Netdata package is now available in XCP-ng

Thanks for the feedback

I know this topic is quite old but I thought I might add a point here to installing Netdata manually.
Installing Netdata manually
If you want to do it your way, no problem Just run yum install netdata-ui on each host you want to monitor and that's it. You can just go on http://host_address:19999 and enjoy all the metrics.These instructions are correct however at least for me in the xcp-ng 8.0 release there is an active firewall in place. You'll need to open the port 19999 within iptables. The config file for iptables is /etc/sysconfig/iptables. Edit the file to open the port and try to be as restrictive if possible possible filtering by source port. Restart the firewall service:
systemctl restart iptables.service
Access can be further restricted as well within the netdata setup as documented here: https://docs.netdata.cloud/web/server/. You can setup psuedo access-control-lists and even add SSL certs if necessary.
-
The netdata-ui package automatically opens the 19999 port. It didn't work for you? Any error message during installation?

@stormi said in Netdata package is now available in XCP-ng:
netdata-ui
It does but it's too open, so ones can decide to edit this rule and restrict it further
NETDATA all -- anywhere anywhere
-
I'll try to install package again manually once I upgrade to 8.1. Unfortunately for me on 8.0 the firewall port wasn't opened. I'll report once I upgrade.
-
It may fail to open the port if there are local changes to iptables rules.

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
netdatapackage to XCP-ng and configure it to stream towards XOA's netdata. - Or,
yum install netdata-uion XCP-ng will get you a working netdata with default settings and will open port 19999

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
