I figured I would share the script and setup that I am now using, Note
that the script is for use with lm_sensors on linux machines, and
tailored for my particular setup (different servers have different
sensors and thus the temperature parsing section may have to be
changed).<br>
<br>
Here is the script itself:<br>
<tt>#!/bin/sh<br>
<br>
# THRESHOLD VALUES FOR TEMPERATURE <br>
YTMP=72<br>
RTMP=80<br>
#<br>
SENSORS="/usr/bin/sensors -f"<br>
STMP=${BBTMP}/SENSE.$$<br>
COLOR=green<br>
MSG=default<br>
#<br>
${SENSORS} > ${STMP}<br>
# PARSE TEMPERATURE INFORMATION.<br>
TMP=`${GREP} -i temp ${STMP}|cut -d"(" -f1|cut -d"�" -f1|cut -d"+"
-f2|cut -d"." -f1`<br>
if [ ${TMP} -lt ${YTMP} ];<br>
then<br>
COLOR=green<br>
MSG="The Temperature is currently ${TMP}F, which does not
exceed the Warning level (${YTMP}F)"<br>
fi<br>
if [ ${TMP} -gt ${YTMP} ] && [ ${TMP} -lt ${RTMP} ];<br>
then<br>
COLOR=yellow<br>
MSG="The Temperature is currently ${TMP}F, which is exceeds
the Warning level (${YTMP}F)"<br>
fi<br>
if [ ${TMP} -gt ${RTMP} ]; <br>
then<br>
COLOR=red<br>
MSG="The Temperature is currently ${TMP}F, which exceeds the
Panic level (${RTMP}F!)"<br>
fi<br>
rm ${STMP}<br>
<br>
$BB $BBDISP "status $MACHINE.temp $COLOR `date` <br>
$MSG<br>
temp : $TMP<br>
"</tt><br>
<br>
The script is launched via this addition to clientlaunch.cfg on the
remote machine:<br>
<tt>[temp]<br>
ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg<br>
CMD $HOBBITCLIENTHOME/ext/temp.sh<br>
INTERVAL 5m</tt><br>
<br>
On the server, here is the addition to hobbitgraph.cfg:<br>
<tt>[temp]<br>
TITLE Temperature<br>
YAXIS Degrees Farenheit<br>
DEF:t=temp.rrd:temp:AVERAGE<br>
LINE2:t#@COLOR@:Ambient Temp<br>
GPRINT:t:LAST: \: %5.1lf (cur)<br>
GPRINT:t:MAX: \: %5.1lf (max)<br>
GPRINT:t:MIN: \: %5.1lf (min)<br>
GPRINT:t:AVERAGE: \: %5.1lf (avg)\n</tt><br>
<br>
Let's not forget the additions to hobbitserver.cfg:<br>
<tt>TEST2RRD="cpu=la,disk,inode,qtree,memory,$PINGCOLUMN=tcp,http=tcp,dns=tcp,dig=tcp,time=ntpstat,vmstat,iostat,netstat,temperature,apache,bind,sendmail,mailq,nmailq=mailq,socks,bea,iishealth,citrix,bbgen,bbtest,bbproxy,hobbit,hobbitd,files,procs=processes,ports,clock,lines<b>,temp=ncv</b>"<br>
GRAPHS="la,disk,inode,qtree,files,processes,memory,users,vmstat,iostat,tcp.http,tcp,ncv,netstat,ifstat,mrtg::1,ports,temperature,ntpstat,apache,bind,sendmail,mailq,socks,bea,iishealth,citrix,bbgen,bbtest,bbproxy,hobbit,hobbitd,clock,lines<b>,temp</b>"<br>
<b>NCV_temp="temp:GAUGE"</b></tt><br>
<br>
I also put a custom rules in hobbit-alerts.cfg:<br>
<tt># Temp alerts<br>
HOST=myhost.mydomain.com SERVICE=temp<br>
MAIL $SYSADMINS color=yellow REPEAT=60 RECOVERED NOTICE<br>
MAIL $SYSADMINS,$SYSADMINS-PAGERS color=red RECOVERED NOTICE<br>
MAIL $BOSS color=red DURATION>60 RECOVERED format=sms<br>
</tt><br>

Found this in old email (Dec 06):
<br>
Jerry Yu <a class="moz-txt-link-rfc2396E" href="mailto:jjj863@gmail.com"><jjj863@gmail.com></a> <br>
never mind, I found the answers in the source code,
<br>
rrd/do_temperature.c. [[ All hail goes to Open Source & Henrik! ]]
<br>
1. a lump-all status command will do. Format of the data portion is
<br>
somewhat restrictive '&green BMCambient 17 62\n&yellow
BMCriserCard 32
<br>
93'. It'd be nice to have such format documented elsewhere other than
<br>
the source code.
<br>
2. if 'temperature' is used as 'test name', nothing needs to be done.
<br>
3. the check can be done locally on the client and the overall $status
<br>
is reported by 'status server1.temperature $status'.
<br>
<br>
So, if the script you hacked up can be persuaded to send a status
<br>
message that looks something like:
<br>
<br>
$BB $BBDISP status "server,domain,com.temperature `date`
<br>
&<color> <variable_name>
<temp_in_celsius> <temp_in_fahrenheit>"
<br>
<br>
you could get graphs. I'm away from my work machines right now, so
<br>
the above may be a little lacking.
<br>
<br>
Alternatively, try the NCV option. Once a status message is set up to
<br>
be pushed through the ncv module, all you need in the status message
<br>
is:
<br>
<br>
<variable name> : <value>
<br>
<br>
Anything on the line before the colon becomes the variable name,
<br>
anything after the colon is the value that gets stored.
