vmstat -w 5 - I need a time stamp on the enteries

[Larshg]

Hi

I'm having IO issues on a servere, and I want to monitor this problem over time.

I'm using vmstat -w 5 to monitor the problem - but I would realy like to get a timestamp infront og the lines, so that I have a chance og analysing the system.

Any ideers? - I'm wundering if I should make a script that uses vmstat -w 1 2 and takes the last line. - then putting a time stamp infront of that. - but there must be a better way.

while [ : ]
vmstat -w 1 1
date
sleep 5
done

Or perhaps:

[tt]vmstat -w 5 | while read line ; do echo "$(date): $line" ; done[/tt]
