In our document we have support till Nginx Plus R30, couldn't find R31 as this would be the latest version.
You can try what I wrote below or wait new version. (recommend if deadlines do not burn)
If there is debug symbols(debug info) for this version from NGINX, you can try to install it
How it is look like for normal nginx:
prerequisites:
nginx -V command output contains --with-debug
export DT_NGINX_FORCE_UNKNOWN_VERSION_INSTRUMENTATION=1
export DT_NGINX_FORCE_RUNTIME_INSTRUMENTATION=on
you can check with gdb - are there any debug symbols for your binary:
gdb /usr/sbin/nginx
Expected output:
Reading symbols from /usr/sbin/nginx...Reading symbols from /usr/lib/debug/usr/sbin/nginx.debug...done.
You can check the logs to clarify what is going on :
tail -f /var/log/dynatrace/oneagent/nginx/*
expected output:
==> /var/log/*_NGINX-WITH-DEBUG-FINAL_startup_59930.0.log <==

a much easier and recommended way to wait for an offset to be added for this version, then the instrumentation will happen automatically. 😉
With love and patience, nothing is impossible (c)
