Yes, write an external program. Call it "find_result.pl" or some
such...
#!/usr/bin/perl -w
use lib qw(/usr/local/mrtg-2/lib/mrtg2/);
use SNMP_util;
my ($first, $second, $third) = snmpget($ARGV[0],
'1.3.6.1.4..', #replace this with the first OID
'1.3.6.1.4..', #and the second oid, etc...
'1.3.6.1.4..');
my $result = 100 * ($first+$second) / $third;
print "$result\n0\n0\n0\n";
then call the program with:
Target[somename]: `find_result.pl [EMAIL PROTECTED]
maxbytes[somename]: 100
options[somename]: gauge
