Our official Docker container ships with a custom NGINX config that logs very rich information that can be used to debug server performance issues.

To achieve rich diagnostics, Discourse add 2 additional headers to all requests in application_controller.rb

 def set_current_user_for_logs
    if current_user
       Logster.add_to_env(request.env,"username",current_user.username)
       response.headers["X-Discourse-Username"] = current_user.username
    end
    response.headers["X-Discourse-Route"] = "#{controller_name}/#{action_name}"
 end

Furthermore we define a custom NGINX log format:

log_format log_discourse '[$time_local] $remote_addr "$request" "$http_user_agent" "$sent_http_x_discourse_route" $status $bytes_sent "$http_referer" $upstream_response_time $request_time "$sent_http_x_discourse_username"';

This means that we track: User Agent, Duration, Status, Rails Duration, Referer and more for every request.

Out of the box NGINX does not log the time it spends in the "upstream" proxy, this is added to our logs using $upstream_response_time

Given this rich information I took a stab at creating a "reporting tool" that analyzes the logs and gives you some interesting reports, the tool is early in development, but already useful: https://github.com/discourse/discourse/blob/master/script/nginx_analyze.rb

To run it (you will need to be on a very recent install, you must rebuild to update NGINX config):

cd /var/discourse
./launcher enter app
cd /var/www/discourse/script
ruby nginx_analyze.rb

The report provides the following:

Overview of request counts for the duration of the log

Total Requests: 11105 ( MessageBus: 6757 )

We can see that we processed 11105 requests total, 6757 were consumed by message_bus. To learn more about message bus see this post or search meta

Top 30 IPs by server load

Which IPs are responsible for the largest amount of CPU time?

IP Address       Duration
----------       --------
100.43.90.12        16.71
10.66.0.21           7.45
10.66.0.22           7.31
... etc ...

So in the above we can see that Yandex crawling is causing a fair amount of load. As well as a couple of private IP addresses.

Top 30 Users by Server Load

Username     Duration
--------     --------
[Anonymous]    120.26
codinghorror     2.78

It looks like me and @codinghorror are responsible for a bit of load here

Top 30 routes by Server Load

list/category_latest            0.98
topics/feed                     0.97

This information is particularly useful for quite a few reasons and can be used for diagnostics.

Routes at the top of the list are ones that have the most impact on global performance so it makes sense for us to focus on improving them (or cutting down calls to them) first.

This shows us which URL are responsible for the most amount of load on the server. Perhaps there is a topic that has performance issues? Perhaps there is a page that is visited too often by bots?

Hi All,

I'm new here, and we are excited to be joining the discourse community!

We are trying to implement a landing page similar to the smartthings community (http://community.smartthings.com/) We are trying to create a landing page carousel that only shows on the landing page, the carousel works great. Just trying to figure out how smartthings made their's only appear on the main page and not in the category pages.

Any help would be much appreciated! I can PM our sandbox info if you need it.

aaaaaaaaaaaaaaaaaaaa

Middle-clicking each one opens the numbered post in t/1000, as expected.
Left-click should do the same, right? Er, no; instead, the 1000 is treated as if it's the slug, and removed. The post number is then misinterpreted as the topic number.

OK, there's no t/1000 here, but it's the URL treatment that's important.

Edit: Interesting… can't reproduce it here…

Update: OK, try this one: [link](/t/1000/29066) link << That one triggers the bug

Continuing the discussion from The Official Discourse Tags Plugin: discourse-tagging

Wonder if anyone else agrees it would be handy to be able to track categories or tags and just be notified when a new topic is posted in one.

So for example on a dog breed forum you get a notification when a topic is posted about a certain breed of dog (the tag). Or on a gaming site you get notified when a topic is posted about a certain game (the tag) you might be following and interested in. People can then review the topic/thread and decide whether they want to watch or track it.

On Xenforo there is this - which I think works really well:

So multisite confuses you, and you got the memory to dish out?

This guide is a how-to for people who can't quite wrap their heads around multisite, but need to have... multiple sites! Easy peasy.

Assumptions

• you've got multiple subdomains pointed to your server IP
• you've got at least 1 gig for each site in combined memory and swap
• you have root access to install new apps
• you're already familiar with docker and basic standalone setup
• currently on ubuntu 14.04 64bit

Okay, with that out of the way, lets move forward.

You'll need to setup nginx as a reverse proxy so that you can have the multiple web apps running through the same http port externally (80 or 443), assuming this is http, this is how it'll work out..

