Memory Graphs

Memory Usage in %, per Day

Daily Memory Utilization Graph.
This graph depicts both the 'peak' and 'average' memory utilization by day.
The target guideline for scan rate is < 200 per second.
The target Average Scanned / Freed ratio is 5.
If the ratio is > 5 and the scan per second is > 200, then a red flag indicator is shown which
indicates additional memory or system tuning may be needed.
If the ratio is > 5 or the scan per second > 200, then a yellow flag indicator is shown which
suggests tuning may be needed.
If neither of these scenarios exist, then memory is likely not a problem.
The measurement is for the base amount of memory assigned to the partition.
