application insights not showing request data

Hi,

Our application insights for azure function have stopped showing data such as "Requests" , only telemetry we can see is "Trace"
here is the host.json we have:
{
"version": "2.0",
"extensions": {
"http": {
"routePrefix": ""
}
},
"logging": {
"logLevel": {
"default": "Information",
"Host": "Error",
"Function": "Error",
"Host.Aggregator": "Error"
}
}
}

@ChenLiang-4493 , You dont see any other traces apart from "Request successfully matched the route with name 'auto' and template" ?

Hi @ChenLiang-4493 ,

Thanks for reaching out to Q&A.

Log sampling may cause some executions to not show up in the Application Insights blade. To avoid log sampling, add excludedTypes: "Request" to the samplingSettings value

Please modify the host.json in the following way and check if the issues is resolved.

{
"logging": {
"applicationInsights": {
"samplingSettings": {
"isEnabled": true,
"maxTelemetryItemsPerSecond" : 20,
"excludedTypes": "Request;Exception"
}
}
}
}

Reference : https://docs.microsoft.com/en-us/azure/azure-functions/configure-monitoring?tabs=v2#configure-sampling

I hope this helps! Feel free to reach out to me if you have any further queries or concerns.
