    Trouble with bandwidth monitoring

    I'm using Zabbix 1.1.4, hoping to replace Big Brother and IPMonitor. I've been trying to create some graphs to track bandwidth, but with poor results. The host I'm currently trying to track is a Solaris 10x86 server, with an agent compiled for that platform.

    Here's what I've done to set up the graph:

    1. Created an Item for the interface with the following parameters:

    net.if.in[e1000g0]
    numeric(float)
    Delta (speed per second)

    2. Associated this item with a graph, and set the graph to all.
    3. Tested it by transferring a 4GB file via scp to the host. The host sending the file shows the transfer occurring at roughly 10MB/sec.

    What I see doesn't make any sense to me. The host is on a gigabit connection, yet I don't see any entry on the graph reflecting any bandwidth usage. If I change the Store Value to As Is (instead of Delta), I get a graph that shows a peak of 25000000000. From the docs I had believed that the default for mode was bytes, but this is clearly inaccurate. I thought it might be bits instead, but that would be over 3GB/sec.

    I'm totally confused about how to set up bandwidth monitoring on an interface now... Any help?

    It looks like a bug either on agent or server side. It would be quite difficult to reproduce, hmm...
