Our client has an old Dynatrace managed installation on it's cluster. They want to get a new trial and try the product again, so we will reinstall everything and start from scratch.
I can see from the documentation that it is pretty straightforward to uninstall cluster nodes, but what happens to OneAgents when we remove managed nodes completely? Do we also need to remove all the agents before proceeding with the uninstallation script, or does the script also handles that part for us?
Solved! Go to Solution.
OneAgents will not be able to communicate to the cluster that was uninstalled. But apps will be instrumented and OneAgent still running on all host.
When you reinstall the cluster, you need to also reinstall OneAgents - so they get new address and auth tokens.
@Radoslaw S., @Piotr S. could we add it to the doc? We could reference the OneAgent installation docs (It's Linux only) because to uninstall OneAgent completely requires you to delete configuration as well.
IMHO it's not needed.
