One thing is currently missed into README.md of the sample project is database. If you have no MySQL installed on the host machine, you can use docker-compose.
My simple docker-compose.yaml looks like:
`
version: '3'

services:
database:

image: mysql:5.7
environment:
  MYSQL_DATABASE: blackfire
  MYSQL_ALLOW_EMPTY_PASSWORD: 'yes'
ports:
  - 3306:3306

`

Hi, When I click on Profile! on the Chrome extension, I only get 10% and then stop. I never have 100% done.
I have blackfire-agent run and probe extension enable (by check php -m).
Am I missing something on installation in 2022?
Thanks

Hey Dang,

Do you get any errors? I'd expect an authorization error or something similar

|

Dang MolloKhan 3 years ago

Yes, when I run by the CLI: blackfire curl https://127.0.0.1:8000 I have this error: Are you authorized to profile this page? No probe response, Blackfire not properly installed or invalid signature for relaying agent.

I installed with the Blackfire v2 , option "as quickly as possible" on linux machine. I have then the file .blackfire.ini with client-id, client-token and a file named agent in /etc/blackfire which contains the server-id and server-token.

Hey Dang,

I found this warning in the Blackfire page

PHP will likely crash when Blackfire is used when one of the following extensions is also enabled: XHProf, Pinba, and Suhosin.

If XDebug is installed, the PHP engine may not behave as expected; consider disabling it when profiling.

If pcov extension is installed, Blackfire will not behave as expected; consider disabling it when profiling.

Is it possible that you have any of those tools installed? If that's not the case, I think you'll have to configure the "probe" to log more info and see if we find a hint of the problem https://blackfire.io/docs/php/configuration
Oh, and this may sound silly, but double-check that you introduced your credentials correctly

Hey hanen

Interesting, have you followed this installation steps? https://blackfire.io/docs/u...
I guess you have wrong DLL file

Cheers!

hanen sadikoff 6 years ago

hi , I tried loding the following file and it works :)))
https://packages.blackfire....

Perfect! Looks like you had wrong library, I'm glad to see that everything is solved!

Cheers!
