Netdata package is now available in XCP-ng

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

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.

LunarstarPony

@stormi

# do not edit, managed by XCP-ng

[stream]
    # Enable this on slaves, to have them send metrics.
    enabled = yes
    destination = tcp:*********.****.****:19999
    api key = 0b607150-79c6-11eb-9575-c210359af93e
    timeout seconds = 60
    default port = 19999
    send charts matching = *
    buffer size bytes = 1048576
    reconnect delay seconds = 5
    initial clock resync iterations = 60

I found these in stream.conf

olivierlambert

Is the destination matches XO IP address?

LunarstarPony

@olivierlambert
Yup It does match XOA's IP Address

olivierlambert

So check netdata logs in /var/log to see if there's any error.

I see this, which looks good at first sight:

(caution: your log contains the IP address you masked earlier)
