DESCRIPTION
"New MIB module for monitoring the memory pools
of all physical entities on a managed system."
REVISION "200812050000Z"
DESCRIPTION
"Added the following High Capacity and Overflow objects
in cempMemPoolTable.
cempMemPoolUsedOvrflw, cempMemPoolHCUsed,
cempMemPoolFreeOvrflw, cempMemPoolHCFree,
cempMemPoolLargestFreeOvrflw, cempMemPoolHCLargestFree,
cempMemPoolLowestFreeOvrflw, cempMemPoolHCLowestFree,
cempMemPoolUsedLowWaterMarkOvrflw,
cempMemPoolHCUsedLowWaterMark,
cempMemPoolSharedOvrflw, cempMemPoolHCShared.
Added couple of new groups cempMemPoolHCGroup and
cempMemPoolOvrflwGroup.
Added a new compliance cempMIBComplianceRev3 which deprecates
cempMIBComplianceRev2."
REVISION "200805070000Z"
DESCRIPTION
"Added a new object cempMemPoolShared in cempMemPoolTable.
Deprecated cempMemPoolGroup OBJECT-GROUP.
Added cempMemPoolGroupRev1 OBJECT-GROUP.
Deprecated cempMIBComplianceRev1 MODULE-COMPLIANCE.
Added cempMIBComplianceRev2 MODULE-COMPLIANCE."
REVISION "200302240000Z"
DESCRIPTION
"Revised version of this MIB,added Objects
to the existing cempMemPoolTable, added buffer pools.
Different types of memory buffer pools
may be present in a managed device. For example:
1. Public buffers, these are standard pools of packets
of different sizes (eg: 104B, 600B, 1536B, 4520B,
5024B, 18024B ...).
2. Private [Interface] buffers (eg. ipc, channel ...).
3. Header pool.
Pool of dynamic packet headers. Header buffers
have no associated data blocks or particles.
(Particles are a mechanism for representing a
data packet as a collection of discontigious
buffers.).
The new objects added are
cempMemPoolUsedLowWaterMark, cempMemPoolAllocHit,
cempMemPoolAllocMiss, cempMemPoolFreeHit,
cempMemPoolFreeMiss, cempMemBufferPoolTable
& cempMemBufferCachePoolTable."

DESCRIPTION
"A unique value, greater than zero, for each memory
pool in a particular physical entity. It is recommended
that values are assigned contiguously starting from 1
such that the index will be unique within a particular
physical entity."
SYNTAX Integer32 (1..2147483647)
CempMemPoolIndexOrNone ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"This textual convention is an extension of the
CempMemPoolIndex. The latter defines a value greater
than zero to identify a memory pool in a particular
physical entity. This extension permits the additional
value of zero. The value zero is object-specific and
must therefore be defined as part of the description
of any object which uses this syntax. Examples of the
usage of zero might include situations where memory
pool was unknown, or when none or all memory pools
need to be referenced."
SYNTAX Integer32 (0..2147483647)
CempMemPoolTypes ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Represents the different types of memory pools that
may be present in a managed device.
Note that only the processor pool is required to be
supported by all devices. Support for other pool types
is dependent on the device being managed.
processorMemory -
processor associated heap memory.
ioMemory -
shared memory for buffer data and
controller descriptor blocks.
pciMemory -
Peripheral Component Interconnect bus
memory which is visible to all devices on
the PCI buses in a platform.
fastMemory -
memory defined by the particular platform
for speed critical applications.
multibusMemory -
memory present on some platforms that
is used as a fallback pool.
interruptStackMemory -
memory for allocating interrupt stacks.
It is usually allocated from heap.
processStackMemory -
memory for allocating process stacks.
It is usually allocated from heap.
localExceptionMemory -
memory reserved for processing
a system core dump.
virtualMemory -
memory used to increase available RAM.
reservedMemory -
memory used for packet headers,
particle headers and particles.
imageMemory -
memory which corresponds to the image
file system.
asicMemory -
Application Specific Integrated Circuit
memory.
posixMemory -
Heap memory associated with posix style
processes in ion."

cempMemBufferPoolTable OBJECT-TYPE
SYNTAX SEQUENCE OF CempMemBufferPoolEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"Entries in this table define entities (buffer pools
in this case) which are contained in an entity
(memory pool) defined by an entry from
cempMemPoolTable.
-- Basic Pool Architecture --
1)Pools are classified as being either Static or
Dynamic. Static pools make no attempt to increase
the number of buffers contained within them if the
number of free buffers (cempMemBufferFree) are less
than the number of minimum buffers (cempMemBufferMin).
With Dynamic pools, the pool attempts to meet the
demands of its users.
2)Buffers in a pool are classified as being either
Permanent or Temporary. Permanent buffers, as their
name suggests, are always in the pool and are never
destroyed unless the number of permanent buffers
(cempMemBufferPermanent) is changed. Temporary
buffers are transient buffers that are created in
dynamic pools whenever the free count
(cempMemBufferFree) of buffers in the pool drops
below the minimum (cempMemBufferMin).
3)Buffers pools are classified as either Public or
Private. Public pools are available for all users
to allocate buffers from. Private pools are
primarily used by interface drivers."

DESCRIPTION
"A table that lists the cache buffer pools
configured on a managed system.
1)To provide a noticeable performance boost,
Cache Pool can be used. A Cache Pool is effectively
a lookaside list of free buffers that can be
accessed quickly. Cache Pool is tied to Buffer Pool.
2)Cache pools can optionally have a threshold value
on the number of cache buffers used in a pool. This
can provide flow control management by having a
implementation specific approach such as invoking a
vector when pool cache rises above the optional
threshold set for it on creation."

DESCRIPTION
"Each entry represents one of the cache buffer pools
available in the system and it contains the
parameters configured for it.
Note : cempMemBufferCachePoolTable has a sparse
dependency with cempMemBufferPoolTable (i.e all the
entires in cempMemBufferPoolTable need not have an
entry in cempMemBufferCachePoolTable."
