While metrics are emitted by every php version, we need to check/fix the following things:
- mtail regex doesn't match the php 7.4 handler
- flamegraphs from xhgui - do we split on php version already? we probably need to
- logstash dashboards - they should already include a filter based on the php version, but better check
Export and collect phpfpm metrics with prometheus-phpfpm-exporter for all versions of php.
- prometheus needs to collect php7.4 metrics
- grafana dashboards should at the very least allow selecting which version of php to collect data for
