In case of migration or clean re-install you may need to remove FastNetMon Advanced with all configuration files.
Instructions in this article will lead to complete irrecoverable loss of configuration and all data from server.
These instruction will work for Debian or Ubuntu platforms.
Do not continue unless you’re 100% sure that you do not need that data.
You need to remove FastNetMon’s package first:
sudo apt-get remove --purge fastnetmon
Then you will need to remove all MongoDB packages and configuration for them:
sudo apt remove --purge mongodb-database-tools mongodb-mongosh mongodb-org mongodb-org-mongos mongodb-org-server mongodb-org-shell mongodb-org-tools
Next step will lead to complete irrecoverable data loss. Please make full server backup to reduce your disk of data loss.
Remove all configuration files and databases:
sudo rm -rf /etc/fastnetmon/ /var/lib/mongodb/ /etc/apt/sources.list.d/fastnetmon.list /etc/apt/sources.list.d/mongodb-org.list
After that you may start installation again if needed.
