| − | The '''AlphaCom system log''' provides technical events for monitoring the health of the AlphaCom system. The system log includes the following type of events:
| + | #REDIRECT [[System log]] |
| − | [[Image:AlphaPro System LogsAndErrors.jpg|thumb|right|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.

| |
| − | === 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.
| |
| − | | |
| − | # 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.
| |
| − | # 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):
| |
| − | <pre>
| |
| − | 930: Feb 13 16:17:58 src@Node1 AlphaLog: N001.D065:.Exch:@D65.B25-1 Line Down: IP ST Data Com St 20 "1001 -"
| |
| − | </pre>
| |
| − | IP station down is also reported to the event handler "[[Faulty Station Line (Event Type)|faulty station line]]" ON/OFF.
| |
| − | | |
| − | ===== No license =====
| |
| − | If a new [[Licenses|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:
| |
| − | Oct 11 16:15:15 src@Johnson AlphaLog: N001.D065:.Exch:@D65.B09 Board 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.

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

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