Subject:	RE: Two or more SNMP templates and custom SNMP port configuration per template on particular device

Here is a sample that i wrote some years back - may help.  I wanted several SNMP values so wrote a script, getPowerValues.sh,  to do the work, taking parameters from the COMMAND performance template (the  ${here/manageIp} ${here/zSnmpCommunity} ${here/zSnmpVer}  - see the comments at the top of the script.

This was part of a ZenPack and you probably dont need to get that complicated so, if you want a script rather than putting everything directly into the COMMAND template, just put the script into $ZENHOME/libexec and use the command name at the start of your COMMAND template rather than my complicated ${here/ZenPackManager/packs/ZenPacks.ZenSystems.olsonPower/path}/lib/getPowerValues.sh.

# Shellscript to use individual snmpget commands to get
# voltage, current, power, energy and temperature from Olson power meters
# Note that all values are delivered as DisplayStrings so an SNMP template
# cannot be used.
# host is first parameter; communty name is second parameter: version is third parameter
#
# Driven by olson_power command performance template
# ${here/ZenPackManager/packs/ZenPacks.ZenSystems.olsonPower/path}/lib/getPowerValues.sh ${here/manageIp} ${here/zSnmpCommunity} ${here/zSnmpVer}

# so convert from string to integer with bc utility

volts=$(/usr/bin/snmpget -$3 -c $2 -O qvU $1 1.3.6.1.4.1.17933.1.1.19 2>/dev/null)

temp=$(/usr/bin/snmpget -$3 -c $2 -O qvU $1 1.3.6.1.4.1.17933.1.1.24 2>/dev/null)
temp=$(echo $temp | bc -l 2>/dev/null)

if [ -n "$volts" ]
then
echo "OK|voltage=$volts current=$amps power=$power energy=$energy temp=$temp"
else echo "Unknown"
fi


Hope that helps,
