503 error: high level traffic

[baris]

How many nodebb processes are you running? What does the cpu/ram usage look like on your server?

[DownPW]

@baris

Default configuration for nodebb.

One node process
50% CPU - 85 % RAM

I will test to scale nodeBB tonight with redis and instruct NodeBB to run on multiple processes by adding the port property into your config.json
but I wanted to know if we could play with its values ​​and which ones adopted

@DownPW yes, this is the place to start

Scaling - NodeBB Documentation

Documentation portal for NodeBB Forum Software

(docs.nodebb.org)

[DownPW]

I have done the nodebb scaling tonight (many thanks for your help @phenomlab always )and we have upscale the VCPU for 4 core and scaling RAM (8Gb)

So, 3 process for nodeBB with redis.

It's better but we have sometimes 503 nodebb error when we have a lot of users (1.1K actually) and lot of posts/participation.

Maybe we can optimize more ? With traffic management option values ? or disable it ?

We have sometimes this error, what do you think about it ?

[crazycells]

@DownPW these are our values:

I guess you can increase the "check interval" first, and see if it improves.

[baris]

Also monitor your server and make sure the 3 nodebb processes are all getting traffic. There is a page in the ACP(admin/development/info) that can show this info as well.

[DownPW]

Yep @baris

here is the info :

I see CPU usage on all process but I see this also :

Thanks @crazycells

I will test test to increase the Check Interval

[phenomlab]

@baris very odd. I too am using clustering and I do not see any reference in the ACP for admin/development/info ??

EDIT - Typed the URL manually and it works, but I see the same as @DownPW

[baris]

That looks correct only one nodebb process should have /

[crazycells]

@baris said in 503 error: high level traffic:

admin/development/info

is this link hidden?

I could not see it on the ACP either, but I typed it manually and can see all three ports, and only one has check mark next to it.

[baris]

Yeah it doesn't have a link in the ACP, it's a page.
