4.3 Monitoring Errors and Lost Messages

Note: The following information applies only to Intel Dialogic Springware boards.

Errors and lost messages are important indicators of a telephony application's stability. Errors are generated by the Intel Dialogic host drivers or board firmware when a request is made for a function that they cannot perform. Lost messages indicate malfunctioning of the driver or firmware. The presence of errors and lost messages indicates a potential problem that should be addressed.

You can monitor errors and lost messages with the OIDs specified in Table 1. All of the OIDs listed in Table 1 are contained in the Springware Performance MIB (dlgsrprf.mib). They are refreshed periodically for an interval that can be specified with the dlgPsPollingInterval OID in the dlgsrprf.mib.

Table 1. OIDs for Critical Errors 

OID	Description
dlgPsCurrentLostMsgToFW	Number of messages sent from the driver to the firmware that were lost.
dlgPsCurrentLostMsgFromFW	Number of messages sent from the firmware to the driver that were lost.
dlgPsCurrentFWErrorMsgs	Number of error messages generated by the firmware.
dlgPsCurrentDrvErrorMsgs	Number of error messages generated by the driver.

If errors or lost messages occur, resetting the system may clear the problem; for instructions, see Section 2.3, "Stopping and Starting the System". If you continue to encounter errors or lost messages, take note of the frequency and types of errors in a given interval and report the problem to your telephony application developer.
