Ok I have cricket working now but I am running into an issues that is
somewhat annoying and I am not sure which to investigate more closely.
Apparently when collector runs sometimes it seems to be unable to grab SNMP
data from my Cisco router. I don't know if this is caused because of:
A. SNMP having a low priority on the Cisco and collector timing out too
soon?
B. My Cisco's CPU is too busy?
C. A bug in the version of IOS I am running? (11.3.9T)
D. Something wrong with DNS resolution?
To see an example of what this is doing to the grtaphs take a look here:

Below are the error messages I get from Cricket's cron job

I am a bit confused about these error messages because some of the things it
complains about don't make sense. For eaxmple in this email it mentions my
portmaster stuff, but that script has been working fine. It just seems like
sometimes its unable to get an instance mapping from my Cisco? Anyone got
any ideas what I am dealing with here? Thanks in advance!
