jonathannz

The following method does not work for m:

Run wo stack remove --netdata
Then run wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-kickstart.sh --uninstall

sudo wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-kickstart.sh --uninstall

I was just about to go and submit an official bug report. but am happy to see you have already done that alexlii

• WordOps/WordOps#690

I hope this gets resolved soon as I remember having issues uninstalling this for many versions now

alexlii1971 Have you rebooted your server after removing Netdata?

portofacil I just did a reboot and netdata is still showing up as a running/active service

This script is part of a tool I use on non-WO servers. I stripped the parts that don't relate to removing Netdata. Perhaps it can help you.

portofacil I could just copy/paste these commands, right? instead of uploading a script and running it?

The code I provided is not a full script. I only meant to give you a solid starting point.

portofacil oof, I appreciate the effort, truly
but things like this (features offered within the official documentation of WordOps) should actually work

Endda WordOps is open source, and so is its documentation. Perhaps this is an excellent opportunity to contribute to the project (reviewing documentation) without dealing with code directly.

I wish there was an update on this. Removing Netdata doesn't work with the Wordops stack remove command. I even tried to remove the entire admin stack, and that didn't work.
