**Kibana version** : 7.12.1

**Elasticsearch version** : 7.12.1

**APM Server version** : 7.12.1

**APM Agent language and version** : php agent 1.01. Php 7.3.27

**Browser version** : Edge 90.0.818.56

**Original install method (e.g. download page, yum, deb, from source, etc.) and version**: deb from github

**Fresh install or upgraded from other version?** Fresh

**Is there anything special in your setup?** Deployed by eck to k8s cluster, apm server behind nginx. Instrumented application is running in mod\_php in apache.

**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**:  
I was expecting there to be automatic spans created for "significant" function calls but this doesn't seem to be the case. I am getting spans created for curl so spans themselves are working. I'm also not seeing spans for db queries but this is using [PHP: PostgreSQL - Manual](https://www.php.net/manual/en/book.pgsql.php) which is not supported yet.  
Transactions are created as expected. Just no spans for most of them (unless curl does something).

The docs are dance around this a bit, am I expecting too much at this stage?  
FWIW I am instrumenting moodle we are currently using new-relic for this information.
