Disable health-check logging in AWS ELB Django Application

Question

I have a Django application running on aws-elastic-beanstalk. I try to disable the logs caused by my health-checks. The health-checks are already routed to a seperate page.

Elastic-beanstalk uses Apache + mod_wsgi.

Here is a solution that works with nginx servers. I try to create something similar for apache.

I found out that conditional Logs are probably the appropriate way to do it with an Apache Server.

My directory struture looks like the following

/etc/httpd/ - conf - httpd.conf # main conf - conf.d - wsgi.conf # virtual hosts - additional config files 

my attempt:

files: "/etc/httpd/conf.d/disable_health_logs.conf": mode: "000644" owner: root group: root content: | <IfModule mod_setenvif> SetEnvIf Request_URI "^/health/$" dontlog CustomLog logs/access_log combined env=!dontlog </IfModule> 

The additional config disable_health_logs.conf is created but it has no effect. Neither do I see error logs nor a change in the access logs.

In the httpd.conf there is already the following setting:

 CustomLog "logs/access_log" combined 

Do I need to override it?

Answer 1

I assume you are loading the module somewhere with the following

LoadModule setenvif_module <your_apache_modules_path>/mod_setenvif.so 

Also, need to correct your IfModule as shown below (note: the .c at end)

<IfModule mod_setenvif.c> SetEnvIf Request_URI "^/health/$" dontlog CustomLog logs/access_log combined env=!dontlog </IfModule> 

What you have looks correct otherwise.

Answer 2

So I had another go on this.

The problem really is the setting in the httpd.conf. If I outcomment the line:

#CustomLog "logs/access_log" combined 

manually via ssh my settings are used and the health-checks disappear from the logs.

Note that this is not really a permanent solution as beanstalk might spin up a new instance and override the httpd.conf again
