Enable TCP Fast Open on Linux to send data in the initial SYN, then verify it with curl and tcpdump before rolling it out.
After a PHP deploy, some users still see old code. The cause is often OPcache isolation across PHP-FPM workers, not a failed deployment.
Guide to selecting the right Dynatrace OneAgent mode on Kubernetes: full‑stack DaemonSet, application‑only injection, or infrastructure‑only, with a comparison table, trade‑offs, and a step‑by‑step full‑stack deployment example.
