Viewing Remote Access Service Status and Statistics
The Display Service Status option enables you view statistics for each of the loaded services. Service statistics can be divided into general and custom statistics.
The Service Statistics window lists the service name, whether it is running, whether statistics are available, and the port number. A description of the service is displayed below the Service Statistics window with an explanation of the service's function.
To view a service's statistics, load NIASCFG and follow this path:
Select View Status for NIAS > Remote Access > Display Service Status
Select the service you want to view and press Enter. The statistics for the selected service are displayed.
Viewing NCS Status
Highlight NCS and press F10 to view more status information about the NetWare Asynchronous Services InterfaceTM (NASITM) Connection Service (NCS), as shown in Figure 16. This window also displays remote control hosts on the LAN waiting for calls (if configured to use the dial-in group). The other services (ARAS and PPPRNS) do not provide any additional status information.

Viewing Service Statistics
You can monitor service statistics to diagnose internal problems with the services. To view the service statistics, select the service you want to view from the those listed and press Enter. To reset the statistics counters to zero, press Delete.
PPPRNS Statistics
Service statistics for PPPRNS can be divided into general and custom statistics. Only the custom statistics are explained in this section. For an explanation of general statistics, refer to information on the MONITOR utility in the NetWare documentation. To view the PPPRNS statistics, load NIASCFG and follow this path:
Select View Status for NIAS > Remote Access > Display Service Status > PPPRNS Statistics
Table 28 defines the PPPRNS custom statistics.
Table 28. PPPRNS Custom Statistics
Number of Connected Ports Monitored |
The number of active sessions that PPPRNS is monitoring. |
Reset Statistics Counter |
The number of times you pressed Delete to reset the counters. |
Total Bytes Transmitted |
The total number of bytes that PPPRNS sent from all ports. |
Data Packets Transmitted |
The number of packets transmitted by PPPRNS. |
Total Bytes Received |
The total number of bytes PPPRNS received from all ports. |
Data Packets Received |
The number of packets PPPRNS received from all ports. |
Receive Framing Errors |
The number of invalid frames that PPPRNS received. |
Receive CRC Errors |
If you have cyclic redundancy check (CRC) errors, then you might have data loss. The data loss could be from hardware overrun or corrupted data. Hardware overruns occur if data is arriving too fast for the server to process and the data is being overwritten. During disturbances in the asynchronous link, the incoming byte might be altered, resulting in corrupted data. |
Received Frames Too Big |
If your receive buffer cannot handle the bigger frames from the client, this counter is incremented. This shows problems with the client negotiation. |
No RCB to receive frame |
The number of times PPPRNS cannot acquire a receive buffer to accept an incoming frame. Incoming frames are discarded. This could happen if resources are running low. |
Number of Transmit Frames Tossed |
The number of transmitted frames that were discarded because PPPRNS was too busy. |
TSM Tx Flow Control Errors |
This counter is incremented if PPPTSM sends information when PPPRNS is busy. The problem could be with the flow control handshake. |
NCS Statistics
To view the NCS statistics, load NIASCFG and follow this path:
Select View Status for NIAS > Remote Access > Display Service Status > NCS Statistics
Table 29 defines the custom statistics for NCS.
Table 29. NCS Custom Statistics
Command Interpreter Users |
The number of NASI applications using NCS that have active Command Interpreters (CIs) |
Query Name Requests |
The number of requests to query a general port name or a specific port name |
Packets Input |
The total number of packets input to NCS by NASI applications |
Packets Output |
The total number of packets output by NCS to NASI applications |
Total Connections |
The total number of connections to the NCS ports |
ARAS Statistics
Service statistics for ARAS can be divided into general and custom statistics. Only the custom statistics are explained in this section. For an explanation of general statistics, refer to information about the MONITOR utility in the NetWare documentation.
To view the ARAS statistics, load NIASCFG and follow this path:
Select View Status for NIAS > Remote Access > Display Service Status > ARAS Statistics
Table 30 explains the custom statistics for ARAS.
Table 30. Custom ARAS Statistics
Number of Ports Monitored |
Number of active ports that ARAS is controlling |
Total Bytes Transmitted |
Total number of bytes that ARAS sent out of the serial ports |
Data Packets Transmitted |
Number of packets transmitted by ARAS |
Data Packet Bytes Transmitted |
Number of bytes in all the packets transmitted so far |
Total Bytes Received |
Total number of bytes ARAS received from the serial ports |
Data Packets Received |
Number of packets ARAS received from the serial ports |
Data Packet Bytes Received |
Number of bytes in all the packets received so far |
Receive Framing Errors |
Number of framing errors that ARAS received |
Receive CRC Errors |
Number of cyclic redundancy check (CRC) errors received by ARAS |
Out-of-Sequence Packets Received |
Number of packets ARAS retransmitted because it did not receive an acknowledgment |
Out-of-Sequence Packet Bytes Received |
Number of bytes ARAS retransmitted because it did not receive an acknowledgment |
Requested Retransmits |
Number of times the remote end requested retransmission because data was lost during transmission |
Timeout Retransmits |
Number of times the remote end timed out and ARAS had to retransmit the data |
