Memory Utilization

The Memory Utilization Monitor displays overall memory usage over time, providing information about peak memory usage. This indicates whether there is sufficient memory to handle the size of the visibility fabric managed by GigaVUE‑FM. For example, memory usage above a high-utilization mark over a period for more than 30 minutes could indicate that the amount of memory supplied to GigaVUE‑FM is insufficient.

The Memory Utilization Monitor displays utilization as dough nut and time charts. The dough nut chart shows the percentage of utilized and available memory. The time chart shows utilization as specific intervals. By clicking on a point in the time chart, you can see the utilization at a specific point in time. In the following figure, the memory utilization at 11:48:49 AM is 17 percent.

Memory Utilization Monitor

Note:  When GigaVUE-FM starts up, the Memory Utilization Monitor displays around 60-65%. The utilization slowly increases up to 85% with the back end operations running and the memory gets stabilized at this point. A spike in memory is also observed when syslogs are more than usual.
