[hobbit] temperature script compatible with Hobbit

Thu Aug 2 00:59:01 CEST 2007

 Ralph Mitchell,
At client side I installed hobbit side, At servers side already so many client are connected, when I am trying to such for this client at hobbit server web page , host not found, could u please tell me am I need to update any file about new Linux client.

Thanks

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

	Found this in old email (Dec 06): 
	Jerry Yu <jjj863 at gmail.com> <mailto:jjj863 at gmail.com>      
	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.
