Processor Time" ReportAs="\Process(??APP_WIN32_PROC??)\% Processor Time" />
                <Add PerformanceCounter="\Process(??APP_WIN32_PROC??)\% Processor Time Normalized" ReportAs="\Process(??APP_WIN32_PROC??)\% Processor Time Normalized" /> -->
            <Add PerformanceCounter="\Process(??APP_WIN32_PROC??)\Private Bytes" ReportAs="\Process(??APP_WIN32_PROC??)\Private Bytes" />
            <Add PerformanceCounter="\Memory\Available Bytes" ReportAs="\Memory\Available Bytes" />
            <Add PerformanceCounter="\Process(??APP_WIN32_PROC??)\IO Data Bytes/sec" ReportAs="\Process(??APP_WIN32_PROC??)\IO Data Bytes/sec" />
            <Add PerformanceCounter="\Processor(_Total)\% Processor Time" ReportAs="\Processor(_Total)\% Processor Time" />
        </Counters>
    </Add>
    ...
</TelemetryModules>
