Hot! Hot! Hot! (a slight variation on "Watching mail queues")

Our Computers Room is too hot today...

Similar problem as before, but with an important variation: I had to match just a small range of lines in the output of a command. This one-liner now runs on a Sun Ultra-Enterprise host running Solaris 8, and a monitoring software reads and reports the temperatures of the system boards.

/usr/platform/sun4u/sbin/prtdiag -v | perl -ne 'BEGIN { print "TABLE temperature\nSTART_SAMPLE_PERIOD\n" } ; END { print join ("NEXT_SAMPLE\n",@samples),"END_SAMPLE_PERIOD\nEND_TABLE\nSLEEP\n" } ; if (/^System Temperatures/../^$/) { next unless /^(CLK|\s*\d+)/ ; ($b,$t) = (split)[0,2] ; push @samples,"board=$b\ntemp=$t\n" }'

Have fun


In theory, there is no difference between theory and practice. In practice, there is.

    Wow bronto! These little utilities you write are so tight, you could print them on a label and attach them to the monitor in the server room. Then we'd never have an excuse for not checking up on the temp or the mail queues :-)
