This is a cool idea! I might suggest that the implementation be generic enough to be able handle other types of graphs as well (even those not invented yet) and yet support Taylor's request.

Perhaps a new report type that requests graphs of a certain type for all hosts (or pages) (with an option to restrict the display to a pattern matched list of hosts for sites with large numbers of hosts).

Kind of like an mrtg style view. That way if we see bandwidth spike on our switch we can pull up this page and get a quick view of which hosts are talking a lot?

Thanks, Taylor

Does the metrics report in hobbit satisfy this?

Select all the hosts in the left column and then select the test you want to compare across all hosts in the right?

Tricky, because network interface names vary from one host to another.

What you can do is to create a multi-graph definition in hobbitgraph.cfg that picks out the exact NIC graph you want. Copy the existing "ifstat" definition, and make a new "eth0-multi" graph where the FNPATTERN refers only to the interface graph you want - i.e. instead of the "ifstat.(.+).rrd" pattern you refer to the exact "ifstat.INTERFACE.rrd" file matching the name of your NIC. E.g. for "eth0":

[eth0-multi] FNPATTERN ifstat.eth0.rrd TITLE Network Traffic YAXIS Bits/second DEF:inbytes at RRDIDX@=@RRDFN@:bytesReceived:AVERAGE CDEF:in at RRDIDX@=inbytes at RRDIDX@,8,* DEF:outbytes at RRDIDX@=@RRDFN@:bytesSent:AVERAGE CDEF:out at RRDIDX@=outbytes at RRDIDX@,8,* LINE2:in at RRDIDX@#@COLOR@:@RRDPARAM@ inbound GPRINT:in at RRDIDX@:LAST: \: %10.1lf (cur) GPRINT:in at RRDIDX@:MAX: \: %10.1lf (max) GPRINT:in at RRDIDX@:MIN: \: %10.1lf (min) GPRINT:in at RRDIDX@:AVERAGE: \: %10.1lf (avg)\n LINE2:out at RRDIDX@#@COLOR@:@RRDPARAM@ outbound GPRINT:out at RRDIDX@:LAST: \: %10.1lf (cur) GPRINT:out at RRDIDX@:MAX: \: %10.1lf (max) GPRINT:out at RRDIDX@:MIN: \: %10.1lf (min) GPRINT:out at RRDIDX@:AVERAGE: \: %10.1lf (avg)\n

Then you can create a new metric on the "Metrics Report" page by adding a new "<option>" ... in the ~hobbit/server/web/hostgraphs_form : Find the "<SELECT" tag and add an option for the "eth0" graph:

<SELECT NAME=testname MULTIPLE SIZE=15>
<option value="ALL" SELECTED>ALL</option>
... other current options ...
<option value="eth0">Network I/O eth0</option>

Note that in hobbitgraph.cfg the name is "eth0-multi", but in the hostgraphs_form it is just "eth0". The "-multi" is added automatically.

You should then be able to view the eth0 I/O from the Metrics report page.
