There are also negative experiences with the program xagt.exe (FireEye Endpoint Security), which (probably due to missing exceptions) consumed quite a lot of CPU power (4 out of 16 available CPUs) and disabled several real-time communications (IEC 870-5-101 and IEC 870-5-104 protocols).

Useful diagnostic tools

On the Windows platform:

  • Resource monitor (available from Task Manager) - display statistics about CPU, memory consumption, disk operations and network usage

On the Linux platform:

  • the iotop utility is used to display statistics of disk operations
    iotop (interactive display of current values for individual processes)
    iotop -ao (display cumulative I/O statistics of individual processes)

  • ps utility (display information about individual processes)
    ps -eo pcpu,pid,user,args | sort -nk 1 -r | head -20 (display all processes - CPU usage, process PID, username and arguments - and sort by CPU, showing the 20 processes with the highest CPU usage)
