Netdata package is now available in XCP-ng
-
Hi,
Would pulling the latest version of netdata into each host break anything?
ie running from the cli: bash <(curl -Ss https://my-netdata.io/kickstart.sh) -
Despite being not supported as any dom0 modification, it would probably not include Xen support.

@MrMike please use our packages
-
Just being curious, your packages, they use a private registry on the xoa server itself?
-
All RPMs are installed from our public repositories, if that's the question.
- Using XOA to install netdata will install the
netdata
package to XCP-ng and configure it to stream towards XOA's netdata. - Or,
yum install netdata-ui
on XCP-ng will get you a working netdata with default settings and will open port 19999
- Using XOA to install netdata will install the
-
I meant about the how netdata centralizes the nodes information on xoa host:
is this how the xoa plugin/packages was configured?

It's using Netdata streaming. Please read Netdata documentation.

@MrMike Hi, The netdata on the hosts is configured to stream towards the Xen Orchestra VM when activated from there.

yea, that's exactly what I was wondering. I'm curious how it was done. I was thinking of doing something similar for my ELK cluster and a few other systems.
-
The Netdata plugin is really great, but would like to be able to stream to cloud.netdata but for that to work we need to have an updated package >=1.20
Is there a package update in the works?

-
Hmm, I did not plan to update netdata before the next release of XCP-ng, because I don't trust their QA enough for that. However I can provide updated packages in the testing repo.
-
Testing would be fine when @r1 modification is done With enough community to test it, we can promote it into main then

After running the command "yum install netdata-ui" on 2 hosts. Only one started working.I can reach the netdata page on the working server at: url:19999. I've rebooted the newer of the 2 servers and no matter what I've tried the netdata page doesn't appear.
If I try the command again I receive an error indicating that the package is already installed and there is nothing to do.
Is there an easy way to fix this or, what's the command to rollback this install?
Thanks to everyone in the community (especially @olivierlambert) for your hard work on this software.

Double check your firewall on the "non working host". Also check if Netdata service is up

Imagine that I don't know what to do. I've tried reviewing the Netdata documentation but it isn't specific to XCP-NG.
I ran the below code and received a response. Does that indicate where the issue could be? Also...what code do you suggest I run to check to see if Netdata is running? Why can't it bind to the host address?

@PC_123 said in Netdata package is now available in XCP-ng:
Address already in use
It means there's already a service listening on this port. Try to stop it and see if it's still there on this port.
