Oneagent is uninstalled after rebooting host

atim — Fri, 30 Nov 2018 09:25:18 GMT

I recently add our host to be monitored with dynatrace. After I deploy agent to my host, it said that I should restart the processes in order to be fully visibility monitored. Then I reboot the host, after that the host is not monitored. It is said that "Host is not monitored. OneAgent uninstalled 1 hour 51 minutes ago."

How could this happen?

Hi,

Did you install the agent on root privileges?

Best,

Radek

What is the operating system? Windows, Linux, ...?

Do you have the right communication ports open?

Is there no mechanism for undoing changes on the system after restarting the application?

Could you share agent log?

If oneagent files and systemd unity (or SysV init script) are not there after reboot then your host does some reverting mechanisms such as reverting filesystem changes on reboot to a snapshot.

At 99% there is a mechanism for undoing changes on the machine, as I wrote earlier.
