AlphaCom system log

The AlphaCom system log provides technical events for monitoring the health of the AlphaCom system. The system log includes the following type of events:

AlphaPro log configuration

• Station Line error
• Board down
• Device/card cage error
• AGA line error
• Software error
• Remote input on/off
• Customized event logging

In AlphaPro (Exchange & System > System > Logs and Errors) it is possible to configure what events to include in the system log. By default all events are included.

It is also possible to configure customized events in the system log. This is done in the Event Handler by using the LOG command.

Log events

Station line error

Traditional (analog) stations

Line Down: The line monitoring feature of the AlphaCom will detect when there is a station line error. Stations are reported down only (not UP). Here line error is reported on station 102. The line board is located in positon 1, port 2:

Oct 11 14:06:21 src@Johnson AlphaLog: N001.D065:.Exch:@D65.B01-2 Line Down: CD Open St 2 "102 -"

IP Stations

The IP substation is supervised in two different ways.

1. Each IP-sub-stations have its own unique TCP socket for data communication. This socket send TCP-alive frames every 5 second, thus a broken socket is discovered within 10 seconds and reported as line error from AlphaCom.
2. From the Application layer AlphaCom is sending a "PING" approximately every 90 second. The stations reply with a "PONG". If one PONG is missing the station is reported as line fault.

IP station down

IP station down is reported on the log port in the two following ways (Data communication is lost, no PING reply or socket closed):

930: Feb 13 16:17:58 src@Node1 AlphaLog: N001.D065:.Exch:@D65.B25-1  Line Down: IP ST Data Com St 20  "1001 -"

IP station down is also reported to the event handler "faulty station line" ON/OFF.

No license

If a new license key is entered with no IP station licenses or not enough licenses, then some stations will be out of business:

933: Feb 13 16:21:34 src@Node1 AlphaLog: N001.D065:.Exch:@D65.B25-1  Line Down: IP ST License St 20  "1001 -"

The system station will report like ordinary line faults with reference to master board and first port (B25-1) since the IP station is not related to any physical AMC board position.

Board error

Board Down is reported when the AMC-board fail to communicate with a board inside the module. Board error is reported down only (not up). Here the board in position 9 is reported down:

Device error

Device Error is reported if the communication between the AlphaCom and the device fails. A "device" is normally a RIO unit). Here there is an error communicating with device #1:

Oct 10 17:51:36 src@Johnson AlphaLog: N001.D065:.Exch:@D01        Device Error

Device OK is reported when the communication becomes OK, and also after restart of the AlphaCom exchange:

Oct 10 17:51:37 src@Johnson AlphaLog: N001.D065:.Exch:@D01        Device OK

Device Missing is reported if the device is not responding after AlphaCom startup:

Oct 11 16:16:54 src@Johnson AlphaLog: N001.D065:.Exch:@D02        Device Missing

Card Cage

Reported OK when all boards in the module are up and running (the module is operational)

Oct 10 12:54:45 src@Johnson AlphaLog: N001.D065:.Exch:@D65        Card Cage OK

AGA error

AlphaNet Line Down is reported if the AGA or AE1 audio link between two nodes in AlphaNet becomes faulty. Here the first line on board position 23 (B23-1) is reported faulty. The audio links are supervised by a test tone issued at regular intervals. Signal Level (SL) is the level measured when there is supposed to be a tone, Noise Level (NL) is the measured level when there is no tone (silence). Signal level is normally in the range 80 - 90. If the signal level is below 40, the AGA error is reported.

Oct 13 14:23:28 src@AlphaComE AlphaLog: N001.D065:.Exch:@D65.B23-1  AlphaNet Line Down:SL=  8 NL=  8

AlphaNet Line Up is reported when the audio link becomes OK. Signal level is 86 in this example:

Oct 13 14:23:59 src@AlphaComE AlphaLog: N001.D065:.Exch:@D65.B23-1  AlphaNet Line Up:SL=86 NL=  8

Remote Control Input RCI

ALARM xx ON: RCI's are reported ON and OFF. The number indicate the logical RCI number.

Oct 13 14:22:41 src@Johnson AlphaLog: N001.D065:.Exch:ALARM 1 ON.
Oct 13 14:22:39 src@Johnson AlphaLog: N001.D065:.Exch:ALARM 1 OFF.

System reports

AlphaPro log-in

AlphaPro is using port 60001. The system log will show the IP address of the PC that has logged on the the AlphaCom:

Oct 10 12:46:20 src@Johnson AlphaLog: N001.D065:.Exch:DP 33 CONN TCP-IP Server Port: 60001 IP:10.5.101.111

TCP-IP connections

TCP-IP connections are logged. MultiModule over IP is using TCP port 50010 and shows connection between master and slave module. Here a device with IP address 10.5.101.42 has connected (and disconnected) to port 4001.

Serial port initialization

When serial ports are configured in AlphaPro, log events are reported when serial port 0 and 1 is initialized by the AlphaCom:
