how to fix app service runs out of temp space? - azure-web-app-service

i have isolated i2 service plan the app service runs windows .net web apps .
the local\temp keeps filling up.(I have a process to delete files but it sometimes can't keep up)
should I just attach a azure disk drive "E"?
Or is there a way to increase temp size?

It seems that you can attach a azure disk drive, but according to this post, the disk usage amount seems to be based on SKU. In other words, the higher the SKU level, the larger the disk size that can be used, and the size cannot be specified manually. If possible, you can try to scale to I3.

Unfortunately, you cannot increase the temp folder size inside a App Service. If you wish to increase temp space you can do it by scaling up the app service plan to higher tiers.
The “Disk Space” depends on the App Service plan you're using. It's 1 GB for Free, 10 GB for Basic, 50 GB for Standard and 250 GB for Premium, refer the document for more details on these limits: https://azure.microsoft.com/en-us/pricing/details/app-service/.
App Service also limits the amount of temporary local storage available to each app to prevent individual apps from consuming excessive amounts of local file storage.
Here is the information where you can know about the files that are dealt on Azure WebApp (Persisted files, Temporary files and Machine level read-only files) and there limits as well
Refer the below blog which will help you in understanding the disk space availability

App Service Plan storage increase - Azure

I am learning Azure and I have a question about App Service Plans.
I understand that an App Service Plan has an amount of RAM memory for each virtual machine instance. However, when it comes to storage space, I have a doubt if every time we create a virtual machine instance it is consuming disk space in the plan. For example, I have an application that consumes 1GB with a VM instance. If we scale out this plan and create 3 VM instances, will it take up 3GB of disk space? I understand the instances as copies of the content of the Plan, therefore I understand that for each instance the disk space consumption is multiplied by two. Is that so?
Thank you very much for your responses,
All the best.
SOLUTION
From Azure's own description of its plans, I conclude that each Plan provides ACU, RAM and disk space FOR EACH INSTANCE, not for the total plan.
In the example in the image, each instance has 210 ACUs, 3.5GB of memory and 250GB of storage.
App Service Plan P1V2:

How does Azure distribute memory to apps using the same service plan?

I have created a App Service plan in Azure and under that service plan runs 14 applications.
Now that particular service plan has a pricing tier of Standard and Instance Size of Large, which is S3
S3 Cores: 4 RAM: 7 GB STORAGE:50 GB.
Do these 14 apps share the memory and storage that is available , so only 7G for the 14 apps and 50G of storage for the 14 apps aswell ? If so how can i see how much each is consuming in Azure ?
The short answer is Yes, different plans do exist and if an app is a heavy consumer of vCores or Memory then you should isolate it in its own app service plan. Using the quota option from the app service plan it will show how much in total is used and then separately from each app service you can see their storage quota used as well. Now for CPU or Memory it gets a bit complicated as no straightforward way to see this all-in-one place.

How big a single Azure Function can be?

My Azure Function will require resources to run properly (ranging from 5 to 30 Mb). I'm thinking of putting them on the Blob Storage and loading from the Storage each time function runs, but since it will be quite often (a couple times per day) I'm thinking of simply putting them as resources in the function project.
The question is, how much space can I allocate for the function itself? How big (in terms of disk space) a Azure Function can be?
It depends on which host plan your Function app is on.
For dedicate App service plan(Pricing tier Basic, Standard and so on), we can see the size of disk storage allocated for this plan.
Just like #Slava Utesinov has mentioned, we can also check it from Platform features -> App Service plan -> File system storage as well.
For Consumption plan, File system storage shows 0KB usage among 1GB available. Because Function apps on Consumption plan are stored in Storage File Share, which is specified by WEBSITE_CONTENTAZUREFILECONNECTIONSTRING and WEBSITE_CONTENTSHARE Application settings on Azure portal, check doc. As for space, max size of a File share is 5TB, see doc.

Using Azure Storage Plan with Azure Web App

SUMMARY: Can I use an Azure Storage Plan as additional storage that is available to an Azure Web App?
DETAILS: We have a very simple Web App using a low amount of CPU and large amount of storage (all it does is list and allow you to download files). I need at least 50GB of storage for video and audio files for this app and to get that amount of storage on a plan pushes me up to unreasonable CPU and other resources that I don't need with the consequences of a much higher price.
My plan (hope) is that I could create a Web App and remap the root directory of the Web App to a Storage Plan that is 50GB. Two challenges that I have spent the last day researching but at this point, I have not been able to find an answer.
I have created the Web App. I see that /wwwroot is on the D: drive of the Web App. I also created a storage plan and have created a sharable area of 50GB on the storage plan.
So... Can anyone give me some insight into the following:
How do I tell the Web App to use the 50GB of storage which is now available to it?
How can I map a drive letter to the area in the storage plan?
How do I tell the Web App that it should use the 50GB area on the storage plan as the root drive instead of using D:/Webroot
Many Thanks!
Refer this feedback link on a similar request: https://feedback.azure.com/forums/169385-web-apps/suggestions/13536996-the-ability-to-store-iis-logs-in-azure-file-storag - it has been denied.
By default, on Azure WebApps, all files are stored in the file system with the application, including the media files. You may wish to know about the main types of files (https://github.com/projectkudu/kudu/wiki/Azure-runtime-environment) that are dealt on Azure WebApp (Persisted files, Temporary files and Machine level read-only files)
Refer to the article (https://github.com/projectkudu/kudu/wiki/File-structure-on-azure) File structure on azure to know the sets of files & dirs on Azure WebApp, and check the directories which include the possible increasing files, such as LogFiles, site/repository, site/deployments(for deployment slots) and your directory for uploading files.
To verify you can go to your scm site's debug console
(https://{sitename}.scm.azurewebsites.net/DebugConsole) and query for the free space on d:\local. The “Disk Space” depends on the App Service plan you're using. It's 1 GB for Free, 10 GB for Basic, 50 GB for Standard and 250 GB for Premium, refer the document for more details on these limits: https://azure.microsoft.com/en-us/pricing/details/app-service/.
If your requirement fits you may use ASE - Azure App Service Environment is an Azure App Service feature that provides a fully isolated and dedicated environment for securely running App Service apps at high scale.

