Monitoring Page


The Monitor Page is broken into two parts. The upper part is displays message's that are received from the network. The bottom part shows messages that are transmitted to the network, either by traffic loading activity, custom message sending, or message gateway. The divider is movable to allow you to adjust which screen should get more space.

A typical monitored packet might look like this:

11:Stn11:172.25.66.85:T; Gab Message From CTMon 14:09:30

The first 2 digits are the station number that the message came from (11)

11:Stn11:172.25.66.85:T; Gab Message From CTMon 14:09:30

The next field is the Station Alias for that station number as found in the file MULTI.CFG

11:Stn11:172.25.66.85:T; Gab Message From CTMon 14:09:30

The next field is the either the IP address of the station that sent the message or the word 'Serial' if the message came from the serial port.

11:Stn11:172.25.66.85:T; Gab Message From CTMon 14:09:30

The rest of the line is the CT message as received from the port, minus the checksum and ending line feed. The first two bytes of the message are the message type and the station number.

11:Stn11:172.25.66.85:M; 14172500 [CRCCalc:BC CRCRcvd:BC Len:13]

If Show Debug Info is enabled in the setup the message will be followed by 3 fields that are the checksum that was calculated from the received message, the checksum that was in the message and the length of the message, including the checksum and terminating linefeed. Note that even if Show Debug Info is off, these fields will be show for messages that have checksum errors in them.

On the Bottom Portion the transmitted message are displayed.

LOC>UDP---B; 7125.8 XL6Q 24-Mar-1999 1418Z

The first field is a designator showing the route of the message. The following 4 types are generated

LOC>UDPMessage Originated in the local machine and was sent to the Ethernet (UDP protocol)

LOC>SERMessage Originated in the local machine and was sent to the serial port

SER>UDPMessage came in the serial port and was sent out the Ethernet port.

UDP>SERMessage came in the Ethernet and was sent out the serial port.

LOC>UDP---B; 7125.8 XL6Q 24-Mar-1999 1418Z

The rest of the message is displayed as it was sent out to the port. Again the first two bytes of the message are the message type and the station number. The message Checksum and trailing newline character are not displayed.

Loged messages are kept in a file that is based on the date. The format of the file name is 'yymmdd.txt' so a file that was created on Feburary 23, 1999 would have the file name 99Feb23.txt
