Subject: [Courier-imap] How to count distinct users?
Hi,
for our stats, we would like to count the number of distinct users
connected through IMAP/IMAPS/POP/POP3S.
Our settings:
FreeBSD 6.0-RELEASE-p6
courier-imap 4.1.0
courier-authlib 0.58
~ 80k accounts authenticated with LDAP
We've attempted to:
- ps ax | grep couriertls, or
- netstat -an | grep 993 ... <and 143, 110, 995> | grep ESTABLISHED
=> doesn't count distinct users, since one user may open
many connections
- netstat -an | grep 993 ... | count-each-ip-address
=> doesn't count distinct users, since one IP address may
hide many users (multi-user computer or NAT-gateway)
- tail -f /var/log/mail.log | parse-output
=> not real-time, fragile if log format changes, and subject
to interruptions if syslogd fails
Our dream would be to have a record somewhere of active connexions
with the user login, the protocol and the start-time. However, a
"setproctitle()" with the user login would be nice.
Do you have any clue?
Thanks in advance,
Pierre David
This is for Linux - may work for you:
ps -ef | grep -v root | grep "imapd\|pop3d" | awk '{print $1}'| sort |
uniq | wc -l
with ldap authentication, each imad/pop3d process belongs to the same
user, then it doesn't work.
i think process perent for each user is the same, so:
ps -ef | grep -v root | grep "imapd\|pop3d" | awk '{print $3}'| sort |
uniq | wc -l
should work.
i might be wrong though
