Disable debug output to debug.log

[viktor-zhuromskyy]

Can't figure out how to disable debug output to debug.log for things like cache invalidation, etc. In production mode this information is not necessary to log.

[2016-05-01 02:17:20] main.DEBUG: cache_invalidate: {"method":"GET","url":"https://endohaus.com/checkout/cart/","invalidateInfo":{"tags":["rewards_purchase"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:17:20] main.DEBUG: cache_invalidate: {"method":"GET","url":"https://endohaus.com/checkout/cart/","invalidateInfo":{"tags":["rewards_purchase_55","rewards_purchase"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:17:20] main.DEBUG: cache_invalidate: {"method":"GET","url":"https://endohaus.com/checkout/cart/","invalidateInfo":{"tags":["rewards_purchase_55","rewards_purchase"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:17:21] main.DEBUG: cache_invalidate: {"method":"GET","url":"https://endohaus.com/checkout/cart/","invalidateInfo":{"tags":["rewards_purchase"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:17:21] main.DEBUG: cache_invalidate: {"method":"GET","url":"https://endohaus.com/checkout/cart/","invalidateInfo":{"tags":["rewards_purchase_55","rewards_purchase"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:17:21] main.DEBUG: cache_invalidate: {"method":"GET","url":"https://endohaus.com/checkout/cart/","invalidateInfo":{"tags":["rewards_purchase_55","rewards_purchase"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:18:14] main.DEBUG: cache_invalidate: {"method":"GET","url":"http:/","invalidateInfo":{"tags":["helpdesk_gateway"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:18:14] main.DEBUG: cache_invalidate: {"method":"GET","url":"http:/","invalidateInfo":{"tags":["helpdesk_gateway_1","helpdesk_gateway"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:18:14] main.DEBUG: cache_invalidate: {"method":"GET","url":"http:/","invalidateInfo":{"tags":["helpdesk_gateway_1","helpdesk_gateway"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:18:14] main.DEBUG: cache_invalidate: {"method":"GET","url":"http:/","invalidateInfo":{"tags":["helpdesk_gateway"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:18:14] main.DEBUG: cache_invalidate: {"method":"GET","url":"http:/","invalidateInfo":{"tags":["helpdesk_gateway_2","helpdesk_gateway"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:18:14] main.DEBUG: cache_invalidate: {"method":"GET","url":"http:/","invalidateInfo":{"tags":["helpdesk_gateway_2","helpdesk_gateway"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:18:14] main.DEBUG: cache_invalidate: {"method":"GET","url":"http:/","invalidateInfo":{"tags":["helpdesk_gateway"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:18:14] main.DEBUG: cache_invalidate: {"method":"GET","url":"http:/","invalidateInfo":{"tags":["helpdesk_gateway_3","helpdesk_gateway"],"mode":"matchingAnyTag"},"is_exception":false} [] [2016-05-01 02:18:14] main.DEBUG: cache_invalidate: {"method":"GET","url":"http:/","invalidateInfo":{"tags":["helpdesk_gateway_3","helpdesk_gateway"],"mode":"matchingAnyTag"},"is_exception":false} []

Same thing is with system.log
Anyone has an idea?

I think I'll PR a debug switch for that. Logs get too cluttered.

[viktor-zhuromskyy]

Yes, there should be an interface or option to set logging verbosity level directly in app/etc/env.php

[piotrekkaminski]

@adragus-inviqa that would be very helpful

[atIOCrON]

I'm also interested in this

[jsakars]

I wonder how such a mainline functionality has been missed. After all - M2 is using Monolog by default.

[adragus-inviqa]

Sorry, peeps. Not much time to do this. Consider it "up for grabs".

[andimov]

This issue has been fixed and delivered to mainline.

[shamoon]

DId this ever actually make it into the core? Still having this issue on 2.1.3, dont see where to change it.

[erikhansen]

I'm also interested to hear how to configure a production instance of M2 to not log the cache_invalidate strings to var/log/debug.log

[shamoon]

@okorshenko @andimov Any idea why this never actually made it to the core?

[LucScu]

So, how to decrease log verbosity level to debug.log in production mode?

[orlangur]

@nikonratm @erikhansen @LucScu looking at commits in this issue it seems that dev/debug/debug_logging configuration option is responsible for this in dev mode. However, it looks like the fix is only present in develop branch currently.

As a workaround I believe it would not hurt simply symlink var/log/debug.log to /dev/null: http://serverfault.com/a/779437

[LucScu]

@orlangur Great, i'll see if it is fixed in last release.

[SAN1TAR1UM]

I don't see anything in EE 2.1.7 can we get some more info on where this setting is in the Admin Panel?

[sunilit42]

=> i added that preference , but some how it called first Magento\Framework\Logger\Handler\Debug
then Magento\Developer\Model\Logger\Handler\Debug,

so still magento creating debug.log file.

Any idea?

[simonmaass]

I still have the same debug log entry in 2.2.2:

[2018-01-09 17:01:16] main.DEBUG: cache_invalidate: {"method":"GET","ur...

[scottsb]

@simonmaass and any others: it appears this will be fixed in 2.3.

[erikhansen]

I'm leaving this here incase anyone looks at this issue thread and tries to figure out why the debug.log file is empty on 2.2.x: Stack Exchange - debug.log file is empty in Magento 2.2.x
