Nokia Network Voyager for IPSO 4.0 Reference Guide 47912 Monitoring System Configuration andHardwareThis chapter provides information on monitoring your system.You can use Network Voyager tomonitor many aspects of your IP security platform in order to better maintain performance andsecurity. You can, for example, monitor state information for each interface, view the contents ofIP routing tables, and generate reports on events such as throughput, bandwidth utilization, andlink states over specific periods of time.Viewing System Utilization StatisticsUse the system utilization statistics to monitor and tune the allocation of system resources. Forexample, if the percentage shown under file system capacity becomes a high percentage, youshould take action, such as deleting old IPSO images and packages or move your log files to aremote system.To view statistical information on system utilization, click either CPU-Memory Live Utilization,Disk and Swap Space Utilization, or Process Utilization under Monitor > System Utilization inthe tree view.CPU-Memory Live UtilizationThe CPU-Memory Live Utilization page shows system resources usage, including CPU andmemory usage. This page retrieves the updated CPU and memory usage every 20 seconds.The CPU Utilization summarizes the load averages, which are the number of processes in thesystem run queue averaged over the last 1, 5, and 15 minutes, respectively. Load averages thatare high, such as over 2 in all three fields, indicate that the system is under continuous heavyload.The memory utilization summarizes memory usage in KBs. Free memory (memory that isavailable to the operating system) is defined as free pages + cache pages. The remainder is activememory (memory the operating system is currently using). The free memory might differ (willmostly be lower) as compared to output of a vmstat command.
