Dynatrace supports on nginx-plus-r31 and MinIO VERSION 2022-11-11T03:44:20Z

Ankit — Thu, 21 Mar 2024 10:37:21 GMT

We have a premium customer, few of their applications are running on technologies as follow:

Technology	DT Support	Remark
nginx-plus-r31	Unsupported	Unable to find in technology support document link as r31 is the latest version and DT has support till r30
MinIO VERSION 2022-11-11T03:44:20Z	Unsupported	Unable to find in technology support document link

We could not find the above technologies under Dynatrace supported technology. We are not sure if we can monitor these technologies using Dynatrace or not. Can you please help us or guide if we missed anything?
By when can we expect these technologies to come under DT support?

In our document we have support till Nginx Plus R30, couldn't find R31 as this would be the latest version.

MinIO is a GO based server. Please check Go known limitations

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.

https://docs.dynatrace.com/docs/setup-and-configuration/technology-support/application-software/nginx/manual-runtime-instrumentation

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 <== info [native] Found build id in /opt/nginx-debug3/sbin/nginx: 31aa001c43abdaff0fa0ac33d5346c507ec6e0ce info [native] No debug link present in /opt/nginx-debug3/sbin/nginx info [native] No alternative debug link present in /opt/nginx-debug3/sbin/nginx info [native] Trying on-the-fly instrumentation with debug symbols from file(s): /opt/nginx-debug3/sbin/nginx info [native] [on-the-fly] Successful info [native] Starting Nginx agent for binary with MD5 78cd4f397d10503ef2edb55ab2735a33 info [native] Caching offsets to file: /var/lib/dynatrace/oneagent/agent/runtime/0x9959e6090b1d1a7c_nginx_0/nginx-offsets-cache_78cd4f397d10503ef2edb55ab2735a33.json info [native] Detected static modules: * ngx_stream_upstream_zone_module (0x7293e0) ngx_stream_write_filter_module (0x7280e0) info [native] Registering agent via core module hook (default; custom array registration viable as well) info [native] Nginx successfully instrumented

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)
