          The sysstat utilities are a collection of performance

          monitoring tools for Linux. These include sar, sadf, mpstat,

          iostat, pidstat and sa tools.

​

          Some Features :

​

           * Input / Output and transfer rate statistics (global, per

             device, per partition, per network filesystem and per

             Linux task / PID)

           * CPU statistics (global, per CPU and per Linux task /

             PID), including support for virtualization architectures

           * Memory and swap space utilization statistics

           * Virtual memory, paging and fault statistics

           * Per-task (per-PID) memory and page fault statistics

           * Global CPU and page fault statistics for tasks and all

             their children

           * Process creation activity

           * Interrupt statistics (global, per CPU and per interrupt,

             including potential APIC interrupt sources)

           * Extensive network statistics: network interface activity

             (number of packets and kB received and transmitted per

             second, etc.) including failures from network devices;

             network traffic statistics for IP, TCP, ICMP and UDP

             protocols based on SNMPv2 standards; support for

             IPv6-related protocols.

           * NFS server and client activity

           * Socket statistics

           * Run queue and system load statistics

           * Kernel internal tables utilization statistics

           * System and per Linux task switching activity

           * Swapping statistics

           * TTY device activity

           * Power management statistics
