Common Errors

vault_newrelic_license is not defined

Encrypt your New Relic license key in group_vars/<environment>/vault.yml. See role variables.

New Relic merges multiple environments into single application

Solution: Define different appname for different environments.

Error after upgrading PHP version

New Relic would fail and causes provision end up in errors when upgrading PHP major or minor releases (e.g: from 7.4 to 8.0, from 8.0 to 8.1).

non-zero return code
PHP Warning:  PHP Startup: Unable to load dynamic library 'newrelic.so'
(tried: /usr/lib/php/20180731/newrelic.so (/usr/lib/php/20180731/newrelic.so:
cannot open shared object file: No such file or directory),
/usr/lib/php/20180731/newrelic.so.so (/usr/lib/php/20180731/newrelic.so.so:
cannot open shared object file: No such file or directory)) in Unknown on

After each PHP major or minor release upgrade (i.e: when you see the above error):

# For multi-server setups, perform the following steps on each server.
ssh admin@123.456.789
sudo newrelic-install install
sudo reboot

# Wait for the server(s) to reboot and then re-provision
# For multi-server setups, you only need to re-provision once only
trellis provision production

Limitations

• Only one New Relic APM application per server by default.

Extends the fastcgi_basic block to include fastcgi_param PHP_VALUE "newrelic.appname={{ item.key }} ({{ env }})"; right after the line include fastcgi_params; to work around this limitation.

Pull requests are welcomed.
