Sorry Jeff, I should have been clearer. I need to reference a router I'm
trying to monitor via its IP address instead of hostname because it doesn't
have a hostname assigned and it would be a bit of a pain to get this done
since I don't have direct access to it. Even if I did have a hostname
assigned, I'm not sure about the nameserver setup and hence whether name
resolution will work correctly.
You mentioned in your beginner's guide to cricket that using an IP address
is possible, but in any of the subsequent documents there is no
explanation. I followed all of the instructions in the beginner's guide
(you didn't have defaults for a Cisco 4500 so I used the 2500 as you
suggested). Then...
Stephen Carville posted his method
(http://www.sugarat.net/hypermail/cricket/0075.html) for a switch, which I
attempted to adapt for my router (in other words, instead of modifying the
switches file he mentions, I modified the /routers/Targets file. When I try
to recompile the config, I get the following errors:
[utsav@redhat utsav]$ ~/cricket/compile

If I then try to run the collector script, the following errors occur:

Here's how I've set up the relevant config files:
~/cricket-config/Defaults:
#
# Top Level Defaults
#
Target --default--
dataDir =
%auto-base%/../cricket-data/%auto-target-path%
rrd-datafile = %dataDir%/%auto-target-name%.rrd
rrd-poll-interval = 300
snmp-host = %auto-target-name%
snmp-community = public
snmp-port = 161
snmp =
%snmp-community%@%snmp-host%:%snmp-port%
directory-desc = "CIS4500 at 157.191.175.11"
<etc.>
~/cricket-config/routers/Defaults (I added the following lines in the
appropriate places)
datasource Traffic-In ds-source
=snmp://public@%switch%/ifInOctets.%port%
datasource Traffic-Out ds-source
=snmp://public@%switch%/ifOutOctets.%port%
targetType port-traffic
ds = "Traffic-In, Traffic-Out"
~/cricket-config/routers/targets
target "McKinsey-RMU"
target-type = port-traffic
short-Desc = "CIS4500"
port = 10
~/cricket-config/router-interfaces/interfaces
target --default--
#router = bsn-router
router = 157.191.175.11
Any help would be appreciated.
Cheers,
Utsav

Uh, I don't understand your question. Cricket sends messages via SNMP,
which travels as UDP packets over IP. So in that sense, it uses
IP. It can measure traffic across interfaces, but the measurement is
independent of the kind of traffic. If you have 5 mb/s of neware
traffic and 2 mb/s of IP traffic, Cricket will measure that at 7 mb/s.
