Memory Used pointing to which memory ?

Heloo,

NPM 11.5, in the "Average CPU Load & Memory Utilization " view , the Gauge of the "Memory used" , anybody knows this gauge is pointing to which memory type on cisco devices ? There are four main memory areas within a Cisco router : Flash, RAM, ROM, and NVRAM memory so which one is meant by this Gauge ?

I would think ciscoMemoryPoolUsed (1.3.6.1.4.1.9.9.48.1.1.1.5) based on https://support.solarwinds.com/Success_Center/Network_Performance_Monitor_(NPM)/CPU_and_memory_utilization_Object_IDs_(OIDs)_NPM_can_poll

If ASR 9K, this link should help: Monitoring CPU and Memory via SNMP - ASR9K - DocWiki

Which model are you asking about?

@d09h

thx for your reply , however, i was asking about which memory type this gauge is pointing at ? is it pointing to the RAM ?

RAM (DRAM) or system memory (processorRam)

"Indicates the number of bytes from the memory pool that are currently in use by applications on the managed device."

http://www.cisco.com/c/en/us/support/docs/ip/simple-network-management-protocol-snmp/15216-contiguous-memory.html

A—"Total(b)" is the total amount of memory, in bytes, available for the processor after the Cisco IOS software is loaded. If you want to know how much memory the Cisco IOS software takes on the router, subtract the Total bytes shown here from the total amount of dynamic RAM (DRAM) or system memory (processorRam) installed on the router. The total input/output (I/O) memory or Fast memory is based on the physical I/O memory installed on the low-end routers or based on the amount of packet memory allocated on high-end routers from system memory (typically, 2 MB on Route/Switch Processor (RSP) platforms). .1.3.6.1.4.1.9.3.6.6 processorRam OBJECT-TYPE -- FROM OLD-CISCO-CHASSIS-MIB SYNTAX Integer MAX-ACCESS read-only STATUS Deprecated DESCRIPTION "Bytes of RAM available to CPU." ::= { iso(1) org(3) dod(6) internet(1) private(4) enterprises(1) cisco(9) temporary(3) chassis(6) 6 }

B—"Used(b)" is the total amount of memory, in bytes, currently used (ciscoMemoryPoolUsed) by the router. .1.3.6.1.4.1.9.9.48.1.1.1.5 ciscoMemoryPoolUsed OBJECT-TYPE -- FROM CISCO-MEMORY-POOL-MIB SYNTAX Gauge MAX-ACCESS read-only STATUS Current DESCRIPTION "Indicates the number of bytes from the memory pool that are currently in use by applications on the managed device." ::= { iso(1) org(3) dod(6) internet(1) private(4) enterprises(1) cisco(9) ciscoMgmt(9) ciscoMemoryPoolMIB(48) ciscoMemoryPoolObjects(1) ciscoMemoryPoolTable(1) ciscoMemoryPoolEntry(1) 5 }
