Diagnostic Counters

Server Time

This time stamp shows the time reported by the AVL Service. This is a reliable way to confirm that the information on this page is updating every second.

Unit Count

The number of units listed in the system. Not all are necessarily reporting at this time.

GPS Reports Recvd

The number of recognized GPS reports directly received by this AVL service on either the UDP or COM port since the AVL Service was last restarted. This also includes reports from the CES interface. This does not include GPS updates relayed from other AVL Servers or from any custom interface programs.

UDP Interface

Stats about the UDP listener thread (incoming GPS)

•Status: "running" indicates that the thread is operating normally. "stopped" indicates that the thread has exited possibly due to an error. "stopping" indicates that the thread has been told to stop but has not stopped yet.

•Bytes Received: The number of bytes received on the UDP port since the service was last restarted. This consists primarily of GPS reports but other incoming UDP traffic could be older Think GIS clients, or other supplemental WTH software.

•Bytes Sent: The total number of bytes sent out on the UDP port since the service was last restarted. This number may be zero and would consist only of communication to older Think GIS or other older supplemental WTH software.

•Errors: Number of exceptions that have occurred in the UDP listener thread. Errors are logged to the AVLServer log files

•TAIP: number of TAIP format GPS reports received

•RAP: number of RAP format GPS reports received

•LTI: number of LTI format GPS reports received

•BioKey: number of Bio Key format GPS reports received

•Other: number of other misc known UDP packets received

•Unknown: number of packets received of an unknown format. Possibly garbled transmissions.

COM Interface

Stats about the RS232 listener thread (incoming GPS)

•Status: "running" indicates that the thread is operating normally. "stopped" indicates that the thread has exited possibly due to an error. "stopping" indicates that the thread has been told to stop but has not stopped yet.

•Bytes Received: number of bytes received on the COM port since the service restarted.

•Errors: Number of exceptions that have occurred in the COM listener thread since it restarted. Errors are logged to the AVLServer log files.

•LTI: Number of LTI format GPS reports received

•Unknown: Number of packets received of an unknown format.

TCP Interface

Stats about the TCP listener (client connections)

•Status: This is the status of the thread that is listening for new client connections

•Connections: The number of TCP clients connected to the AVL Server. Includes Think GIS's, AVL Administrator's, and even other AVL Servers. See Client Connections.

•Bytes Received: The total number of bytes received from all client connections

•Bytes Sent: The total number of bytes sent to all clients

•Pac Received: The total number of packets received from all clients

•Errors: The total number of exceptions that have occurred in all client threads

TCP GPS Interface

The TCP Interface is only for client connections received on the specified TcpPort. The TCP GPS Interface is for packets received on the specified TcpGpsPort, including but not limited to Taip packets, NMEA packets, and Traccar packets.

•Bytes Recvd: total bytes received on TcpGpsPort

•Traccar: number of traccar packets received

•Archive: number of traccar packets where the timestamp is older than 1 minute

Server Input Interface

Stats about the Server Input listener thread. (Connections to other AVL Servers)

•Status: State of thread that is responsible for requesting GPS input from other AVL Servers

•Connections N/M: M=total number of other AVL Servers that this server is trying to communicate with. N=number of servers that this AVL Server has successfully connected to. See AVLServer log for error messages.

•Bytes Received: Total number of bytes received in responses from other AVL Servers

•Pac Received: Total number of packets received from other servers

•Errors: Total number of exceptions that have occurred in Server Input Listener thread. See AVLServer log files.

CES Interface

Stats about the CES listener thread. (GPS Input)

•Status: Status of the thread that listens for GPS reports from CES Wireless software.

•Bytes Received: Number of bytes received from CES

•Pac Recvd: Number of packets received from CES

•Errors: Number of Exceptions that have occurred in CES listener thread. See AVLServer log files.

Misc

Other parameters

•Admin Timer Errors: Admin timer does periodic checks of the system

•Udp Viewers Connected: This is the number of Think GIS clients using the older UDP communication method. These clients are listed with a type of 'U' in the Client Connections List. Tod disallow these older connections see Output tab.

•Shift Changes: The number of times the old shift change program has been executed. This is an older program now obsoleted by AVL Administrator.

•Admin Timer Ticks: A constantly incrementing number here confirms that the admin timer is running.
