Scylla OSS 5.2.9 fails to start with Dynatrace agent installed

Hi ScyllaDB team,

For instance monitoring we use Dynatrace Oneagent software. This software needs to start before ScyllaDB starts. So we install OneAgent, starte OneAgent service then ScyllaDB.
But Scylla OSS 5.2.9 fails to start and dumps below log. Can someone help resolving this error please.

We have seen problems with Dynatrace agent running alongside Scylla before. As it hooks to processes, it can cause not only Scylla to stall but in worse scenarios it may even cause the process to get hang. The general recommendation is simply not to run 3rd party processes along with Scylla. But if you really really must it, then contact your Dynatrace support team and ask for instructions on how to tell the agent not to hook to the Scylla process and also for the proper way to pin the agent to use specific CPUs, that Scylla is/will not actively (be) using.
