PHP 8.1 FPM: Missing curl tracking

[adri]

Description

After deploying the New Relic agent v9.19.0 with PHP 8.1 we noticed that the curl integration seems to not track durations and throughput anymore when running under FPM. It works still when in the context of PHP CLI (worker). This worked under PHP 8.1 using New Relic Agent version v9.19.0.

Steps to Reproduce

1. Upgrade to v9.19.0 using PHP 8.0 ✅ curl tracked correctly
2. Upgrade to v9.19.0 using PHP 8.1 ❌ curl not tracked correctly.

Expected Behavior

Curl response duration tracking should stay the same as under PHP 8.1.

Relevant Logs / Console output

However, throughput didn't change:

Your Environment

• Offical php:8.1.3-fpm Docker image with Linux 5.4.172-90.336.amzn2.x86_64 x86_64 GNU/Linux

@adri Thanks for bringing this to our attention.
We'll be investigating it on our side and will reach out if we need any clarifications/additional info from you.

@adri Which framework were you using to send/handle your curl traffic.

[zsistla]

Hi @adri ,
If you could provide a snippet of the code that makes the curl call and also the framework being used for the website, it'll help us reproduce/debug this.
:) Thanks!

@zsistla Good point! I assumed that we use a released version of Guzzle (which uses afaik curl_multi_exec). However, we seem to use a version that fixes an PHP 8.1 deprecation that is not merged and released yet.

• Pass int to &$still_running of curl_multi_exec guzzle/guzzle#2991

Could this be related?

[adri]

I guess this issue can be closed and only becomes relevant when this PR is actually merged.

@aldri, oh interesting! Thanks for the PR link and the update on this.

We use Guzzle 7.4.3 and we updated to PHP 8.1 , now after latest release it seems NR no longer accurately measures external calls

We recently upgraded to PHP 8.1 from 7.4 and all of our external calls are not being tracked. We are using Laravel 9.x which uses Guzzle as well.
