RX/TX values in API are computed from RX/TX percentages and max bandwidth of the interface (provided by speed attribute), so if speed is zero, the also RX/TX are zeros. Could you please take a look at the value of speed attribute? If it's non-zero could you please check RX/TX values in webadmin if they are the same as in API?
in my setup i have speed 0, and rx/tx values are "<1"
(In reply to Marian Jankular from comment #2) > in my setup i have speed 0, and rx/tx values are "<1" Can you try and run some traffic over?
I did tried on our 4.1 environment which has load - 20 vms per node in web ui i see speed 1000, rx rate is 10, txrate is <1 however when using api i am still getting no value for current "name" : "data.current.rx", "description" : "Receive data rate", "href" : "/ovirt-engine/api/hosts/f1e96245-7ca3-4729-8abf-980501380a2b/nics/a442b3d7-7d3e-456b-a9cb-900d22171464/statistics/ecd0559f-e88f-3330-94b4-1f091b0ffdf7", "id" : "ecd0559f-e88f-3330-94b4-1f091b0ffdf7" }, { "kind" : "gauge", "type" : "decimal", "unit" : "bytes_per_second", "values" : { "value" : [ { "datum" : 0 } ] }, "host_nic" : { "href" : "/ovirt-engine/api/hosts/f1e96245-7ca3-4729-8abf-980501380a2b/nics/a442b3d7-7d3e-456b-a9cb-900d22171464", "id" : "a442b3d7-7d3e-456b-a9cb-900d22171464" }, "name" : "data.current.tx", "description" : "Transmit data rate", "href" : "/ovirt-engine/api/hosts/f1e96245-7ca3-4729-8abf-980501380a2b/nics/a442b3d7-7d3e-456b-a9cb-900d22171464/statistics/2c6fe105-4913-3f90-9425-07ddfeca5417", "id" : "2c6fe105-4913-3f90-9425-07ddfeca5417" }, { "kind" : "counter", "type" : "integer", "unit" : "bytes", "values" : { "value" : [ { "datum" : 199652833504 } ]
I'm not able to reproduce on RHVM 4.1.2, it works as expected (checked on several hosts): 1. When rx/tx rate in webadmin is <1, then it's shown as 0 in restapi 2. When speed is non-zero and rx/tx rate in webadmin are different than <1, non-zero values are shown in restapi @Dan, is there any known issue around this area?
Moving to network team.
We are planning to release a metrics store next month that will allow you to collect raw value more accurately. The customer will probably want to move to this for monitoring.
If we change the value type then the DWH will need to be changed as well.

I remember sradco complaining about something similar in the past. Do you recall a bz#?
Verified on - 4.2.0-0.0.master.20170901193740.git7900511.el7.centos
Dan - can we push to 4.1.z? A CFME bug depends on that one.
