Oneagent install coredump

Hi.

Our customer has installed Oneagent. After installing, I noticed that the system files were modified and coredump was enabled. In what directory is coredump output?

When Oneagenet is installed, "/ proc / sys / kernel / core_pattern" and "/etc/sysctl.conf" are modified. Do I need to restart the OS?

From documentation:

"One last thing: to monitor your processes, you need to restart them. At any time, you can check which processes aren't monitored and need to be restarted. Just select Deployment status from the navigation menu, click the All hosts or Recently connected hosts tab, and expand the host you are interested in"

Hi Toshimasa,

The core dumps should be stored in /opt/dynatrace/oneagent/agent/rdp by default.
