Re: [Moosefs-users] mfs mount generates high trafic from chunks

[Eduard I. <edu...@di...>]

Hi.

This is the traffic incoming on port 9422 in the mount server:
 --------------------------------------------------------
 |  Rate  |              Average for                    |
 --------------------------------------------------------
 |########|    3 sec     |    15 sec     |    30 sec    |
 --------------------------------------------------------
 |  bits  |    154.2M    |     142.4M    |     145.7M   |
 |  pkts  |     13.1K    |      12.1K    |      12.3K   |
 --------------------------------------------------------


This is the outgoing port 80 from the same server:
 --------------------------------------------------------
 |  Rate  |              Average for                    |
 --------------------------------------------------------
 |########|    3 sec     |    15 sec     |    30 sec    |
 --------------------------------------------------------
 |  bits  |      1.6M    |       1.2M    |       1.2M   |
 |  pkts  |      171     |       129     |       127    |
 --------------------------------------------------------


I also attached a screenshot. If it's not what you needed, please let me 
know.

Thanks,
