Re: [Declude.JunkMail] Slightly OT: calculating bandwidth
Oops, the last script below should actually be:
grep rdeliver m:\imail\spool\sys0203.txt | gawk -f IMail-SMTP-RD.txt
rdeliver instead of ldeliver.

Im trying to figure out how much bandwidth my imail
server sends/receives, I know its best to do this on the
router level, but I don't have access to these. Is this
information stored in any log file ?
I know I am starting to sound like a broken record about this, and I not
sure why people are afraid to try them, but the UNIX utilities for Win32
are
available for free download at http://unxutils.sourceforge.net/. With
these
tools you could easily do this by parsing your IMail log files.
Here are three examples:
Incoming (SMTPD) minimum, average, maximum, and total bytes/kb/mb:
(save the follow to a file called IMail-SMTPD.txt)
-
NR == 1 {a=$(NF-0) ; b=$(NF-0)}
$(NF-0) = a {a = $(NF-0)}
$(NF-0) = b {b = $(NF-0)}
{c += $(NF-0) ; d = c/NR}
END {print SMTPD: Min = ab, Avg = d/1024kb, Max =
b/1048576mb, Tot = c/1048576mb}
-
Then execute this script:
egrep SMTPD.*\.SMD m:\imail\spool\sys0203.txt | gawk -f IMail-SMTPD.txt
Which will produce output like:
SMTPD: Min = 263b Avg = 50.8899kb Max = 11.7192mb Tot = 356.627mb
=
Outgoing (SMTP) minimum, average, maximum, and total local delivery:
(save the follow to a file called IMail-SMTP-LD.txt)
-
NR == 1 {e=$(NF-0) ; f=$(NF-0)}
$(NF-0) = e {e = $(NF-0)}
$(NF-0) = f {f = $(NF-0)}
{g += $(NF-0) ; h = g/NR}
END {print SMTP-LD: Min = eb, Avg = h/1024kb, Max =
f/1048576mb, Tot = g/1048576mb}
-
Then execute this script:
grep ldeliver m:\imail\spool\sys0203.txt | gawk -f IMail-SMTP-LD.txt
Which will produce output like:
SMTP-LD: Min = 734b Avg = 50.5353kb Max = 8.5895mb Tot = 266.692mb
=
Outgoing (SMTP) minimum, average, maximum, and total remote delivery:
(save the follow to a file called IMail-SMTP-RD.txt)
-
NR == 1 {i=$(NF-0) ; j=$(NF-0)}
$(NF-0) = i {i = $(NF-0)}
$(NF-0) = j {j = $(NF-0)}
{k += $(NF-0) ; l = k/NR}
END {print SMTP-RD: Min = ib, Avg = l/1024kb, Max =
j/1048576mb, Tot = k/1048576mb}
-
Then execute this script:
grep ldeliver m:\imail\spool\sys0203.txt | gawk -f IMail-SMTP-RD.txt
Which will produce output like:
SMTP-RD: Min = 482b Avg = 49.6214kb Max = 11.7196mb Tot = 134.908mb
Watch for word-wrapping on the last line of each script (each script
should
only be five lines long). Good luck,
Bill

Thank you so much Bill, this is what I was looking for. Ill give it a shot
and let you know.

RE: [Declude.JunkMail] Slightly OT: calculating bandwidth
... Then execute this script: egrep SMTPD.*\.SMD m:\imail\spool\sys0203.txt | gawk -f IMail-SMTPD.txt Which will produce output like: SMTPD: Min = 263b Avg = 50.8899kb Max = 11.7192mb Tot = 356.627mb Ok, great script, but one question: As I can understand this script will read values from the logfile that indicate message sizes. So the min and max values are not minimum and maximum bits per second (for which time range? 5 minutes?) but are the smallest and largest processed messages in this logfile. This has nothing to do with maximum bandwith usage! The average value can also be calculated with delog: Read the total incoming or outgoing bytes at the end of the report and divide them by the factor 10800 This will transform the units from Bytes/day in Bits/second (the common used unit for this type of data) So a total incoming trafic of 1 GB/day will create an average bandwith usage of 92592 Bits/second (~ 92 kBit/s) for the entire day. (note: this is only the incoming value) Based on the data in the SMTP logfile it's not possible to calculate the real peak value or real traffic usage diagrams because even if you calculate every single message from his begin of transfer to the end this will be only an average value for this single message (the transfer rate can go up and down durring the transfer of a singel message). You can try to watch windows perfmon values or enable SNMP on this windows server. Alternatively you can put a SNMP enabled device like HPs Procurve switches between your server and the router and then read out values from there.

This has nothing to do with maximum bandwith usage! Correct, however, from Omar's original post, it seemed like what he was really looking for was actually the amount of data flowing into and out of his server. If he really wanted IMail based bandwidth utilization, then using RRDtool is the way to go. The average value can also be calculated with delog: Read the total incoming or outgoing bytes at the end of the report and divide them by the factor 10800 This will transform the units from Bytes/day in Bits/second (the common used unit for this type of data) Sure, if you want to wait for some number of hours for Delog to parse your log file and then manually do the calculations, fine. However, if you want the results in seconds, then use the scripts I provided.