Install nginx

apt-get install nginx

zoom to the correct directory and download this snippet into it, rename appropriately

cd /etc/nginx/sites-enabled
wget https://gist.githubusercontent.com/trident523/ee1be110212b4a7a1291/raw/9415a7f2e9bfd84a1c8857e17686bd526d4e652f/discourse.conf
mv discourse.conf anyname.conf
cp anyname.conf anyother.conf
nano anyname.conf anyother.conf

so you should see a file like this:

https://gist.githubusercontent.com/trident523/ee1be110212b4a7a1291/raw/9415a7f2e9bfd84a1c8857e17686bd526d4e652f/discourse.conf

upstream discourse {
#fail_timeout is optional; I throw it in to see errors quickly
server 127.0.0.1:4578 fail_timeout=5;
}

# configure the virtual host
server {
# replace with your domain name
server_name discourse.example.com;

location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
# pass to the upstream discourse server mentioned above
proxy_pass http:// discourse;
}
}

You need to change the bold. Starting at the top, the two copies need to be differentiated. You can use discourse1, and discourse2, or whatever else.

The port can be ascending, so 4578, and 4579 will work.

The servername is the same name as you will configure in the app.yml files. These are the same as you will create the a-record with the hosting company. we'll use discourse1.example.com and discourse2.example.com.

So then the end result would be this:

upstream discourse1 {
#fail_timeout is optional; I throw it in to see errors quickly
server 127.0.0.1:4578 fail_timeout=5;
}

# configure the virtual host
server {
# replace with your domain name
server_name discourse1.example.com;

location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
# pass to the upstream discourse server mentioned above
proxy_pass http://discourse1;
}
}

upstream discourse2 {
#fail_timeout is optional; I throw it in to see errors quickly
server 127.0.0.1:4579 fail_timeout=5;
}

# configure the virtual host
server {
# replace with your domain name
server_name discourse2.example.com;

location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
# pass to the upstream discourse server mentioned above
proxy_pass http://discourse2;
}
}

Now nginx is setup, awesome.

Do you already have an app.yml? If so, you just need to copy a second one and differentiate some things in the file, if not:

cd /var/discourse
cp /samples/standalone.yml /containers/discourse1.yml
cd containers
cp discourse1.yml discourse2.yml
nano discourse1.yml discourse2.yml

now we need to change some settings inside the containers

look for this part:

You see those ports? Change the outgoing http port to 4578 on the first container, and 2222 for ssh. The next container after you close this file make it one up, 4579, and 2223

If you recall there is section to fill in the basics, including hostname. This is where you match what you choose for the subdomains with your a-records, and the nginx config files earlier. We are using discourse1.example.com, and discourse2.example.com here.

The only other differentiation is the volumes section below the standard configs. Check it here:

you see where I added an additional folder layer after shared? That's all there is to it. You can make this the hostnames, or ports, I suggest hostnames.

After you have edited both yaml files, you can do the regular

cd ..
./launcher bootstrap discourse1 && ./launcher start discourse1
./launcher bootstrap discourse2 && ./launcher start discourse2

The last step would be to start the nginx service

service nginx restart

if fail, check

nginx -t

and solve issue.

Now, that wasn't so painful, was it?

Hello everyone

TL;DR
I want to know how I can add a custom function to the topic list view and call it from the topic list template.

---

I'm developing an up/down voting plugin (I know...) and I've already implemented an initial and static UI:

Screen Shot 2015-06-17 at 7.09.15 PM.png2272x940 212 KB

For now, I've added some HTML + CSS to the topic-list-item.raw.hbs

I've also successfully added and configured the ActiveRecord Reputation System gem. So I already can (programmatically) vote up/down on Topics.

Now I just need to make the up and down buttons work (of course! ).

---

The issue is that I cannot add any helpers to the template. I think the reason is because it's a raw.hbs file. So I can't add the {{action}} or the {{view}} helpers.
And I don't even know if making one of them work would be the ideal approach.

I'm aware of the initialize function using reopen in order to change a view.
So I'm thinking in being able to call, from the template, a custom function that I'll add to the discourse/topic-list-item view.
Is that possible and the best approach? If so, how can I do that?

---

I need this current step to be built in a way where I can, as a next step, call/request (or read) the voting score and display/toggle a class if the current user has already voted on the topic (just like the heart button does).

Thank you very much for your attention!

Bonus question: How can I avoid having to ./launcher rebuild app (and wait several minutes) every time I change something on my plugin code?

NOTE: I solved my problem via rails console, however it would be MUCH easier if it was possible to do this in the interface.

I've got a user that has registered an account on my system, but they have typo'd their email address. I know this because I got a delivery failure message, and noticed the typo in the domain causing the problem. I thought it would be a simple matter to go in to the interface to edit the email address and re-send the activation email, however it seems that it is impossible to do so.

Searching meta led me in the direction of a convoluted method of either impersonating the user, or editing the email on their public profile. However, since the user has never logged in. the buttons to impersonate or view the public profile don't exist.

I don't think simply deleting the user and expecting them to figure out why they never received an email is the correct approach.

It is strange to me that as an admin, I can change the username and other settings of a user's profile from the admin page, but I can't do something as basic as editing their email address. - Perhaps there's some philosophy behind this choice that I'm missing.
