Bandwidth GUI and Multiple LAN Connections


  • Moderator

    On Fog 0.33 (but this issue also occurred in a separate 0.32 install), if the Fog server has multiple ethernet ports that Linux (Debian 7.5 in this case) has been allowed to team, the Transmit and Receive graphics on the main Fog GUI screen never seem to report bandwidth usage.

    Obviously this is not a dire issue… everything else works golden. Just curious if anyone else has run into this and has any fixes.

    Maybe in the near future I can get it so when you change the storage node to another storage group that updates the graphs appropriately but my knowledge’s wrath like it’s displayed four of the maximum number of clients is always the first one is fine

  • Hi,

    no i have 3 storage group, default, second and third.
    Each group has one storage node, default (fog main 50gb) and a storage node (s) with 2x 1TB Raid /images and /images2.

    If i use (to test) the defaultmember it shows used slot and throughput.
    If i use one of the 1TB nodes it doesn’t show used slot and throughput.

    Every Storagegroup or at least every containing node has its default 10 slot’s, dashboard is showing 30 slots in summary.
    Wait i will post some pictures!

    Regards X23

    It should show the number of slots of the combined amount of nodes within the group you’re working on. I imagine the reason you’re seeing zero slots is because the number of maxclients for the node within the group is set to 0?



  • Hi,

    ok understood ;) i’ve edited my post above, will this also fix the slot usage?
    Will the missing slot usage really cause that more slots can be used or are they just not shown?

    Regards

    There already is a file that does it, but it’s all due to the interface it’s trying to access, doesn’t get sent properly, hence why I want to rewrite the file to work similar to how the freespace.php file works to get the disk space now.



  • Hi,

    just my 50 cent but isn’t there a way to place a php file on running apache on a storage node (S) that can be polled by the main server?
    Do you talk about both problems? Used Slots and througput? I am asking because i will not understand why slot usage should no work without direct netdev access.

    Regards X23


  • Senior Developer

    I know of the issue, but not how to fix the issue.

    I think this is because the GUI needs access to the direct netdev. If the nodes are the ones being connected to, there’s no simple way to get the network bandwidth data of that system. Though I am working to recode that particular page in the near future to correct this, it’s going to be a low priority issue for right now.



  • Hi,

    i have a familar problem, defaultmember will always show used slots and throughput but this does not work for additional storage nodes (S) for me both used slot and throughput is 0, graphs are drawn but left empty.

    I don’t have multiple nic’s, as it works for default node this must be some sort of missconfiguration or bug.

    I am acutally on SVN 2120

    eth0 is the interface set… everywhere I can think to look. eth1 is also linked, but I never specifically set any Fog related services to touch that interface.


  • Senior Developer

    Is the interface set?

    So for example, it defaults to interface eth0, but can be told to look at any interface.

    So if bond0 is your teamed NIC’s, point the interface there.

    I’ve tested it in IE, Firefox, and Chome. They show the chart, just no graph is ever drawn on it regardless of actual throughput.

    what browser?

    I’ve seen the graphs not work in some browsers (unless tom has fixed that)
