If everybody who has done similar hacks can send me their magic, then maybe we can fold it into the code, and create a more universal script. We will just have to get past the ksh/bash difference of opinion. :-)

Hi,
Jason and I have hacked at the iostat and got something that seems to work on Linux. We have not cleaned it up near enough or fixed all that we need. Along with changing the script, the graph definitions need to also be changed. Here is the what we have done with iostat so far:
#!/bin/bash OS=$(uname -o) PID=$$
if [[ ${OS} == "solaris" ]] then IOSTAT='/usr/bin/iostat -xrn' else IOSTAT='/usr/bin/iostat -x' fi
TEMPFILE=${BBTMP}/diskstat.tmp.${PID} SHOW_NFS=no # Set this to yes on server side clientlocal.cfg to change it # DISKSTAT:SHOW_NFS=yes DURATION=270 # The duration of the iostat sample # This can be updated in the same way as above
Now we redefine some variables, if they are set in clientlocal
LOGFETCH=${BBTMP}/logfetch.$(uname -n).cfg if [ -f ${LOGFETCH} ] then grep "^DISKSTAT:" ${LOGFETCH} | cut -d":" -f2
| while read NEW_DEF do ${NEW_DEF} done fi${TEMPFILE} # Make sure it's empty
TEMPFILERAW="${TEMPFILE}.raw" ${IOSTAT} $DURATION 2 > ${TEMPFILERAW} # And collect some data to work with.
We have to collect 2 sets, because the first set is the average since
boot.
Define where the second set of data starts
LINE=$(cat ${TEMPFILERAW} | grep -n "^Device:" | tail -1 | cut -d":" -f1)
take the second set, and massage it into usable data
TEMPFILEDATA="${TEMPFILE}.data" if [[ ${OS} == "solaris" ]] then cat ${TEMPFILERAW} | awk "NR>${LINE}"
| sed "s/,/ /g"
| awk '{ print $NF" "$0 }'
| awk '{ $NF="";print }' > ${TEMPFILEDATA} else cat ${TEMPFILERAW} | awk "NR>${LINE}"
| awk '{ print $0" "$1 }'
| awk '{ $NF="";print }' > ${TEMPFILEDATA} fi rm ${TEMPFILERAW}Now we format the data and send it off to the server
if [[ ${OS} == "solaris" ]] then COLUMNS="reads writes kreads kwrites wait actv svct pw pb" else COLUMNS="rrqm wrqm r w rsec wsec avgrq-sz avgqu-sz await svctm util" fi count=1 for subtest in ${COLUMNS} do ((count=count+1)) echo "" >> ${TEMPFILE} cat ${TEMPFILEDATA} | cut -d" " -f1,${count}
| while read DEVICE VAL do echo "${DEVICE}" | grep ":/" > /dev/null if [ $? -eq 0 -a "${SHOW_NFS}" = "no" ] then break else DEVICE=$(echo ${DEVICE} | tr : - ) fi echo "${DEVICE}:${VAL}" >> ${TEMPFILE} done echo "" >> ${TEMPFILE} ${BB} ${BBDISP} "data ${MACHINE}.diskstat-${subtest} $(echo; cat ${TEMPFILE} ;echo "" ;echo "ignore this" )" # Without the last echo "ignore this", it seems to not graph the last entry. # Odd really, but that seems to fix it. rm ${TEMPFILE} done rm ${TEMPFILEDATA}-- Isaac Traxler AIX,Linux Admin Louisiana State University traxler at lsu.edu High Performance Computing 225-578-1923 LONI AIX Clusters AIX, Linux Support

Sorry I can't reply to the thread for some reason i quit receiving the emails, I checked the archive and noticed the replies to my former thread. ( thanks ! )
Vernon, since I don't run solaris here, only linux and some tru64, the -r ( csv output ) and -n ( friendly names ) options makes it hard to use your shell script since they either don't exists or don't work the same. Can you perhaps provide a same output of "iostat -xrn" and along with formated text you pass to hobbit in your check.
I can then provide a snippet of code for linux, which would provide the equivalent output. So you could just add a case in the shell script.

unamein Linux) /usr/bin/iostat -x $DURATION 2 | wonderful stuff > $TEMPFILE.raw ;; SunOS) /usr/bin/iostat -xrn $DURATION 2 > $TEMPFILE.raw ;; esac-- Dan
