Description (partial)


The <i>MemoryMaxHighUsed</i> value displayed by the 'show statistics virtual-sensor' command output is zero (0) or another incorrect value (possibly a lower value than either/both the <i>MemoryCurrentAllo</i> and/or <i>MemoryCurrentUsed</i> values). Example:

sensor# show statistics virtual-sensor | include Memory
         MemoryAlloPercent = 25
         MemoryUsedPercent = 25
         MemoryMaxCapacity = 2000000
         MemoryMaxHighUsed = 256072  <--INCORRECT VALUE
         MemoryCurrentAllo = 500000
         MemoryCurrentUsed = 498024

This invalidates the use of this value for monitoring/troubleshooting issues related to memory [allocation] on affected sensor devices.
