nmon: Save records to file with a total of 240 measurements, by taking 30 seconds between each measurement.
$ nmon -f -s ${30} -c ${240}
try on your machine

This command is using the nmon tool, which is a performance monitoring and diagnostic utility for Linux and AIX systems. It collects system information and presents it in a detailed report.

The specific command you provided, "nmon -f -s ${30} -c ${240}", has the following components:

  • "nmon" is the command to invoke the nmon tool.
  • "-f" specifies that the collected data should be written to a file instead of displaying it on the screen.
  • "-s ${30}" sets the sampling interval to 30 seconds. This means that nmon will collect system information every 30 seconds.
  • "-c ${240}" sets the count or duration to 240. This means that nmon will stop collecting data after 240 iterations (in this case, 30 * 240 = 7200 seconds or 2 hours).

In summary, this command starts the nmon tool and instructs it to collect system information every 30 seconds for a duration of 2 hours, saving the data to a file instead of displaying it on the screen.
