[mrtg] Re: UPS Battery Time Question

[Herold Heiko]

If you are using upsAdvBatteryRunTimeRemaining you probably need to convert
the data with an external command, unless I'm not up to date with current
mrtg.
Personally I invoke a perl script like this (watch the wrap)

Target[apc-symmetra.upsAdvBatteryRunTimeRemaining]:
`/home/mrtg/run/convtimeticks.pl apchostname password -m ~/Mibs/powernet.mib
upsAdvBatteryRunTimeRemaining.0`

which in turn runs a ucd-snmp tool like this

snmpget -Oq -Ot -m ~/Mibs/powernet.mib apchostname password
upsAdvBatteryRunTimeRemaining.0

The key is the -Ot, which means:  "Output timeticks values as raw numbers."
snmpget would print something like
enterprises.apc.products.hardware.ups.upsBattery.upsAdvBattery.upsAdvBattery
RunTimeRemaining.0 84000

while convtimeticks.pl would print the 4-line output mrtg expects:
840
0

apc

The script is like this:

#!/usr/bin/perl 
#invoke like $0 host <snmpcommand-args> community sysUpTime.0
$host = $ARGV[0] || " ";
$command="snmpget -Oq -Ot ".join " ", at ARGV;
$in=`$command`;
$_=((split /\s+/,$in)[1] or 0);
$_ /= 100;
print	int($_),"\n","0\n"," \n","$host\n",;

Bye
Heiko
