Connection logs

MQIPT provides a connection log facility that contains lists of all successful and unsuccessful connection attempts. It is controlled by using the ConnectionLog and MaxLogFileSize properties. See Global properties for more information.

Each time MQIPT is started, a new connection log is created. For identification, the filename includes the current time stamp, for example:

mqiptYYYYMMDDHHmmSS.log

where

• YYYY is the year
• MM is the month
• DD is the day
• HH is the hours
• mm is the minutes
• SS is the seconds

When a connection log reaches the maximum size as determined by the MaxLogFileSize property, a backup file, mqipt001.log, is created. A maximum of two backup files are maintained (mqipt001.log and mqipt002.log).

An entry in the connection log represents each part of a connection request. A connection request that is received by MQIPT and the resulting new connection that MQIPT makes to the destination address appears as two log entries, and subsequently two further entries when each connection is ended.

Here is the connection log for a successful connection request:

Wed May 15 13:13:51 BST 2013 conn accept 127.0.0.1(3842) 127.0.0.1(5000) OK 5000-0
Wed May 15 13:13:51 BST 2013 conn conn   127.0.0.1(3843) localhost(3500) OK 5000-0
Wed May 15 13:13:52 BST 2013 conn close  127.0.0.1(3842) 127.0.0.1(5000) OK 5000-0
Wed May 15 13:13:52 BST 2013 conn close  127.0.0.1(3843) localhost(3500) OK 5000-0

Here is a connection log for a failed connection request:

Wed May 15 14:56:40 BST 2013 conn accept 127.0.0.1(4138) 127.0.0.1(7000) OK    7000-0
