NeophyteThanks for doing your homework. That helps.
It sounds like perhaps this might be more of an event than data, leading to look at an EventSource. You could setup a scripted EventSource that can log into the device via SSH, execute whatever you are thinking of running through cron, and grab the output. If the output contains number, you'd build a datasource to track those datapoints. If the log contains an indication of failure, you would use an EventSource. The EventSource would then trigger an alert for each offending line in the output.
