Viewing Memory Utilization Levels

Go to Network Analysis > Performance > Performance > Free Memory to view the distribution of free memory on devices in operation over the current reporting period, for all devices on the network or for a chosen device group, for which that data is accessible via SNMP. Each level of memory usage on the X-axis of the chart represents a level of free memory, from the lowest values to the highest values from left to right. All devices falling into specific levels of free memory are grouped into those values on the X-axis.

Devices with low free memory levels can indicate an inefficient or poorly matched configuration such as a router whose routing table or routing information base (RIB) is too large, or possible memory leaks.

Click Graph or Table at the bottom of this page for alternate views of the information. Modify the graph using the Metric, Min, and Max lists in the upper right corner. For example, if Metric is set to Minimum, the distribution shows the lowest free memory value reached for each device during the selected time period.
