I cannot get the RRD file to be created.
I have a script that polls a firewall via SNMP and returns the CPU usage. The test works fine and creates a column named "fwcpu".
bb 127.0.0.1 "status firewall.fwcpu green $now_string \n\ncpu : $cpu"
Try adding an extra "\n" at the end of your output: bb 127.0.0.1 "status firewall.fwcpu green $now_string \n\ncpu : $cpu\n"
That should do the trick
