Netdata package is now available in XCP-ng

stormi

As far as I know, they should be available. I/O metrics aren't at the moment, but RAM should be.

@stormi Could it be that there is any difference between the "netdata-ui" rpm package you provide and the official netdata rpm packages?

netdata-conf-1.23.2-1.el7.noarch
netdata-data-1.23.2-1.el7.noarch
netdata-1.23.2-1.el7.x86_64

Or could it be that it's related to XCP-NG 7.x? Because our cluster is still running 7.x ...

stormi

There definitly is. Ours is built with xen support. You seem to have enabled CentOS and/or EPEL repositories on your host, which is not recommended.

See https://xcp-ng.org/docs/additionalpackages.html

When I try to activate the Netdata plugin I get the error "Netdata is not available on this appliance, please deploy a new one". This is a fresh installation, but I did go to the web site and repeated the XOA deployment... and upgrade, reregister, etc., even though it made no sense to me. The result was the same error.

What am I missing?
Best,
Razvan

Maybe a bug in the appliance. Can you open a support ticket and a tunnel so we can take a look?

LunarstarPony

I've got 2 hosts, Trying to install via XOA One of em works fine but the other one having this Error

Installation error
The installer could not prepare the required dependencies to enable Netdata Cloud functionality

and when I tried to connect by changing the URL this shows up
This netdata does not maintain a database for host: xcp-ng-ksu-backup

olivierlambert

Check if netdata is running in your dom0

LunarstarPony

@olivierlambert

Any idea how?
Or what's the command to check that?

olivierlambert

If it runs, there's a netdata service that should be up

LunarstarPony

@olivierlambert Hmmm How can I check that?

olivierlambert

It should be a systemd service IIRC, so systemctl status netdata

It seems working

olivierlambert

Then check if it's streaming correctly to the target

LunarstarPony

@olivierlambert
BTW Will Changing Hostname on the server break this?
I just change it's hostname recently

olivierlambert

Yes it's probably that.

LunarstarPony

@olivierlambert
Well Anyway to fix it or reinstall it?

olivierlambert

You should take a look in the netdata config on your host and check if it's streaming to the right XOA, check Netdata logs and so on.

LunarstarPony

@olivierlambert Any idea where's the netdata config file location?

stormi

/etc/netdata/streaming.conf IIRC.
