Re: [ovirt-users] Info on network interface threshold alert

2017-03-13 Thread Alona Kaplan 
Hi,

The calculation of the tx rate in percentage is -

txDiff = currentCumulativeTx - previousCumulativeTx
timeSlot = currentTime - previousTime

txRate = txDiff / timeSlot

ratePercentage = 100 *  txRate / speed

The message is displayed in case 'ratePercentage' is bigger than 95%.

If you have 'dwh' installed you can see the history.

Alona.

[ovirt-users] Info on network interface threshold alert

2017-03-08 Thread Gianluca Cecchi 
Hello,
this morning I get these two messages regarding bond1 and its active
interface on one host (ovmsrv07):

Host ovmsrv07 has network interface which exceeded the defined threshold
[95%] (bond1: transmit rate[96%], receive rate [0%])

Host ovmsrv07 has network interface which exceeded the defined threshold
[95%] (enp7s4f0: transmit rate[96%], receive rate [0%])

Actually there is no particular network activity during this latest night...
There have been some different resore jobs during past days...
How is determined this message? Is it perhaps cumulative?

On the host there are 3 VMs and only one of them actively using the network.
In its "Network Interfaces subtab I see
Total RX (bytes)
542,696,952,529

Inside VM OS:
$ uptime
 10:26:50 up 14 days,  1:35,  3 users,  load average: 0.00, 0.04, 0.05

$ ifconfig eth0
eth0  Link encap:Ethernet  HWaddr 00:1A:4A:17:01:5B
  inet addr:10.4.4.66  Bcast:10.4.4.255  Mask:255.255.255.0

  TX packets:21110417 errors:0 dropped:0 overruns:0 carrier:0
  collisions:0 txqueuelen:1000
  RX bytes:193066319488 (179.8 GiB)  TX bytes:20983189756 (19.5 GiB)

Almost confirmaed on host where I have these counter indeed, but I think
they are cumulative for the VM, and not an alert in se

ON ovmsrv07:
$ ifconfig bond1
bond1: flags=5187  mtu 9000
ether 00:1c:c4:ab:3a:dd  txqueuelen 1000  (Ethernet)

Could anyone clarify?
