Not at all. I'm sure other folks with linux servers could find it
handy. I'm even using it to trend the temperature in my home office :)<br>

Subject: Re: [hobbit] temperature script compatible with Hobbit
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).
Here is the script itself:
#!/bin/sh
# THRESHOLD VALUES FOR TEMPERATURE
YTMP=72
RTMP=80
#
SENSORS="/usr/bin/sensors -f"
STMP=${BBTMP}/SENSE.$$
COLOR=green
MSG=default
#
${SENSORS} > ${STMP}
# PARSE TEMPERATURE INFORMATION.
TMP=`${GREP} -i temp ${STMP}|cut -d"(" -f1|cut -d"?" -f1|cut -d"+"
-f2|cut -d"." -f1`
if [ ${TMP} -lt ${YTMP} ];
then
COLOR=green
MSG="The Temperature is currently ${TMP}F, which does not exceed
the Warning level (${YTMP}F)"
fi
if [ ${TMP} -gt ${YTMP} ] && [ ${TMP} -lt ${RTMP} ];
then
COLOR=yellow
MSG="The Temperature is currently ${TMP}F, which is exceeds the
Warning level (${YTMP}F)"
fi
if [ ${TMP} -gt ${RTMP} ];
then
COLOR=red
MSG="The Temperature is currently ${TMP}F, which exceeds the
Panic level (${RTMP}F!)"
fi
rm ${STMP}
$BB $BBDISP "status $MACHINE.temp $COLOR `date`
$MSG
temp : $TMP
"
The script is launched via this addition to clientlaunch.cfg on the
remote machine:
[temp]
ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg
CMD $HOBBITCLIENTHOME/ext/temp.sh
INTERVAL 5m
On the server, here is the addition to hobbitgraph.cfg:
[temp]
TITLE Temperature
YAXIS Degrees Farenheit
DEF:t=temp.rrd:temp:AVERAGE
LINE2:t#@COLOR@:Ambient Temp
GPRINT:t:LAST: \: %5.1lf (cur)
GPRINT:t:MAX: \: %5.1lf (max)
GPRINT:t:MIN: \: %5.1lf (min)
GPRINT:t:AVERAGE: \: %5.1lf (avg)\n
Let's not forget the additions to hobbitserver.cfg:
TEST2RRD="cpu=la,disk,inode,qtree,memory,$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*,temp=ncv*"
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*,temp*"
*NCV_temp="temp:GAUGE"*
I also put a custom rules in hobbit-alerts.cfg:
# Temp alerts
HOST=myhost.mydomain.com SERVICE=temp
MAIL $SYSADMINS color=yellow REPEAT=60 RECOVERED NOTICE
MAIL $SYSADMINS,$SYSADMINS-PAGERS color=red RECOVERED NOTICE
MAIL $BOSS color=red DURATION>60 RECOVERED format=sms

Does anyone have an lm_sensors script that both alerts on temp

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