[edx-code] EDX Server Capacity Planning

[Neville D'Souza]

Hi All,

I was trying get an answer to my query about server capacity planning for 
production. I would like to know hardware required for 500 concurrent 
users. I would like to have 2 server setup. One for LMS/CMS/DB and other 
for Insights. Does anyone know of a guide to help anyone to understand 
hardware requirements? What are the parameters that decide the CPU/Disk and 
Memory? I read in this forum someone saying 1 GB RAM for 70 concurrent 
users. Any help would be great.

Regards,
Neville

[edx-code] Instructor bulk emails failing

[Neville D'Souza]

Hi All,

I have been having issues with instructor bulk emails. I have emails setup 
with mandrill which works for enrollments. But for instructor emails I get 
a from email address like pdwdm1-no-re...@example.com 
 which 
was getting rejected by mandrill.So I changed the email 
address "BULK_EMAIL_DEFAULT_FROM_EMAIL": "cour...@somedomain.com", in 
lms.env.json and cms.env.json . I restarted nginx, edxapp and edxappworker 
services and emails stopped going out completely. Even after a reboot still 
the same.

I basically want to send the mails from cour...@somedomain.com instead of 
email address with course abbreviation in front which makes it a fake 
address and get blocked by sending services. Has anybody had success doing 
this? If anyone from edx is looking at this please note this fake email 
creation is a problem because most services now will not accept fake 
address and think of it as spam.

Neville

[edx-code] Re: Configure bulk emails

[Neville D'Souza]

Hi Liubov,

Are you aware how to change the sending email address without abbreviation 
in front to a proper email address set in "BULK_EMAIL_DEFAULT_FROM_EMAIL": 
"cour...@somedomain.com", ?

[edx-code] Upload SGA and grades attachments on S3

[Neville D'Souza]

Hi All,

I am hoping someone can help with moving SGA and grades uploads from local 
to S3. We are using the same version of SGA that came with Ficus.4 version 
of edx.

So far i have done the below

sudo vi /edx/app/edxapp/lms.auth.json
"AWS_ACCESS_KEY_ID": "xxx",
 "AWS_SECRET_ACCESS_KEY": 
"xx",
 "AWS_STORAGE_BUCKET_NAME": "edxbucket",

But it is still getting uploaded on local storage. I am guessing its 
because of below. But what do I change this to work with S3 storage.

sudo vi /edx/app/edxapp/lms.env.json
sudo vi /edx/app/edxapp/cms.env.json
"DEFAULT_FILE_STORAGE": "django.core.files.storage.FileSystemStorage",
"MEDIA_ROOT": "/edx/var/edxapp/media/",
"MEDIA_URL": "/media/",

I must say i have ORA2 files uploaded on S3 storage but grades attachments 
uploaded locally. I would like to upload grade attachments on S3 storage as 
well. Any help with SGA and grades attachments upload to s3 would be 
helpful.

For grades would the below be correct

Inside lms.env.json & cms.env.json


"GRADES_DOWNLOAD": {

"BUCKET": "",

"ROOT_PATH": "",

"STORAGE_CLASS": "django.core.files.storage.FileSystemStorage",

"STORAGE_KWARGS": {

"location": "/tmp/edx-s3/grades"

},

"STORAGE_TYPE": ""

change to

"GRADES_DOWNLOAD": {
"BUCKET": "edxbucket",
"ROOT_PATH": "edxbucket/grades",
"STORAGE_TYPE": "s3"
},

Regards,
Neville
