customizing output of iotop

rajaniyer123 · 01-05-2013, 09:53 AM

Hi,

I would like to set up the cron in which it should capture the top 3 process IDs which will causes the high %IO and Total Disk Read & Write details of iotop command.

So that like sar o/p in future I can check the process ID which causes the high I/O

I know how to set up the cron but unable to find out the way to capture top 3 process IDs which will causes the high %IO and Total Disk Read & Write details of iotop command.

Please suggest.

Thanks
Rajan

Like top, iotop has a batch mode - should be what you're looking for. "iotop -b -n 1 > iotop.out.$(date +%F_%T)" for example.

Something like collectl might (would) be a better option.

Hi,

Thanks for your update, but I am looking for to identify the top 5 process which causes high DISK READ & DISK WRITE and capture only those process into log file.

Thanks
