If zpa module is not showing in "php -m" command, the php agent will not be collecting data. Kindly ensure if the zpa.ini file is present in the path given by the following command. (If not, kindly copy the /opt/zpa/bin/zpa.ini to the same path)
|php -i|grep "Scan this dir"
And ensure if zpa.so is present in the path given by the following command,
|php -i|grep extension_dir
Also kindly ensure that your webserver is restarted. By the way, do you run apache?
Thanks & Regards,
Developer, APM Insight PHP Agent
