Module: CNT242-MIB
OID (symbolic): CNT242-MIB::cnt2esconFreeGlobalMem
OID (numeric): 1.3.6.1.4.1.333.2.4.2.1.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The total amount of global memory available represented in bytes. Global memory is used for buffers.
What is cnt2esconFreeGlobalMem?
This INTEGER reports the amount of global, buffer, memory currently free on this ESCON adapter, in bytes. An administrator watches for this value approaching zero as a precursor to buffer-starvation-related I/O errors on that adapter. For example, cnt2esconFreeGlobalMem nearing zero during a period of heavy channel activity warns the admin that buffer exhaustion could soon disrupt ESCON transfers on that card.
