krNumOfFileTblOvrFlow
Module: KERNEL-READER-SUNMANAGEMENTCENTER-MIB
OID (symbolic): KERNEL-READER-SUNMANAGEMENTCENTER-MIB::krNumOfFileTblOvrFlow
OID (numeric): 1.3.6.1.4.1.42.2.12.2.2.12.5.5.1.1.16
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The rate of number of file table overflows. Number of file table overflows is calculated at different times which is either when refresh interval reaches or when the mannual refresh is issued. If at time T1 the value is X and at time T2 the value is Y then krNumOfFileTblOvrFlow = (Y - X)/(T2 - T1).
What is krNumOfFileTblOvrFlow?
Rate of file table overflow events on this CPU; a nonzero rate signals the kernel's open-file table limit is being hit, which can cause 'too many open files'-style failures under load.
