Linux Vmstat action record saved as file

Encountered a problem. The operation of the machine at night needs to be monitored. Use Vmsata to save the log as a file. Look the next day.

Method Vmstat >a.log

Disadvantage: Unable to display the specific time of each record.

Workaround. Write another script to write time to the A.log file

The script is as follows a.sh

While:
Todo
echo ' Date ' >>a.log
Sleep 600
Done

The final method. 1. First start timed write time script nohup sh a.sh &

2. Start Vmstat:nohup Vmstat >a.log (mainly here is a > number)

Add if only monitor load average can use the following script, also use Nohup to start

While:
Todo
echo ' Date ' >>e.txt
echo ' Uptime ' >>e.txt
Sleep 60
Done
