Meaning of network data in system bottlenecks screen

Hi,

 

I am running Vertica 7.1.2.2 and 7.1.2.4 MC.

The "system bottlenecks" tab of the activity screen in the MC says that network Tx/Rx goes even higher than 100%.

 

At the same time, my network monitoring tool (collectl) says I am using 160 MB/sec, on a 10GB network.

If I try to add on this network a file transfer, overal traiic can go up to 300 MB/sec.

 

So why Vertica MC is telling me my network is used at more than 100% ??

Is the MC assuming my network is 1GB, instead of 10 GB ...?

 

Thanks for helping

    Hi Luc_Lecocq,

     

    Looking at the query used, it does look like the MC assumes 100% network utilization as 1 gigabit per sec.

    Thanks Chris,

     

    Any chance this is going to be fixed ?

    There is always a chance :)

    The team and I will evaluate the best way to present this information given variable network bandwidths. 

     

    Regards,

    Chris
