a shortcut key to sort by memory footprint. UptimeThe uptime command tells you how long this server has been running since booting up to the present time. It also contains the average load from boot to current server: VmstatYou can use Vmstat to monitor virtual memory, and developers on Linux generally prefer to use virtual memory for optimal storage performance. This command reports statistics about kerne

designed to monitor Ethernet address resolution (changes in Mac and IP addresses) on Linux. He continuously monitors Ethernet activity for a period of time and outputs a log of changes in IP and MAC address pairs. It can also send an email notification to an administrator, alerting you to an increase in address pairing. This is useful for detecting ARP attacks on a network.suricata– Network Security MonitoringSuricata is an open source high-

to monitor as long as you enter a single command. For example, to get statistics on the processor, memory, and disk, just enter C, M, and D separately. You can also use Nmon with the-f flag to save performance statistics to a CSV file for later analysis. As far as day-to-day server monitoring is concerned, I think Nmon is one of the most useful programs in my Linux
