# Azure Web App Resource Exhaustion Issue
---

The Azure Web App Resource Exhaustion Issue occurs when a web app exhausts its allocated resources (CPU, memory, etc.), leading to performance issues. This can be resolved by either scaling up the App Service plan to a higher SKU or identifying performance bottlenecks using application insights and optimizing the code.

### Parameters
```shell
export RESOURCE_GROUP_NAME="PLACEHOLDER"

export APP_SERVICE_PLAN_NAME="PLACEHOLDER"

export APP_SERVICE_PLAN_ID="PLACEHOLDER"

export WEB_APP_NAME="PLACEHOLDER"

export NEW_SKU_NAME="PLACEHOLDER"

export APP_INSIGHTS_NAME="PLACEHOLDER"

export APP_INSIGHTS_ID="PLACEHOLDER"

export LOCATION="PLACEHOLDER"
```

## Debug

### Get the details of the affected web app
```shell
az webapp show --name ${WEB_APP_NAME} --resource-group ${RESOURCE_GROUP_NAME}
```

### Get the current App Service plan SKU
```shell
az appservice plan show --resource-group ${RESOURCE_GROUP_NAME} --name ${APP_SERVICE_PLAN_NAME} --query "sku.name"
```

### Get performance metrics for the web app
```shell
az monitor metrics list --resource ${APP_SERVICE_PLAN_ID} --metric "CpuPercentage" "MemoryPercentage" --interval 5m
```

### Check Application Insights is configured for the web app
```shell
az webapp config appsettings list --name ${WEB_APP_NAME} --resource-group ${RESOURCE_GROUP_NAME} | grep -i applicationinsights
```

### Identify performance bottlenecks using Application Insights
```shell
az monitor app-insights query --apps ${APP_INSIGHTS_ID} --analytics-query "requests | summarize count(), avg(duration) by operation_Name"
```

### Create and Connect Application Insights for the web app
```shell


#!/bin/bash



# Set variables

RESOURCE_GROUP=${RESOURCE_GROUP_NAME}

WEB_APP_NAME=${WEB_APP_NAME}

APP_INSIGHTS_NAME=${APP_INSIGHTS_NAME}

LOCATION=${LOCATION}



# Create Application Insights

az monitor app-insights component create --app $APP_INSIGHTS_NAME \ 

    --resource-group $RESOURCE_GROUP \

    --location $LOCATION



# Connect Application Insights to the Web App

az monitor app-insights component connect-webapp --resource-group $RESOURCE_GROUP \

 --app $APP_INSIGHTS_NAME \

 --web-app $WEB_APP_NAME --enable-profiler --enable-snapshot-debugger



# Verify connection

az webapp config appsettings list \

    --resource-group $RESOURCE_GROUP \

    --name $WEB_APP_NAME \

    --query "[?name=='APPLICATIONINSIGHTS_CONNECTION_STRING']"


```

## Repair

### Scale up the App Service plan to a higher SKU: This involves increasing the resources allocated to the web app, such as CPU and memory. This can be done through the Azure Portal or programmatically using Azure CLI or Azure PowerShell.
```shell
bash

#!/bin/bash



# Set variables

RESOURCE_GROUP=${RESOURCE_GROUP_NAME}

WEB_APP_NAME=${WEB_APP_NAME}

PLAN_NAME=${APP_SERVICE_PLAN_NAME}

NEW_SKU=${NEW_SKU_NAME}



# Scale up the App Service plan to a higher SKU

az appservice plan update --name $PLAN_NAME --resource-group $RESOURCE_GROUP --sku $NEW_SKU



echo "App Service Plan $PLAN_NAME has been scaled up to $NEW_SKU for $WEB_APP_NAME web app."
