[mrtg] mrtg-ping-probe question

[Bill Whitacre]

I am trying to use mrtg-ping-probe to watch error rates on a T1.

With this cfg file:

WorkDir: /Library/WebServer/Documents/mrtg
Refresh: 600

# T1 ALX ping

Title[t1_alx.ping]: Ping to T1 ALX

LegendI[t1_alx.loss]:  % loss:

and this crontab line:

Library/WebServer/Documents/mrtg/cfg/ping-loss-207.188.192.97.cfg -- 
logging /var/log/mrtg.log

I get the following mrtg errors:

When I run the individual 'target' mrtg-ping-probe commands I get the  
following:

[ibb-80:local/var/log] bw% mrtg-ping-probe 207.188.192.97
15
11

and

[ibb-80:local/var/log] bw% mrtg-ping-probe -t 42 -p loss/loss  
207.188.192.97
0
0

Anyone see anything glaringly wrong?

Thanks.
