Issue/Introduction

 
 
 
For some Routers the PM report show an incorrect memory utilization like this:
 
On Spectrum:
 

PM Report by components:

 

Cause

The memory reserved and image are typical of the device operating system very similar to / proc on unix; they will always be 100%.

Environment

PM Release : 3.7

Resolution

DC Debug show:
Item ID=543846, Name=MemoryPool processor 1
Item ID=543847, Name=MemoryPool reserved 6
Item ID=543848, Name=MemoryPool image 7
 
Vertica query:
drdata=> select to_timestamp(tstamp), item_id, im_utilization from dauser.physical_memstats_rate where item_id in (543846,543847,543848) and tstamp >= 1585044000 and tstamp <= 1585044900 order by 1,2;
    to_timestamp     | item_id |  im_utilization

The average from Vertica query is 79% like the CAPC report because the gauges are all Memory components being aggregated together across the entire time range so the report is correct
 
You can create filter like this:

The results are:
