[rrd-users] Re: Message Monitoring

[PAUL WILLIAMSON]

We do this today.  Is the host system *nix or windows?  For almost 
the same reason!  

Where will RRDTool be running?  Locally or remotely?

I'm in a position where I need to monitor the number of messages being

submitted into certain folders in a collection of IMAP mailboxes. 
Basically, we're beginning to do efficiency testing on some of our spam

solutions and we're pulling one set of data from spamtraps in the form

of quantity of messages in specific folders, namely the inbox and spam

folder.
I would like to use RRDTool to represent this information graphical, 
however, I have never used it before. After reading the brief tutorials

and some of the manpages I am still unsure how to accomplish what I am

looking for. I would like to update the rrd with the number of messages

received and the number of messages flagged as spam. If possible, I 
would like every instance of the pull script per mailbox to update the

rrd and avoid having to aggregate the numbers for ever periodic pull of

all the mailboxes. The latter I find difficult to do as there would be

a flurry of updates every set interval with nothing in between where it

appears RRDTool was built around the assumption of a consistent 
individual update every set interval. Ignoring that requirement, I 
believe the necessary Data Source options would be:

rrdtool create target.rrd --start <start time> --step 3600\
DS:inbox:ABSOLUTE:7200:U:U\ I'm not sure exactly why I chose 7200, 
except that the tutorials appeared to suggest twice the step
DS:spam:ABSOLUTE:7200:U:U\

The main source of my confusion is deciding on the appropriate archive

configuration line as none of the consolidation functions seem 
appropriate. I would like to consolidate these based on sum so that I 
can display, graphically, an accurate measure of the amount of mail and

spam we are receiving into these accounts. I'm sure this all derives 
from my misunderstanding of how the rrd integrates with displaying 
data, but any pointers or suggested reading are appreciated.
