<![CDATA[Nos stats problem (but not the know one I guess)]]>I have upgraded from 8.2.1 to 8.3. No I cant see any stats anymore. But I get a lot of these messages:

  "properties": {
    "method": "vm.stats",
    "params": {

    "message": "connect ECONNREFUSED 127.0.0.1:443",
    "name": "Error",
    "stack": "Error: connect ECONNREFUSED 127.0.0.1:443\n    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16)\n    at TCPConnectWrap.callbackTrampoline (node:internal/async_hooks:128:17)"
  }
}

To me it looks like XOA tries to load the data from 127.0.0.1.
I have another pool connected to that XOA. Also 8.3. No issues. Therefore I assume it is not my XOA that causes that problem. I also update to the latest version via git pull. No change.

Anyone and idea why this is?

are the backup job running normally (if any ) ?
can you disable temporary the backup network ? the rrd stats should be visible immediately afte if this is the root cause

I get that. But the XOA is part of that network as it needs to make the backups. I can also ping the the IPs. I need to go to the datacenter to do more checks. Don't want to do them by remote as the severs are operational currently. Will keep you updated.

That was set. We want to run all backups in a dedicated network (VLAN, 10 Gbit, et,c). That network is completely separated.

Does that mean if I use a backup network, I wont get any stats?
Is there any documentation available on that that I can read?

the rrd go through this

grep "127.0.0.1" state.db brings nothing no result. C

Also hostname ( RO): is set correct. I can find some localhost entries. But for license server, etc. C

Any idea on how to check and change that? Management interfaces seems to be OK on the hosts. I can access and manage all servers. It seems it is just the stats that are not working. C

No, that is not the case. All servers are in the same rack. Connected to the same switch. Same network (VLAN, IP Range).

XOA runs on the master server. No stats for that server. But stats for another server are ok (just one), all the others are not working.

connect ECONNREFUSED 127.0.0.1:443

That's the issue. XO needs to have access to all hosts management IPs, not just the master. I assume you made a tunnel or something specific to make XO connecting to the master. It's not related to 8.2 or 8.3, it's an architecture thing on pools since XCP exists 🙂

For one host, I can see stats. But just for that one host only. Not sure if that helps to point to the right directrion.