According to Microsoft Azure Support:
"... since the Product Group confirmed that it is not possible to mount
additional storage to the web app, you can integrate Azure storage
with the Azure SDK or rest API. But you can't mount the drive and use
it as storage.
Another option that you have would be to replicate the scenario on a
Virtual Machine where you can choose its capabilities (Number of
cores, RAM, and Storage Memory)."
So there you have it. It appears that WebApps are pretty fixed configurations which means that when you scale up a Web App, you get more CPU resources AND more Disk storage. It's a packaged deal most likely designed for ease of deployment. Nothing, it appears, you can do about that.
The best alternative, it seems, is to spin up a VM with your chosen OS and then add additional disk storage as needed. It's a "do-it-yourself" approach but the best solution that seems to be available.

Azure Virtual Machine Billing

I dont know if this is the right place, but I am assuming MSFT staff also answers these questions since the azure portal links to StackOverflow?
Questions:
I understand that Azure no longer bills me for a VM so long as it and its cloud service are stopped. But what is unclear is am I going to be billed for the Cloud Service itself? For example say i create a Virtual machine and by doing so i get a cloud service for it (with ip). Then I turn off that virtual Machine and the cloud service. Do i still get billed for the cloud service even though everything is turned off?
Continuing on the question above. Do i get billed storage fees for the Virtual Machines filesystem. Currently windows vms are around 120GB in size. How does the billing work out for virtual machines? And how does it change if the machine is turned off.
How are Custom Images billed? Say i create my Windows 2012 Master image with IIS and a few other components installed. Then I create my own Image so that I can bring up vms more rapidly. Where is the VM image stored? Will it be in my blob container under VHD's? And again will microsoft charge me to store this image? Will it be the full 120+ GB or the actual size of the image stored.
Sorry to ask these questions. Tried my best to google around and all i could find was a post by Scott Gu where he stated VMs wont be billed and very little detail beyond that.

Essentially think of a cloud service as a shell under which you deploy a VM. Among other things, a cloud service provides you with a DNS (yourcloudservice.cloudapp.net for example). What you get charged for is the VM and not the cloud service so if you have nothing deployed in a cloud service, you don't get charged anything.

Virtual Machines filesystem. Currently windows vms are around 120GB in
size. How does the billing work out for virtual machines? And how does

Yes, I believe so. You would be charged for 120 GB of storage (based on this blog post: http://blogs.msdn.com/b/sql_shep/archive/2013/06/10/azure-billing-per-minute-and-no-compute-charge-for-a-stopped-iaas-vm.aspx) [See my note on pricing below].
How are Custom Images billed? Say i create my Windows 2012 Master
image with IIS and a few other components installed. Then I create my
own Image so that I can bring up vms more rapidly. Where is the VM
image stored? Will it be in my blob container under VHD's? And again
will microsoft charge me to store this image? Will it be the full 120+
GB or the actual size of the image stored.
Custom images are billed in a similar way as standard images as in both cases the VHD file is stored in your blob storage account so Microsoft will charge you for storage. Since VHDs are essentially saved as page blobs and page blobs are only charged based on the bytes occupied you will only be charged for the space you consumed.
UPDATE
VHD Pricing: Essentially VHDs are stored in blob storage as page blobs and the pricing of page blobs is calculated a little bit differently. For page blobs, you're only charged for the bytes you used instead of total blob size. So for example, you have a VHD of 120 GB size (i.e. your page blob size is 120 GB) but you're only occupying 30 GB there, you're only charged for 30 GB and not 120 GB.
As #Gaurav stated, you're not charged for the service container, only for running vm's. In the case of stopped VM's, you won't be charged, although you lose your assigned IP address if you have no other running vm's. You can choose to keep a vm provisioned to preserve IP address but then you'll continue paying for the VM. When a VM is stopped, you'll still pay for its storage (since these are persistent virtual machines).
Regarding storage costs: While the vhd might be a 120GB disk, you only pay for storage that's been actually used. That is, the page blob uses sparse allocation. If you format a 120GB volume but only use 30gb, you're billed for 30gb monthly, not 120gb. You pay for all vhd's, including your custom images, since each is stored in your storage account. Again, you don't pay for 120gb on your custom images; just for the allocated pages.
I don't think you get charged for the OS disk. If you have a data disk then you will be charged for the space used.
