IOS XE committed memory

[paul amaral]

Hi, can someone explain to me what committed memory means in the command below, Is that committed memory being used by the IOS process or committed total by the platform's linux kernel. I researched but could not get a clear answer. 

thanks Paul

#sh platform software status control-processor br
Load Average
Slot Status 1-Min 5-Min 15-Min
1-RP0 Healthy 0.75 0.69 0.68
2-RP0 Healthy 0.15 0.21 0.22

Memory (kB)
Slot Status Total Used (Pct) Free (Pct) Committed (Pct)
1-RP0 Healthy 3976872 2770888 (70%) 1205984 (30%) 2844336 (72%)
2-RP0 Healthy 3976872 1866164 (47%) 2110708 (53%) 2726820 (69%)

Looking at this further it looks like total platform memory committed since the IOS process is only holding 852MB on the same device.

#sh proc memory sorted
Processor Pool Total: 852280752 Used: 348521360 Free: 503759392
lsmpi_io Pool Total: 6295128 Used: 6294296 Free: 832

Committed is the TOTAL amount of memory (Used + Free = Committed).  The total should be 130%.  

For IOX-XE platform, if the Committed is >80% you start to worry.

Leo, thanks. Why 130% does that include virtual memory?

"Reserve" memory.
