That doesn't look like a Solaris script to me but as far as your coding is concerned, my thoughts are (i) get yourself a book on the k-shell 'cause it's a lot more powerful that the bourne (/bin/sh) shell. (ii) you can say vmstat -dp | awk '/sda/ {print $2}' instead of vmstat -dp | grep sda | awk '{print $2}' (iii) if you were using bash or ksh your could say readdiff=$(( $currreads - $prevreads )) instead of readdiff=$(expr $currreads - $prevreads) (iv) for security you ought to use full paths to all of your binaries: i.e. /usr/bin/echo instead of echo Otherwise I guess it'll work in Nagios (although most Nagios plugins can give warnings or critical alerts by exiting with exit codes 0 for OK, or 1 for WARNING, or 2 for CRITICAL.

I'm still learning shell scripting /nagios / etc so i welcome corrections to my logic, coding, anything! :-) It's not really fancy, just uses vmstat to get disk reads and writes, stores it, then compares that the next time. As i said, it's just for mrtg now so dunno if it will work for nagios, but soon i'll play with it and find out.

What options of iostat are they calling etc?
