i have the following issue:
Want to copy xls file from sharepoint to adls via logic apps, but unfortunely receiving the following message (below image):
configured maximum buffer size
So is there any solution to solve this problem?
Thank you
That file is bigger than the limit (here)
Some tasks support chunking. that SharePoint one does not. Http will do (here)
so, you can try using http to invoke graph

I have azure log files with more than 250MB size each in one container(6 files per hour). I have cs program to access and process these log files. But what i am doing now is just taking only 100 lines from each log files(created in one hour). If i am processing the whole files, then i want to access almost 1.5GB of data. How can i handle this situation? My plan is to use a WebJob to create smaller files from this log files automatically and to store these files to a different container, and access that files from my cs program. Do you have any idea?
To tell the truth I don't understand the problem- are you worried because of traffic or processing time?
In any case you can try to reduce file size by removing some fields in IIS log setup. Another option will be setting Log File Rollover to smaller size- this can minimize download time for processing.
What you are suggesting is doable with a WebJob, but it sounds like the size of the file is the issue. Would a different log type be better for your scenario? Possibly using "Failed Request Tracing". You may also be able to change the verbosity level in the diagnostics config. For more info see:

I have an application which creates the URL and sends a post request to server using IIS.
As per the microsoft library, maxallowedcontentlength is 4GB. But I want to store files more than 4GB, max size will be around 40GB.
Is there any approach to perform this task ?
Any help is highly appreciated.
Thanks. .
Try to split the file in parts,if you can
I'm trying to create an app which uses Windows Media Services REST API to upload video files and transcode them. Everything works great but i have encountered a situation, in which i'm not able to upload a 160 MB video file without knowing why. It's extremely painfull to debug the upload process in a regular way cause uploading 160 MB file takes ages so i decided to ask my question here:
I know about Azure Storage limitations of single file size (which is up to 64 MB). Is there such limitation for uploading files to Windows Media Services as well? Do i need to send that file in 4 MB chunks?
If so, how can actually do that using REST API ? I can send chunked file to a regular storage account but, when it comes to WMS, things are a bit different. Basically, when dealing with WMS, i need to upload my file (or file blocks) to a specific temporary url and i'm not sure how to combine that with chunks and setting a block id etc. I also can't find any info about that on the internet.
Thanks in advance for any advice!
You didn't say which platform are you using to build your application (I'm guessing it's .net?)
According to MSDN, single file (blob) is not limited to 64 MB:
Each block can be a different size, up to a maximum of 4 MB. The maximum size for a block blob is 200 GB, and a block blob can include no more than 50,000 blocks. If you are writing a block blob that is no more than 64 MB in size, you can upload it in its entirety with a single write operation.
This means you can upload files (blobs) which are up to 200 GB. If file is smaller than 64 MB, you can upload it as one big chunk (block). If it's bigger than 64 MB, you will have to split it into smaller blocks (up to 4 MB each) and upload it that way.
Full disclosure: I wrote this blog post which explains how to build an async upload page which can upload files in chunks. It uses the Azure REST API to upload all the file blocks and the Windows Azure Media Services SDK to communicate with the Media Service and create locators (temporary URL's you mentioned) which are used to upload files.
There is quite a bit of code involved in making this work so I created a simple demo app (written in JS and .net) to go together with the post. If you're not doing this in .net, you will still be able to use the JS portion of the code, it's just that you'll need to obtain the upload locators through Azure REST API as well.
Very simplified, the upload/transcoding workflow goes something like this:
Obtain a temporary upload URL (locator) through the back-end of your application (to secure your Azure credentials)
Split a file into smaller chunks, upload them all to Azure storage on behalf of WAMS (Windows Azure Media Services) through the REST API while keeping track of all block ID's
Submit an XML containing all block ID's to the REST API
If needed, transcode videos (I used the WAMS SDK in the back-end of the app to create the encoding jobs) - each video will be a new separate Asset
Publish assets - get locators (URL's) for accessing the original and/or transcoded videos
I also recommend you read Gaurav Mantri's post about uploading large files to Azure storage. It explains a lot and is a very good read about this topic.
Does it make sense that IIS will become extremely slow and unresponsive when using IIS Advanced Logging to log all incoming requests?
I have some rules that divide the incoming requests into 5 files according to their prefix. I found out that a simple stress test of 100 users sending requests nonstop for half an hour. The IIS process memory goes all the way up to 4GB and won't recycle at 500MB limit.
Thanks!
It sounds like there are two separate issues here.
1) IIS does not seem to be respecting the Application Pool Recycling criteria when a process exceeds a specified working set
2) IIS Advanced Logging seems to be consuming large amounts of memory given this configuration.
Regarding #2 - one suggestion is to start by disabling filtering and writing to a single log to see if that alleviates the memory consumption issue. If you don't mind sharing the relevant snippets of the applicationHost.config and/or web.config files that contain your Advanced Logging settings and log definitions, that would be very helpful for repro'ing the issue.

Was the data written to the files correctly when not under load? Also, was the 500MB limit per log?
When people download files from my website, I don't want them to be able to download faster than 300KB/sec per file.
Is there anyway to do this? I'm running IIS 6.0 on Windows Server 2003.
You can't limit download speed but you can limit the overall traffic to a particular website:
Open IIS MMC
Select Website
Select Performance tab
Enable 'Bandwidth throttling'
Write a script that transfer the data in chunks. After 300KB you wait until 1 seconds is consumed.
I just found this but I haven't had time to try it out myself IIS Bit Rate Throttlling
I agree with Horcrux (cant vote it as dont have enough rep)
if the file is less than 300KB, then this wont work,
but for large files, then adverage over the course of the whole file download will be
300Kbps...
I'm assuming the idea is like a rapidshare idea, premium users will have full speed downloads?
Also, while one thread(user) is waiting for a second, another thread can be downloading.
Queue the downloads, and only let X amount run at the same time, and your away in a hack!
Within website properties in IIS 6.0 there is a Performance tab and the first setting is Bandwith throttling which allows you to set the maximum bandwidth value in kilobytes per second. It also has this note;
For bandwidth throttling to function, IIS needs to install Windows Packet Scheduler.
I'm guessing using this setting would mean having your downloads on a separate site so you can throttle that but maintain full bandwidth to your normal content.
For IIS 10, go to IIS Manager and you will find a your setting under the header
Media Services > Bit Rate Throttling
Reduce the speed of you Internet connection.
