Netdata package is now available in XCP-ng

@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)

LunarstarPony

@stormi Oh No, have any idea what might be the problem?

stormi

No, I don't know where the problem resides exactly.
