Nagios as Cron

[Ben Clewett]

Personally I would always use the tool designed for that task.  Cron is 
designed to run precesses very reliably at specific time.  Nagios is 
designed to collect data from plugins....  Eg, Nagios might timeout your 
plugin whilst still in the process of the ftp.

If you are uploading an hourly data file, would it not be better to 
write a plugin to check that the data file is there and less than one 
hour old?
