Netdata not showing Virtual Network Interfaces for VMs #379

Open biggen1684 opened 4 years ago

biggen1684 commented 4 years ago

Netdata is currently not showing virtual network interfaces for VMs when looking at the default Netdata dashboard as shown below:

netdata_no_nic

This was noted by vlvkobal during the initial build of Netdata for xcp-ng. He mentions that xentop doesn't report network statistics. I've created a duplicate ticket over at the Netdata Github as I'm not sure who can fix this.

As it stands currently, its not possible to properly monitor network activity on any VMs via Netdata on xcp-ng.

Thanks @biggen1684 for the detailed report. @beshleman will have a look when available.

biggen1684 commented 4 years ago

Thanks @stormi

I also noticed that the virtual drives for the VMs also aren't listed for some reason. Didn't think it was worth starting a new issue over that. I think Netdata just isn't getting everything it needs right now from xcp-ng for some reason.

@stormi The devs over at Netdata closed this ticket I created over there (https://github.com/netdata/netdata/issues/8810). They say they can't do anything about it since its a problem with libxenstat which makes sense.

I think it's been also mentioned on the forum that stats about VDIs are missing too.

Here is the result of an xl top:

Clearly, there's a problem on network.

This old PR for blktap may be related, for disk stats only https://github.com/xapi-project/blktap/pull/170/files

Was there any development on this issue? I am looking for a way to collect the network usage of all VMs and send that to an InfluxDB database but without running something inside each VM, I wanted to collect from the host if possible, or maybe via XO since XO does show me the network usage of each VMs.

olivierlambert commented 1 year ago

It should work via XO (which is using XAPI RRDs).
