Tricky, because network interface names vary from one host to another.<BR>
<BR>
What you can do is to create a multi-graph definition in<BR>
hobbitgraph.cfg that picks out the exact NIC graph you want.<BR>
Copy the existing "ifstat" definition, and make a new "eth0-multi"<BR>
graph where the FNPATTERN refers only to the interface graph<BR>
you want - i.e. instead of the "ifstat.(.+).rrd" pattern you<BR>
refer to the exact "ifstat.INTERFACE.rrd" file matching the name<BR>
of your NIC. E.g. for "eth0":<BR>
<BR>
[eth0-multi]<BR>
FNPATTERN ifstat.eth0.rrd<BR>
TITLE Network Traffic<BR>
YAXIS Bits/second<BR>
DEF:inbytes@RRDIDX@=@RRDFN@:bytesReceived:AVERAGE<BR>
CDEF:in@RRDIDX@=inbytes@RRDIDX@,8,*<BR>
DEF:outbytes@RRDIDX@=@RRDFN@:bytesSent:AVERAGE<BR>
CDEF:out@RRDIDX@=outbytes@RRDIDX@,8,*<BR>
LINE2:in@RRDIDX@#@COLOR@:@RRDPARAM@ inbound<BR>
GPRINT:in@RRDIDX@:LAST: \: %10.1lf (cur)<BR>
GPRINT:in@RRDIDX@:MAX: \: %10.1lf (max)<BR>
GPRINT:in@RRDIDX@:MIN: \: %10.1lf (min)<BR>
GPRINT:in@RRDIDX@:AVERAGE: \: %10.1lf (avg)\n<BR>
LINE2:out@RRDIDX@#@COLOR@:@RRDPARAM@ outbound<BR>
GPRINT:out@RRDIDX@:LAST: \: %10.1lf (cur)<BR>
GPRINT:out@RRDIDX@:MAX: \: %10.1lf (max)<BR>
GPRINT:out@RRDIDX@:MIN: \: %10.1lf (min)<BR>
GPRINT:out@RRDIDX@:AVERAGE: \: %10.1lf (avg)\n<BR>
<BR>
Then you can create a new metric on the "Metrics Report" page by adding<BR>
a new "<option>" ... in the ~hobbit/server/web/hostgraphs_form : Find<BR>
the "<SELECT" tag and add an option for the "eth0" graph:<BR>
<BR>
<SELECT NAME=testname MULTIPLE SIZE=15><BR>
<option value="ALL" SELECTED>ALL</option><BR>
... other current options ...<BR>
<option value="eth0">Network I/O eth0</option><BR>
<BR>
Note that in hobbitgraph.cfg the name is "eth0-multi", but in the<BR>
hostgraphs_form it is just "eth0". The "-multi" is added automatically.<BR>
<BR>
You should then be able to view the eth0 I/O from the Metrics report<BR>
page.<BR>
