Hourly Mail Statistics

WARNING: These pages are totally bogus due to the passage of time and the shifting of the continents that has occurred since they were developed.
This page shows hourly statistics related to our mail servers at the University of Washington over the last week.

There are also weekly and daily statistics available.

The Active Users chart shows the number of unique UIDs that appeared to be active during the indicated hour on each computer in the cluster.

The Messages Received chart shows the count of incoming email messages for all users on the indicated cluster.

The Messages Sent chart shows the count of outgoing messages through the jason servers categorized by the source client computers.

The local IMAP sessions are preauthenticated connections coming in from the native cluster. For example when a homer user runs pine which connects to a mailer system.

The remote IMAP sessions are ones coming in from desktop clients or other sessions that are not preauthenticated. There can be spikes caused by one or more users setting their clients to query for new mail every few seconds.

The POP sessions count the total number of times that pop clients query for new mail. If one or more users set their clients up for frequent queries you'll see inflated counts.
