your graph look pretty amazing.
I have trying the option to multiply in the target line by 12, but i was
Target[messages-3]: mailstats * 12
Thanks for your sugestion of multiplying by 60.
Right now I using the option perhour and sampling every 60 minutes.
Will try to sample every 5 minutes and multiply by 300.
I use a custom bash script to output the data from the mailstats
program. It outputs the same counter that the mailtstats program does.
Maybe I can save the previuos counter state and output only the diference
so I get something like the gauge option will do.
This is the current config with samples every 60minutes.
