While helping our Admin guy monitor some servers , I noticed that ManageEngine was running a command called
LANG=C iostat -d
Which failed as it wasnt installed as part of a rpm called sysstat. So after yum installing sysstat , I was pleasantly suprised how complicated it actually could get. Very useful. Spent a few hours with the tools available (iostat etc.). Could be useful to others and shame on us for not knowing about it sooner!
