Server Statistics Meaning

These values are from the Server Statistics dumps that happen at specified intervals on the server. All of these stats are reset to zero after they are dumped. The values represent totals since the last stats dump.

PSNT – UDP packets sent from server to client

PRCV – UDP packets received at server from client

KBSNT – Kilobytes of data sent from server to client

KBRCV – Kilobytes of data received at server from client

OOS – Packets received from the client that are out of sequence

RTX – Packets sent to client that had to be retransmitted

DUP – Packets received from client that are duplicates of those already received

SOK – SYNC OK events. These are triggered when the client is idle for two-plus seconds where the client sends a SYNC to the server and the server reports that the client and server are synchronized (OK).

AGD – Aged SYNC packets. This number refers to consecutive SYNC packets that have been read from the IP stack. This number should be close to ZERO under normal circumstances. If we see a lot of these, it could point to a lack of processor, memory or thread resources for the Stay-Linked Server process on the server machine.

TXF – Transmit Buffer Full. This number represents a count of packets that we tried to send to the device, but there was no room in the server's transmit buffer. If the server is receiving keys or scans from the device and sending screen updates to the device, but the device has not acknowledged receipt of those screen update packets, then the 32-packet transmit buffer on the server could overflow. High numbers here could point to problems delivering packets outbound to the devices.

RCO – Reconnects. This number represents the number of times the client reconnected to an existing session. In these cases, the user will be placed back on their original telnet screen with their original cursor location. Typically this happens if the user has been trained to reboot the device for any reason.

KEY – Number of keypresses processed.

SCN – Number of barcode scans processed.
