sTrapLostCount
Module: COMTEK-VMS-NM-SYSMGR-MIB
OID (symbolic): COMTEK-VMS-NM-SYSMGR-MIB::sTrapLostCount
OID (numeric): 1.3.6.1.4.1.597.4.3.3.5
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This variable indicates the number of traps that have been lost. A trap is considered to be lost if it is overwritten in the internal trap table before it is sent to the NMS. This may occur if the trap table is not large enough (see sCfgTrapTblSize) to hold all of unsent traps. How quickly traps are sent to the NMS is governed by the sCfgMaxTrapSec variable. To prevent trap loss, set these two variables so that the trap backlog does not overflow the trap table and so that traps do not flood the network.
What is sTrapLostCount?
This is a count of traps that were overwritten in the internal trap table before they could be sent to the network management station, meaning they are permanently lost. An administrator monitors this counter to detect when the trap table (sCfgTrapTblSize) is too small or the send rate (sCfgMaxTrapSec) is too low for the volume of events being generated. For example, a rising sTrapLostCount during a period of many hardware errors would prompt the administrator to increase the trap table size to avoid losing future alerts.
