NODEBB: Nginx error performance & High CPU
Solved
Performance

Ok so what value do you advise?
@DownPW you should base it on the output of
ulimit- see belowWith that high value you run the risk of overwhelming your server.

@DownPW And the
worker_processesvalue ? I expect this to be between 1 and 4 ? -
worker_processes auto; -
worker_processes auto;@DownPW ok. You should refer to that some article I previously provided. You can probably set this to a static value.

Ok I will see it for better worker_processes value
I add a rate limite request and limit_conn_zone on http block and vhost block :
– nginx.conf:
http { #Requete maximun par ip limit_req_zone $binary_remote_addr zone=flood:10m rate=100r/s; #Connexions maximum par ip limit_conn_zone $binary_remote_addr zone=ddos:1m; -- vhost.conf : location / { limit_req zone=flood burst=100 nodelay; limit_conn ddos 10; –> I have test other value for rate and burst but they cause problem access to the forum. If you have better, I take it
I add today a proxy_read_timeout on vhost.conf (60 by default)
proxy_read_timeout 180;I have deactivate underattack mode on CF and change for high Level
I have add other rules on CF waf :

@DownPW what settings do you have in advanced (in settings) for rate limit etc?

In cloudflare ?

I wanted to test awstats on virtualmin with root account and it hasn’t updated since August 2022.
I wanted to regenerate the files but I have a problem of rights.
What do you think ? and how t ore-generate a rapport correctly
I would like to use it to better manage the @ips that connect to the server

@DownPW from recollection,
awstatsis accessible via the web front end, so (for example) https://mydomain.com/awstatsHowever, as you are pushing everything into a reverse proxy you’ll need to add a custom route in the
nginx.conffile you are using on the website so this can be rendered outside of NodeBB. -

@DownPW what is the result of disabling it altogether? That will resolve the 503 rate limit error but could we leave the system exposed to bring overwhelmed.

Nope, Awstats is accessible like this via Virtualmin:
I have jsut an error of permission whe nI test to regenerate a Report because the script can’t access to log file

Disabling What ? Traffic management? HSTS ?

No, not at all. That error is because

strange than that.
–> Would you have a solution so that I can regenerate the report and use awstats via virtualmin?

@DownPW try this
https://manpages.org/awstats -
@phenomlab said in NODEBB: Nginx error performance & High CPU:
@DownPW try this
https://manpages.org/awstatsIt worked with the following command (very long) in cli but I’m afraid it won’t work with the virtualmin module
awstats -config=XXX-XXX.XXX -update
