[rrd-users] rrd creation - please help!

[Kenny Chan]

I'm new to rrdtool. I need to modify our current rrd creation script 
which created by someone who no longer working here. What I need to do 
is to record number authentications (user logins) per minute. I need to 
create graphs for daily, weekly, monthly and yearly.
Can  someone please verify following script to see if It's done 
correctly or reasonbly?
The time in RRDs::update() function, does it needs to be same as step 
time, '60' in this example?
Is the hearbeat value '300' defined in DS reasonable?

Thanks in advance for the help.
Kenny
