12 Monitoring System Configuration and Hardware
This chapter provides information on monitoring your system.You can use Network Voyager to monitor many aspects of your IP security platform in order to better maintain performance and security. You can, for example, monitor state information for each interface, view the contents of IP routing tables, and generate reports on events such as throughput, bandwidth utilization, and link states over specific periods of time.
Viewing System Utilization Statistics
Use the system utilization statistics to monitor and tune the allocation of system resources. For example, if the percentage shown under file system capacity becomes a high percentage, you should take action, such as deleting old IPSO images and packages or move your log files to a remote system.

CPU-Memory Live Utilization
The
The CPU Utilization summarizes the load averages, which are the number of processes in the system run queue averaged over the last 1, 5, and 15 minutes, respectively. Load averages that are high, such as over 2 in all three fields, indicate that the system is under continuous heavy load.
The memory utilization summarizes memory usage in KBs. Free memory (memory that is available to the operating system) is defined as free pages + cache pages. The remainder is active memory (memory the operating system is currently using). The free memory might differ (will mostly be lower) as compared to output of a vmstat command.
